How to choose an exhaust to the kitchen: advice of professionals and useful recommendations. How to choose a kitchen hood - criteria, advice pro and reviews

All about Hostakh

Cozy house He has its own smells characteristic of him - fresh linen, cookies in a brass closet or freshly sauced tea. Agree, in such a dwelling is pleasant. But not all the flavors want to inhale constantly. How to regulate the smell in the house? Everything is simple - need good exhaust for kitchen.

If the plate in your home is used not as an element of decor, but for a direct purpose or there is a grill, you probably have already wondered - how to choose a hood for kitchen? Today, manufacturers offer a lot of options for this equipment, and to choose the optimal one, you need to figure out which technique is needed, what power and how does the installation kitchen Extraction. About everything in order.

Kitchen hoods are installed in each house for quite a long time and usually represent a small exhaust hole next to the sink. However, the natural extract may not work well efficiently or not work at all, for example, due to a blockage or repair of neighbors. Because of this, the smells and spent air are stored, rises, the well-being of household deteriorates, and it becomes uncomfortable in the room.

Tips for repair professionals in the house always include the recommendation of a reliable extractor device. Why do you need it? First of all, because the kitchen is one of the main rooms in the house, housewives spend almost half of the day on it, and even with a dense intense work schedule of all households, this room is always in demand. Cooking - the process is not the fastest, therefore it is best to take care that not only smells of preparing dishes are not only stood over the stove, but also clean air.


Often, the problem solve the overall ventilation in the house or ordinary ventilation. Polluted air with this approach is removed quite slowly, and cold and not always pleasant smells from the street comes to replace it from the open window. Therefore, it is better to choose and buy a device for air intake directly near the plate, namely high-quality hood. Partially we already touched these questions when the device was considered, but now we will stop more.

Question: Do I need an extract in the kitchen with an electric stove?
Answer: During cooking on the electric stove, no fewer odors and evaporation is created than gas. Effective extractor will remove unpleasant odors on time and maintain a comfortable and healthy microclimate.

Before you choose a hood for the kitchen, you need to figure out the classification of such devices. Types of hoods for the kitchen today are divided into several grounds. First of all, they are divided into several groups on such signs:

  • The size
    The main principle in choosing the size of such equipment - it should be wider than the cooking surface. If you decide which it is better to choose dimensions, you can be guided by the following calculation: Plate width + 10 centimeters at least. Ideally, the exhaust umbrella should be wider than the plates on 20 or more centimeters.

Question: What are the sizes of huts?
Answer: Today you can buy an exhaust umbrella with a width of 30 to 120 cm, so it is easy to choose a suitable plate suitable for plates from a pair of tens of centimeters to a meter inclusive.

  • Modes of work
    Kitchen exhaust equipment today meets with two main modes of operation: actually removal of contaminated air and recycling. In the first case, polluted air, fat and soot are removed from the room, in the second the exhaust air is driven through dirt and grease filters and returns back. There are extracts that work in streaming and in circulation mode.
  • Control
    The technique can be controlled as manually when the air purification process is activated when it is required, for example, during cooking, and with an electronic timer and ready-made work programs. The latter is most often used with constant and active operation of the plates.
  • Removal in ventilation
    This parameter defines the general attachment of the new device into the ventilation system at home.
  • Power
    Perhaps the second most important parameter after size. Power should be sufficient to carry out full air exchange at least once a hour, according to sanitary standards. A little further we will tell you how to calculate this parameter.

The list includes the most basic requirements from which you can start when choosing. But for the selection of suitable equipment, you need to take into account some more factors and consider all the most popular types of extracts.

For the kitchen today is often found in new homes. Such devices have been popularly due to aestheticism - usually they are mounted in the kitchen cabinet over the stove and look like a shelf of aluminum or stainless steel. Built-in design equipped retractable panelWhat significantly increases the air intake area. Depending on the initial size, such exhaust equipment can fully cover the plates with a width of 50 cm, 60 cm, 90 cm and more precisely due to the retractable panel.

Folded extract Most often has simple control and activated by opening the locking panel. This is a very convenient solution - during cooking or immediately after it you can run the operation of the device and quickly eliminate the smells, and then close it and not spend extra electricity.

