Where are exhaust hoods used and how to install them correctly. Exhaust hood for the kitchen: principle of operation, design, types of units Classification of exhaust hoods

There are several traditional ways installation of wall and island ventilation hoods, which are designed to remove heat, smoke, moisture, odors from technological equipment installed in enterprises Catering, cafes, bars and restaurants.

The first method of installing an exhaust hood

The first method (the simplest) is installation of exhaust hoods to the wall using anchors. Depending on the length of the umbrella, two or three holes are drilled symmetrically in the rear vertical wall of the exhaust hood. Through enlarged washers with anchors, the exhaust hood is attracted and fixed to the wall. Wall in in this case must be solid and level, at least brickwork. If the umbrella has a large reach (more than 1000 mm), it is recommended to additionally attach the umbrella to the ceiling.

Second installation method

The second method is installation wall or island exhaust hoods through studs and collets to the ceiling. In the upper horizontal plane, along the edges of the exhaust hood, four holes are drilled or special ears are welded for studs, which include four studs Ф8 - Ф10 mm, pre-fixed in the ceiling. The method is quite simple and effective. The only inconvenience this method due to the fact that the ceiling height should not exceed 4350 mm, since the increased height will not allow the use of standard studs up to 2 meters long.

Installation of exhaust hoods on cables or chains

The third way is installation of exhaust hoods on cables or chains, through brackets and anchors to the ceiling. In the upper horizontal plane of the umbrella, four special fastening brackets are welded into which a cable or chain is fixed through a carbine, the other end of the chain is fixed to the ceiling. In this case, the height of the ceilings is not very important. Main possible problem When installing exhaust hoods using this method, it is associated with the instability of the structure. It is quite difficult to tie air ducts around a rigidly unfixed structure.

Installation of an exhaust hood using special support frames

The fourth way is installation of exhaust hoods using special support frames. Depending on the overall dimensions of the lower section of the exhaust hood, a support frame is made, on which the exhaust hood is installed on top. It can be rectangular or square shape on four legs, the height of which is selected individually for each object. The legs are rigidly attached to the floor through special support plates. Support frames are made from stainless steel profile 30x30 or 20x40 mm. Thanks to proven technology, the use of modern metalworking and metal-cutting tools, the specialists of the EuroVentGroup company achieve ideal geometry and a very presentable appearance of the exhaust hoods produced by the company and the supporting structures necessary for the installation of these exhaust hoods. In such cases where technological equipment located far from the walls, the ceiling height is quite high, and the customer has increased aesthetic requirements for the arrangement of the local exhaust ventilation the use of exhaust hoods complete with support frames from the EuroVentGroup company remains the only correct solution.

The Bastion ventilation plant offers its customers quality products, manufactured exactly on time. The company is one of the market leaders not only in St. Petersburg, but throughout Russia.

In this article we will talk about the use of exhaust hoods in various conditions.

Operating principle and varieties

In the kitchen of a modern housewife and in catering establishments, an exhaust ventilation hood or dome is installed. Its main task is to purify the indoor air from high humidity, odors, various impurities, the occurrence of which is associated with the cooking process.

The exhaust hood is component quality system ventilation in rooms. Installation occurs over sources high temperature, in particular, over stoves, cooking surfaces, open fire. The dome removes moist hot air, unpleasant odors, as well as soot, grease, soot, dust, chemicals.

Air purification from harmful impurities is also necessary in laboratories, chemical and industrial production etc., where manufacturing process occurs with the release of harmful substances into the space, which can harm workers and the environment as a whole.

The umbrella is a dome-shaped structure, hence the second name – dome. Connected to the ventilation system by an air duct. There are central (island) and wall-mounted, depending on the installation location.

Wall-mounted units are installed directly on the wall. If the weight is large, additional brackets are used for fixation. Central appliances are installed directly above the work surface, without contact with the walls. Island umbrellas have a large capacity.

A modern dome is not only a complex device, but also a decorative element. Factory capacity allows us to produce umbrellas in accordance with common interior premises.

There is no fundamental difference in structure between domestic ventilation domes used in private households and industrial ones; they are distinguished only by size and power characteristics. Umbrellas used indoors have a common structure:

• Grease filter. It can be mesh (made of a mesh with small cells) and labyrinth (a plate with grooves through which condensed fat enters a special compartment). The first type of filter is inexpensive, is installed only in a horizontal position, can be additionally equipped with a spark-extinguishing mesh, but requires frequent cleaning. The labyrinth grease trap is installed only in an inclined position and does not require frequent washing.
• Spark arresting mesh. Required element when installing ventilation domes over sources of open fire, for example, over barbecues, grills.
• Pendants. Part of a mounting system that allows you to mount an umbrella on a wall or ceiling, distributing the weight correctly.
• Turbines. The equipment is designed to stimulate the movement of air masses from the room. When installing, you must correctly determine the center work surface and domes to achieve maximum efficiency. The cross-section of the exhaust hood inlet must exceed the dimensions of the stove or other equipment over which it is suspended. The height of the suspension varies from 0.7 to 1.1 meters.