The embedded hood is usually equipped with two engines and has high power - if the plate is located close (within a pair of meters) to doors or windows, such equipment can take air from the street or from the entrance, so it is recommended to provide the influx of fresh air during the work of the technique.

How to choose a built-in hood? Focus on the size in the unfolded form and power. In addition, the embedded hood for the kitchen will require a separate locker, so the installation should be provided in advance, better - at the repair stage.

Hood with a tap in ventilation

All types of hoods for a kitchen with an air duct are usually reduced to a system with a tap in ventilation. Such devices are the most simple, since they consist of an air duct that is connected to the overall air exchange system, filters and exhaust fan. Fixture filters use fairly simple, they need to be regularly removed and cleaned. Such models can be located both open and "hide" in kitchen furniture.

Hood without removal is called circulating. It is most often chosen, because equipment without an air duct to install is much simpler - the design without a pipe is easily mounted, takes at times less place and organically looks in the interior.

The hoods without removing the air with a coal filter can only work in air circulation mode, delaying the smallest particles of fat, dust and smells. Such work quite noisy, so before buying it is worth testing the coal hood without a pipe and evaluate the noise level, since it will have to hear it quite often.

If in force constructive features Or other reasons for you only this option is available, it is worth installing circulating equipment, as it is still better than the kitchen without an exhaust.

The kitchen is the only room in the apartment where air is periodically polluted and a specific nasty smellassociated with the cooking process. Credit with this problem will help the kitchen extractor, which can be purchased at any store household appliances. The article provides information on how to choose an exhaust to the kitchen: the advice of professionals, characteristics of devices and overview of manufacturers.

Effective exhaust work depends on certain criteria that need to be considered when choosing a specific model. The quality of the device depends on its performance. Properly selected extractor can provide a six-time or tenfold air exchange in the kitchen. Best models Techniques have powerful fans that are capable of working in 2 or 4 speeds and effectively remove contaminated air. The umbrella of the working surface of the drawing must completely cover the cooking surface.

An important parameter when choosing an exhaust is a low noise level during its operation. For this purpose, select devices with an indicator of noise up to 45 dB. Noise when working such models will be similar to a quiet conversation, which is coming from a distance of 10 m.

It is necessary to give preference to the hood equipped with a high-quality lighting system working area using halogen or lED bulbslocated on the device panel. Decide which hood is better, it will help to study all the advantages and disadvantages of each specific type of device.

Types of Extrazhkov

First of all, you should decide on the type of device housing. Modern manufacturers produce draws of the following types:

  • suspended;
  • dome;
  • domino;
  • island.

What kind of exhaust to choose for the kitchen? Customer reviews give preference to the traditional version - suspended hood, which fits perfectly in modern design Kitchen. The case of the device is attached directly above hobs under the cabinet. It is easily mounted and has a relatively low cost. However, the suspension hood has a low performance due to the fact that the device operates in air recycling mode. It is ideal for small cuisines with an area of \u200b\u200b6 square meters. m.

Dome, or fireplace, hood has the shape of an umbrella and is attached directly to the wall. Its independent installation does not cause any difficulties. This type of household appliances has high performance. Among the rich assortment different options Hoods can choose the most suitable model, depending on the price, which perfectly fit into the kitchen design. Such extracts can be horizontal or inclined.

If you don't want to spoil the kitchen interior with an overall hood, then you can choose the type of device that is attached directly inside the kitchen furniture.

Modern type of drawing, which is very popular since 2016, is domino. Such a device is installed in the tabletop and extends from it when the electrical or gas stove is operated. However, the cost of such a trendy design is 2 times higher than that of alternative options. In addition, this type of device has a small productivity, which is suitable for small kitchens.

The ideal option for the kitchen-living room is a ceiling extractor, which is placed above the kitchen island. Such a device has impressive dimensions and has high performance.

Device performance

Select a specific exhaust model must be based on the total area of \u200b\u200bthe room where it will be installed. The device must have the required performance to effectively remove the polluted air into the ventilation shaft. To determine it, the area of \u200b\u200bthe room is to multiply to height and the resulting volume is multiplied by the coefficient 12, which corresponds to the number of air updates in the room.

The resulting performance is minimal. Therefore, the hood should be selected with some productivity reserve.

Exhaust size

The extractor is selected based on the size of the electrical or, above which it will be installed. However, so that the polluted air does not cost the fan, the width of the exhaust panel must slightly exceed the width of the plate. Today manufacturers produce extracts with a width of 45 to 90 cm. The most popular are models with a width of 50, 60 and 90 cm.

Principle of exhaust work

According to the principle of operation, the hoods without removal of ventilation (recirculation mode) and with an air vent in the ventilation system are distinguished. Hoods B. a private house Usually choose with recirculation mode to additionally do not mount the air vent. Therefore, the exhaust price for the kitchen without removal into ventilation will be much lower than the standard device with air tension and will be an average of 2.5 thousand rubles. Such models have low performance due to the fact that simply create air circulation, taking, cleaning and feeding it back into the room. For apartments, where there is a ventilation system, the most acceptable is the hoods for the kitchen with the air vent.

The flow hood passes polluted air through the filtration system, where it is cleaned from the oil evaporation and surplus of the soot and takes it into the ventilation shaft. The extractor is installed near the vent hole, connecting with it the air duct.

Helpful advice! The air duct must be as short as possible so that the air-cleaner device worked quieter.

Due to the fact that polluted air is excreted into the street, there is no need to purchase a hood with a tap, with a coal filter. It is enough so that it has a simple metal fat filter to prevent particle and fat particles in the ventilation shaft.

The main advantages of the flow hood are:

  • high device performance;
  • durable fat filters;
  • low noise.

Disadvantages of the device:

  • the extract takes the air, the disadvantage of which it is necessary to compensate for air from the street, in winter - cold, and in the summer - hot;
  • if the cooking surface is located far from the ventilation mines, the complex mounting work By setting the exhaust.

Extracts operating in recirculation mode are passed by air through an inner coal filter, then return it back in the purified form into the room. Coal filters after contamination are utilized.

The main advantages of the hood with a coal filter without removal:

  • recycling hood is mounted below hinged cabinet and leaves it free from the ventilation channel;
  • the principle of operation of the device allows you to maintain heat indoors, rather than throwing it into a ventilation mine, which is happening when the exhaust is operational with a tap;

  • you can buy an exhaust with a coal filter without removal at a lower price compared to the standard ventilation device with a tap of air;
  • installation of the hood is very simple and does not require special skills.

The main drawback disadvantages for the kitchen without aircraft:

  1. The operation of recycling hoods is more noisy than standard devices.
  2. Every 3-5 months, depending on the intensity of the drawing, it is necessary to change the filter material.

Helpful advice! If there are doubts about choosing an exhaust on the principle of operation, you can purchase a universal model that combines two modes of operation of the device.

Filtration system

By type of filtering system, single-stage and two-stage air settings and extracts of the first and second level are distinguished.

In single-stage systems, a single disposable or reusable filter is used. In the first case, it is thrown after clogging, and in the second only the inner cassette changes. With a two-step cleaning system, in the first stage, the air is filtered from fat, and the second stage ensures its cleaning from unpleasant odors. The filter of the first stage is often changing, and the second remains for a long time workable.

Filtering air systems of the first level can be acrylic or metal. Their cleaning is reduced to a simple flushing. Higher efficiency is the filtering extracts of the second level, where the coal filter is used.

Each exhaust model is equipped with a filter that protects the ventilation shaft from the soot. These can be metallic, synthetic or coal filters.

The metal filter is a foil or aluminum grid. They are easily clean, even wash in a dishwasher. Such a grease filter is able to serve the entire exhaust life, without requiring replacement.

The grease filter from synthetic fibers allows the device to work almost silently. Such a cleaner consists of a cassette in which the filter material is inserted: phlizelin or syntheps. When the filter layer is contaminated, the cassette is removed and installed new.

Coal filters provide thin cleaning air from contamination and smells. Its composition, in addition to activated carbon, can include cation, silver and other disinfecting elements. The main disadvantage of such a filter is its high cost and a small life. It requires a regular replacement after certain period Services that is 6-12 months, depending on the thickness of the coal powder layer. You can buy a fatty filter for drawing at a price of 1.5 thousand rubles.