When choosing a manufacturer of an exhaust dome, give preference to domestic factories, so you can save your budget, and the quality of modern products from a reliable seller is confirmed by certificates and quality control.

Reading time: 6 minutes.

An exhaust hood is a necessary element of rooms in which the air is exposed to pollution. First of all, these are any kitchens, including restaurant ones, and chemical production. And the higher the intensity of pollutants, the better the air purification should be.

What is it and how does it work

The design of the umbrellas is quite simple. For example, a rectangular umbrella includes a main body, a tray for collecting grease and filters that perform a grease-collecting function. The tilt angle of the filters is 45°.

The chimney ventilation hood can also be equipped with additional elements: lamps, fans, connection ears, etc.

Design and principle of operation: hot air, formed above the thermal surfaces and having a lower density, rises up, is drawn into the hood and enters the pipe, where there are special grease-removing labyrinth filters. Fats from contaminated air masses condense and flow through special drain channels into the bath, and the purified air enters the air duct, which has a round or rectangular shape, through which it is discharged outside (in recirculation mode, the purified air is returned back to the room).

What are umbrellas made of?

The umbrellas are made of stainless steel with a high nickel content, which guarantees their long service life and the necessary strength. There are hoods made of aluminum and glass.

Specifications

When choosing an umbrella for the kitchen, you need to familiarize yourself with it technical characteristics. First of all we're talking about about him overall dimensions. The material from which it is made, its thickness and the mass of the hood also matter.

All necessary characteristics, incl. the effectiveness of air purification from aerosols is indicated in the passport.

Types of umbrellas

Based on the type of design, modular hoods are divided into island and wall hoods. Their air purification efficiency is approximately the same, but there are still some differences. For example, island structures have 2 rows of filters, which increases their productivity. They are attached to the ceiling and can be installed above equipment with large dimensions.

Wall hoods are mounted directly above cooking surfaces placed on the wall. They have 1 row of grease filters.

Both island and wall models can have different geometric shapes in cross section.

For equipment where open fire is used, grill umbrellas are produced that have complex shapes and are equipped with spark-extinguishing filters.

There is also an umbrella for the ventilation pipe, which has a mushroom shape and protects the pipe from precipitation.

Industrial

Exhaust and supply and exhaust ventilation hoods are widely used in industrial enterprises and catering outlets where they are installed a large number of thermal equipment (ovens, electric and gas stoves, combi ovens, deep fryers).

Among the industrial premises that need air purification are chemical and pharmacological laboratories. The task of industrial exhaust equipment is to effectively remove excess moisture, heat, harmful substances and odors and create an optimal microclimate in work areas.

Most often, industrial hoods are equipped with additional fans and lighting.

Household

Every self-respecting housewife prefers to have a hood in the kitchen, which purifies the air during cooking and minimizes room pollution (prevents droplets of oil, grease and soot from settling on walls, floors, dishes and other surfaces). A variety of exhaust hoods allows you to choose the appropriate model that will fit well into the interior of the room.

Types

To equip your food preparation area with a reliable hood, you need to have an idea of ​​what types of hoods are on sale. Manufacturers offer 3 types of hoods: flat hanging, dome and built-in. They differ not only appearance, but also technical characteristics and price range.

Built-in

The built-in umbrella is installed in the cabinet above the hob. This option is suitable for those rooms where it is necessary to preserve overall design. Neither the umbrella itself nor the bulky ventilation tube will not be visible due to hanging kitchen cabinet. Built-in hoods can operate in recirculation and air exhaust mode.

Flat

This is the most a budget option. The device is a flat case equipped with a fan and a replaceable filter. It works only in recirculation mode and is indispensable in rooms where it is difficult to install the hood in ventilation ducts, or where they are completely absent.

To the disadvantages flat type include: low power, high noise level and frequent filter changes (every 5-6 months).

Dome

Dome models are focused on 2 modes: air duct and recirculation. Their power is higher, which ensures their demand for large kitchens. The noise level they produce can be adjusted, and some hoods are equipped with remote control and a system for monitoring the level of filter contamination. Dome umbrellas are available in a variety of designs, colors and materials.

How to choose an umbrella

When choosing an umbrella, you should consider the size of the equipment over which it will be installed. There is a rule that the hood should overlap the hob by at least 10 cm.

The standard width of hoods is 50, 60, 70, 90 and 120 cm. Umbrellas of other sizes can be made to order.

The second point that you should pay attention to is the noise level of the exhaust equipment. The greater the power of the hood, the more noise it produces, and for humans a noise level of up to 40 dB is considered acceptable. Sound-absorbing devices, which manufacturers equip some models with, help cope with the problem.

Hoods are often equipped with lighting and act as a source of additional lighting for the kitchen.

If the hood will be installed high, it must remote control. The price of this equipment will be higher, but the ease of use compensates for the financial costs.

When choosing an umbrella for a chimney pipe, you should take into account the size of the pipe itself, because the head must overlap its edges. The umbrella itself can have any shape. It is also necessary to pay attention to equipping with additional structural elements(dropper, fixing parts and protective mesh).