Helpful advice! The coal filter perfectly absorbs the tobacco smoke.

Today manufacturers produce budget models in which there is no fat filter for exhaust. However, it is necessary to take into account the fact that such devices are not durable. Since particles of soot and fat will gradually settle on the fan blades, which will soon lead to his breakdown.

Device management type

By method of control, all modern models of extracts are three types:

  • sensory control allows you to control the operation of the device using a light touch to the desired sector, as a result of which the LED lights up and the extractor executes the specified command;
  • button control is the most familiar and standard. Here, each button corresponds to a specific mode of operation of the device;
  • pseudo-seensory control is carried out using a mechanical slider that is installed in the required mode of operation.

Types and advantages of devices. Choosing equipment. Calculation of fan power. Recommendations for independent installation.

For those who want to manage the operation of the device at a distance there are extracts with remote control, which is carried out using the remote control.

Exhaust material manufacturing material

Daily exhaust care and the price of the device depends on the material of the manufacture. Modern hood for the kitchen, photos are clearly confirmed, can be made of aluminum, plastic, stainless or enameled steel and tempered glass.

The most popular and inexpensive are aluminum hoods. A device from such a material does not require special care. However, it has unattractive appearance. Morethetical and stylish are stainless steel hoods. However, such models are more expensive and demanding in care, because they are polluted even fingerprints. Holding from tempered glass are the most expensive option that requires labor-intensive care. But these devices are the most attractive, which can make the design of the room unique.

How to set a hood in the kitchen

How to set the hood over gas stoveSo that she worked with maximum performance? The main time when installing the device is the definition, at what height should sweep the hob of the hob. If it is installed too high, its work will be unsolved. So, all odors and pairs will be indoors. With too low, the device will be interfered when working at the cooking plate. The optimal height of the hood over the gas stove should be 75 cm before its bottom panel.

The next point that affects the performance of the exhaust work is its location relative to the ventilation hole. The device must be located as close as possible to it to eliminate the use. large number Knee and pieces of aircraft pipes, which significantly enhances the noise and reduces the performance of the drawing. After connecting the exhaust with the ventilation channel, it should be worried that it is completely blocked. For this, special lattices or valves are used.

Helpful advice! The diameter of the air duct should be a little more outlet hoding. This will significantly reduce the load on the device engine and will allow it more efficiently working with a low noise level.

How to hang a hood over a gas stove

Mounting depends on the type of device. Flat hoods are mounted to the bottom of the suspended locker or directly to the wall using special hooks that must be securely hold it at the attachment points. The hoods with an angular plank are embedded inside the suspended cabinet, in which the hole for the air duct of the required diameter is predefined. Dome models are fixed on the wall.

After installing the filtering device, the duct canal is adjacent to the output hole, which is also fixed using hooks. As an aircraft, a corrugated or polyvinyl chloride tube with a smooth wall or a rigid metal or plastic box can be used.

Flexible corrugated pipe is the most budget option. However, it requires constant care the entire period of operation. Metal box is more convenient. But its installation requires considerable expenses. Optimal option PVC pipe is considered. It does not require special care and easily mounted. However, it must be installed strictly over the hood. Thanks to this recommendation m became clear how sdeat hood in the kitchen.

Kitchen Extras Rating

Before you think about how to better buy it to the kitchen, it is necessary to make a rating of global manufacturers of air-reading devices, which, in addition to the wide range of elite models of technology, offer equipment of the budget class. Many experts prefer such global brands like Siemens, Bosch, Kronasteel (Krona), Hansa, Gorenje, Elikor, Samsung. They successfully combine high quality, an acceptable price and an attractive appearance of manufactured products.

The exhaust of the German brand Siemens is the embodiment of conciseness and functionality. Such models have a low noise level, provide high performance, and an embedded type of body helps to disguise them to kitchen setAs you can see in the manufacturer's directories, in diagrams and photos. The exhaust price for the kitchen of this company starts from 12 thousand rubles.

Received world recognition, which confirm numerous flattering reviews, Croon extract from the German manufacturer. The company produces 7 main collections of cleansing technology. The entire proposed model range has high build quality. It is installed low noise, powerful engines that ensure high device performance. But, despite this, the cost of hood for KRONA kitchen is minimal and starts from 3 thousand rubles.

German Hansa exhaust technique is compact and convenient to manage. The functional model of this manufacturer can be bought at a price of 2.5 thousand rubles.

The demanding buyer who is not used to save on quality, to the question of what kind of kitchen hood is better, firmly chooses the German manufacturer Bosch. This is a serious high quality technique, the design of which corresponds to the latest fashion trends. The price of the kitchen hood is within 5-35 thousand rubles.

One of the best russian manufacturers Extracts, elikor is considered. Hoods, reviews about which confirm high quality techniques are represented by a wide model range of various designs, design and colors. Buy Elycor Extraction can be paid from 2.5 to 30 thousand rubles.

SAMSUNG brand technology is associated with high quality and durability of products. Modern models Do not cease to surprise the buyer technical perfectness and new functional characteristics. Standard model This brand will cost about 6 thousand rubles.

Gorenje ranks 7th in the ranking of the best world brands for the production of household appliances. It uses innovative approach and environmental materials in the development and creation of new models that are able to satisfy any customer request, which is reflected in numerous reviews. What hood is better to buy in the kitchen to get reliable protection Rooms from fat, dust and soot for a reasonable fee? The hood of the brand Gorenje will take care of the clean and fresh air in your kitchen. The price of the kitchen hood is 3.5 thousand rubles.

This article told in detail how to choose a kitchen hood. It turns out that it is not so difficult. It is important to competently explore all the advantages and disadvantages of each specific model and among the wide range of devices to choose perfect optionwhich is able to satisfy all your requirements and requests. Only then can be obtained a reliable assistant in the kitchen, which is capable of cleaning the air from harmful impurities and unpleasant odor.

Properly calculated performance and drawing power solve much more problems than we think. Unpleasant odors Burning, inevitable evaporation from heating devices, hated falling on the walls and ceiling of the kitchen and much more solved with the help of an exhaust. Add clean air to this (which is important for allergies, for example), saving money from frequent cosmetic repair premises and furniture (from humidity) and time on general cleaning (from the raid). By connecting all the components, you understand how it is important to choose the right hood that is suitable for you.

What you need to know first when choosing an exhaust:

- Connection method: It is important to know if you have the opportunity to connect the exhaust to the external ventilation channel of air purification. If there is such an opportunity - excellent, polluted air will be easily removed beyond the space. If there is no such possibility - it does not matter, the air will clear the special filters that are embedded in the hood.

The Council from the Ommin: - there is a delusion that the kitchen extract must provide full ventilation in any conditions. This is not entirely true. The efficiency of the kitchen exhaust is directly dependent on the type of installation and organization of air flow. Remember! The kitchen extractor is an integral part of the ventilation system, but does not replace it completely.

- Hoodry dimensions: When choosing a hood for a kitchen, it is necessary to take into account the ratio of the cooking panel and kitchen hood. Remember the main rule: take a hood with dimensions no less than the cooking surface. Then the leakage of polluted air turns out to be minimal. If you neglect these parameters, it is possible to reduce the efficiency of removal of evaporation and combustion products.

- type and size of the room (Isolated kitchen, kitchen-studio, kitchen-living room, ceilings height, indoor ventilation system, etc.): knowing these parameters, you can calculate the performance (power) and the noise noise level, thereby ensuring itself and its close-up kitchen.

The Council from the Ommin: - there is an opinion that in a small kitchen, say 6-9 sq.m., is quite the most primitive exhaust. However, in a small room, the smells and higher concentration of combustion products are faster, because the amount of their allocation does not depend on the size of the room.

How to calculate the performance and exhaust power:

When calculating the performance of kitchen hoods, the complete confusion is still observed. Starting with the fact that different manufacturers indicate the parameters of their devices obtained different ways. Someone declares the "naked" performance of the turbine, someone writes the real measurements of a particular model. Serious companies in their catalogs indicate all possible parameters in all types of tests (additional information can be requested from managers in the OSMIN store), and as the main one is the parameter with a free air flow for each model.

Classical power calculation formula:

Where P is the desired minimum drawing performance (m3 / hour); V - Kitchen Square; H - the height of the ceilings; 12 - Optimal air exchange per hour.

Firstly, Figure 12, National SES in the kitchen premises (12 times per hour), which will allow you to get the necessary performance for your room at the maximum (!) Hood speed, which means that you do not have a power reserve for emergency situations. In addition, the extractor on this power will work in the noisy mode itself.

SecondlyIf the hood is drawn to the air vent, then the power reserve coefficient is 1.3, and if it purifies with coal filters, then 1.5-1.7. Filters, catching fat and smells, have high resistance to air flow, therefore the power reserve coefficient is higher.

Thirdly, Calculation coefficient can still change depending on the type of cooking surface. Thus, for electrical cooking surfaces, a coefficient of 1.5 is needed, and for gas 2.0 (since in this case, in addition to evaporation from cooking, the products of the gas itself are also present).

Thus, for the kitchen of 3x4 meters and the height of the ceilings, 2.7 meters with an electrical cooking surface requires a hood with a minimum capacity of 486 cubic meters / hour, and with gas - 648 cubic meters / hour. For comfortable use in medium modes and availability of productivity, we recommend 600 and 800 cubic meters per hour, respectively.

FourthThe calculated area is worth using the boundaries of an isolated room, that is, limited by walls, doors and windows. If the kitchen does not have a closing door or it is not used, then to calculate the area it is necessary to take into account the size of the adjacent room, not separated from the kitchen. In cases, if the kitchen is combined with the living room, the dining room requirements increase dramatically due to the very rapid spread of odors and evaporation into adjacent premises, because they automatically become the kitchen premises.

So, summarize how to correctly calculate the power of the drawing:

Given: Kitchen 3 * 4 meters, with ceiling height 2.7; family of three; Electric cooking panelwhich is prepared three times a day. There is an air vent.
A task: Find an exhaust suitable
Decision: (3 * 4) * 2.7 * 12 * 1,5 \u003d 583.2 cubic meters / hour

On average, the performance of the extract you choose should be at least 600 cubic meters per hour., It is as much as it can move the air cubic meters per hour in your room. Congratulations! This is the performance of medium exhaust in the most common price category. The choice is huge here and in shape, and in color, and at the price.

What you need to know additionally about hoods:

Pay attention to the additional functions of modern hoods for the kitchen: what light bulbs will illuminate your work surface above the stove; whether there is a residual stroke of the fan that allows you to completely clean the air after completing cooking; Is there an interval inclusion of an exhaust, it is sometimes called "24 hours mode" so that the tide of fresh air into the room does not stop and contained the air in your kitchen clean. Timer, air ionization, online recipes, designer lighting, work with a remote control or launch from a mobile device - every year there are more technological models.

Design of the room and kitchen furniture: It is of great importance when choosing a kitchen hood. Pay attention to the design of the exhaust, the method and place of its attachment, the materials used, the color execution, what kind of cooking panel you have and what type and size is chosen.

Your habits and lifestyle: when choosing an exhaust, consider you a lot of family, as often and many you cook food, the presence of allergies, animals, children smoking indoors and others. Because all this information will help you choose the device for your family and For your home.

Now you can independently choose a kitchen hood from the Assortment of the company Ouxmin. If you have any questions - call or ask us online. We will definitely help you buy a hood for a kitchen that you need.

In order for in the kitchen, it was comfortable to cook dishes, and then eating food, you should take care of high-quality ventilation of the room. Our apartments provide common ventilation channels that are partly saved position, but are usually not effective enough. And then it is possible to "invite" a hood to the rescue - a special device that will forcefully remove the polluted air out of the room.


How to check what is needed

You can do one way:

  1. Lower a burning match to the vent hole, look at the flame. If it is deflected towards the ventilation channel, it means that the thrust is present, although it is impossible to just judge its level on its level.
  2. Applied to the opening a regular A4 paper sheet. If it lipnets, it means that the air out of the room is pulled out quite effectively. Otherwise, the need for extractor is very high.


Select the device

For what criteria you can make a choice:

  • external data;
  • dimensions;
  • the form;
  • principle of operation;
  • performance.

Perhaps the most valuable is just the last parameter. After all, it determines the effectiveness of the output of polluted air from the kitchen. And then the question arises, how to determine the necessary performance so that the process is as productive as possible, and staying in the room is most comfortable.


About productivity

To find out what device performance requires, it should be determined minimum powerwho must have a device.

Performance is calculated, without contact with the air vent. This parameter can be found in the instructions for the device, where it is indicated by the FB parameter, which means Free Blow.

In general, productivity is considered to be adjusted to the installation of the air ventilation of a particular section and length. As a result, the data are obtained that are closest to real indicators. This option is determined by the IEC 61591 standard. With this method of determining performance, the indicator turns out slightly lower than when FB. It should be noted that mainly manufacturers indicate both indicator instructions.

In some cases, performance data in recycling mode is also given. This data is even lower. After all, the performance is reduced due to the passage of air filters, overcoming barriers.

Performance is determined in cubic meters per hour.

Section of ventilation channels

In most cases, for calculating the power (performance), it is proposed to calculate the volume of the room and multiply it to the desired coefficient. As we found out, this figure may be somewhat inaccurate. This is confirmed by feedback.

Therefore, let's try to make power calculation, given the section of the ventilation channels. In most of our apartments, the diameter of the channel 140 mm is used or a square cross section 130x130 mm. Through such an air vent will be able to pass up to 400 m 3 / h. Of course, this is the perfect indicator. But there are still irregularities of the canal, bends and other obstacles that worsen the permeability.

If the extractor will work in circulation mode, the calculation can be performed based on the volume of the room. The calculation formula may have this kind:

where P is the desired productivity of the exhaust device, M 3 / h; K1 is a permanent coefficient that determines the desired amount of air change cycles per unit of time - in one hour, most often taken equal to 12; K2 is a reserve coefficient that takes into account the number of floors of the building, the resistance of the ventilation channel, contamination, and so on, is taken equal to 1.3; S - Kitchen Square; H is the height of the ceilings.

Now consider different variants calculations, given the difference in the area of \u200b\u200bthe kitchen: 6, 9, 10, 11, 12 square meters. m. - the most common options we have. By default, the ceiling height is accepted 2.7 meters.

  • 6 sq.m. - In this case, this calculation is carried out: 12x1,3x6x2.7 \u003d 252.72 m 3 / h;
  • 9 square meters. m. - the formula will be of this type: 12x1,3x9x2.7 \u003d 379.08 m 3 / h;
  • 10 square meters m. - Productivity will be: 12x1.3x10x2.7 \u003d 421.20 m 3 / h;
  • 11 sq. M. m. - the calculation will turn out: 12x1,3x11x2.7 \u003d 463.32 m 3 / h;
  • 12 sq. M. m. - Calculate the greatest indicator: 12x1,3x12x2.7 \u003d 505.44 m 3 / h.

As you can see, the most economical option is obtained in the smallest kitchen - 6 square meters. m. But it is unlikely that this fact can be envied, if you imagine how you have to be sophisticated by residents, using such a tiny room as a kitchen.

Other options

Of course, the calculations of power (performance) are approximate. Ideally calculate such an indicator as performance, a rather complicated event requiring engineering knowledge and practice. Therefore, we focus on the recommendations, reviews and formulas. This will be enough to choose a good and efficient hood. The main thing is to remember that the resulting indicator is the recommended minimum value of possible power for these conditions.


If the quadrature or height of the kitchen ceilings differs from the above examples, you must insert your data in the formula. And then the result will be relevant.

Build a house or make overhaul In the apartment, without kitchen equipment, a suitable hood is thrown on the wind money. Soak from fire, fat evaporation and smells of the prepared food very quickly impregnate furniture and walls not only in the kitchen, but also of all rooms. In addition, clean air is a guarantee of health and good appetite!

The role of kitchen exhaust

Modern design solutions In the design of the kitchen consider the hood as part of the decor. Naturally, the integrity of the furniture and equipment ensemble pleases the eye, but still, its functionality should be the main parameter in choosing this equipment.

Exhaust kitchen fan must properly:

  • purify air from harmful combustion products;
  • prevent fat and soot to furnishings;
  • remove odors as much as possible;
  • do not create a lot of noise when working.

The execution of all functions is fully possible if the drawing performance is chosen correctly. Companies specializing in the release and sale of this type household appliances, offer numerous versions for kitchens, their power is indicated in the passport. How to find out which one do you need? This will help the calculator and simple, but accurate calculation.

Performance and power

These two concepts, although related closely, but this is not the same thing.

The productivity of the kitchen hood is the amount of air that it is able to pump through itself in one hour. It is measured in cubic meters per hour (m 3 / hour).

Power determines the amount of electricity that will be spent on the operation of the fan, lighting and other exhaust functions. This indicator is most likely to calculate efficiency. When solving the question "How to calculate the power of the exhaust", you should pay attention to both the maximum loads and the intermediate, when working in various modes. The most correct capacity calculation is the average.

The standard performance calculation formula looks like this: the kitchen area multiplied by the ceiling height and multiplied by 12 (air renewal coefficient adopted by sanitary standards), or (SXH) X12.

What affects performance?

A simple basic formula does not give a complete view of what exactly the extract will be needed in your case. In addition to basic indicators, it is necessary to correct the calculation, taking into account:

  1. Principle of work.
  2. Features location.
  3. Hood design.

How these parameters adjust the formula for calculating performance, consider in more detail.

Principle of operation and performance

With all the variety of structures, the principle of operation of the hoods comes down to two options: on the removal of air and on recirculation.

Work on air removal

In this case, the fan absorbs polluted air together with the soot particles and displays them outwardly on the ventilation channels. Since the air must be updated constantly, fresh air access is required for full cleaning.

Work on recycling

This way is cleared by air in the kitchen, if there is no possibility for removal. Kitchen evaporations pass through metal and coal filters and returned back to the room.

How do these indicators affect the calculator calculator? Usually, hoods with recirculation work have lower performance, higher noise level and require greater power. For fans with a discharge, the performance is adjusted directly proportional to the length of the air show.

Location and productivity

An increase in the efficiency is associated with the location of the kitchen air purifier and the area of \u200b\u200bthe indoor cleaned area. The fact is that the standard calculation involves closed kitchen space. In the event that the kitchen is connected to the living room or between the rooms of the doorway decorated with an arch without door, it is necessary to consider the total area of \u200b\u200bboth rooms.

Effective exhaust work is ensured if it is placed right above the cooking surface and slightly exceeds it in width.

Decisible SNiP The coefficient of air exchange 10-12 is also the value relative. Use hood economically allows an increase in the coefficient to 15 for electric stoves and up to 20 for gas cooking surfaces.

Estimated Calculators for Calculators for Calculate Calculations and Highway Performance are mainly offered standard forms. The more accurate will be the calculator in which you want to specify more parameters.

In any case, it is more expedient to buy a hood, which has a little more than the maximum required for you. This will ensure her work is not in full modeIt will reduce the power consumption and, accordingly, will prolong the service life of the device. Yes, the noise level is significantly reduced, which is important, especially with a long cooking.

What is better design?

There is no single answer to this question. Again, it all depends on individual features Kitchen arrangement.

Dome hoods

A large hood wardrobe in the form of a dome over the stove is considered at this time the most efficient. Such ventilation is appropriate in large kitchens, better with island accommodation of the hob.

Flat hoods

The traditional design of this type is very common in places where there are problems with the installation of the air output system. Basically, flat forms of ventilation devices are equipped with a filter system and operate on recycling and cleaning.

Built-in hoods

The form is reminiscent of dome, but less in size. The main part of the design is hidden into the locker, only the control panel and the main panel remain in sight. The most ergonomic option is usually the most low. But there are exceptions.

Little area of \u200b\u200bthe kitchen - not meaning a hood with a small productivity. In small indoors, with large volumes of work, the air is polluted much faster.

Let us sum up: the calculation of the necessary drawing performance is not difficult. With the help of the calculator, it's easy to cope with this. The only rule is an individual approach to this event, taking into account all the nuances.