DIY installation

A skilled owner can carry out the correct installation of the hood. For DIY installation in back wall For a wall umbrella, you need to drill 2-3 identical holes, first tighten it with anchors through enlarged washers, and then install it on the wall as close as possible to the air outlet for ventilation to the roof. The main thing is that the surface of the wall is smooth and durable.

The rectangular umbrella is attached to the ceiling using collets and pins, for which 4 identical holes must be drilled along the edges of the umbrella in the upper horizontal plane. It should be taken into account that if the ceiling height is more than 4 m, this technology cannot be used.

Cables and chains are used to install hinged exhaust hoods. In this case, the height of the ceiling does not matter. First, 4 brackets are welded to the upper plane of the hood. Then use a carabiner to secure the chain (or cable). Its other end is connected to the ceiling. All fastenings must be secure. The only “disadvantage” of such hanging, unfixed structures is the difficulty of tying them with air ducts.

It should be noted that umbrellas ventilation systems have absolutely no complex design. A rectangular chimney hood consists of a main body, a tray for collecting grease and filters that perform. Filters are always installed at an angle of exactly 45 degrees Celsius.

If we are talking about supply and exhaust hoods, then in this case it is necessary to use a grille or a device such as a diffuser.

In some cases, air duct umbrellas are equipped with additional elements, such as connection lugs, fans, lamps and many others.

1 Operating principle of the ventilation hood

This device works in the following way. The air that is subject to the processing process, as a result of which it becomes hot, has a much lower density, and therefore rises to the top, and is replaced by cold air currents.

Then the air enters the pipe and passes through special grease filters, where it is saturated with a large amount of oil vapor, due to which it begins to cool over time.

Ultimately, passing through such a pipe due to strong temperature changes, the oil condenses, air currents They begin to separate from it and through special channels allow the fat to flow into the bath.

In turn, the air, which is purified after such a process, enters the round or.

2 Device classification

Today, two types of rectangular umbrellas are used for chimneys:

1. Exhaust hoods . Their main purpose is the complete elimination of unnecessary gases, substances, and combustion products from the chimney. Highly heated air flows are drawn in by the umbrella, after which they are transported through a pipe where grease filters are located and are ultimately transported back to the air duct, through which they are removed from the building. All this can be easily done with your own hands.
2. Supply and exhaust hoods . Thanks to them, both the exhaust of polluted air and the supply of new air are ensured. clean air into the room. These umbrellas are best used in rooms where the flow of clean air is limited due to certain circumstances. It is always necessary to carry out calculations taking into account the fact that the volumes of supplied and extracted air flows will always differ from each other. Therefore, in no case should you count on the fact that exhaust hoods will contribute to the complete destruction of odors, gases and other substances. Although the chimney, of course, will work much more efficiently.

There is also a classification according to the type of construction. Thus, exhaust and supply and exhaust rectangular and round umbrellas are divided into island and wall.

2.1 DIY installation and calculation features

I would like to note that installing such umbrellas with your own hands is quite possible, since in fact there is nothing complicated in such work. Below are some of the most popular ways to install a chimney umbrella.

• Method number 1. Installation of wall-mounted exhaust hoods using anchors. After a certain calculation, the length of the umbrella is selected and 2 or 3 equal holes are drilled in the back of the wall. Using enlarged models of washers, the exhaust hood is first attracted and then installed on the wall. It is very important that the wall is perfectly level.
• Do-it-yourself installation of rectangular umbrellas through collets and studs to the ceiling. At the very beginning, you need to drill 4 identical holes for the studs. All these holes are drilled strictly along the edges of the umbrella, after which the device is attached directly to the ceiling. A modern chimney works perfectly if this option is used. The only negative is the calculation of the ceiling height to standard length studs do not allow the use of this technology if the height of the room is more than 4 meters.
• Installation of chimney exhaust hoods using various cables and chains through anchors and brackets to the ceiling. In order to do everything yourself, you need to weld 4 brackets of the required parameters to the upper horizontal part of the umbrella, and then use a carabiner to securely fix the chain or cable. The second end of such a chain or cable must also be securely connected to the ceiling. Among the disadvantages of this method, one can note the unsteadiness of the structure, so tying it with air ducts is not at all easy, but for a chimney this scheme is excellent.

As you can see, installing it yourself is not at all difficult. The main thing is to adjust the umbrella as close as possible to the chimney pipe and take into account some nuances.

Application area

Supply and exhaust and exhaust hoods of ventilation systems are widely used today by industrial enterprises and beyond. Such systems are widely used in public catering establishments, such as restaurants, canteens, bars, food factories, cafes, and so on.

Umbrellas are also installed over all kinds of heating equipment, in particular this applies to deep fryers, gas stoves, and ovens. If the calculations made allow the installation of such umbrellas, then they are used in various industrial premises - food, pharmacological, physical, chemical.

2.2 This is what a rectangular ventilation umbrella looks like - video

A necessary element of any serious kitchen is an exhaust hood. Such a device is required to be installed in industrial enterprises, but it also has a worthy place in domestic kitchens.

This hood option is exceptionally effective at removing cooking-related contaminants from the air. Let's take a look together at the operating features of this exhaust hood and the points that you need to pay attention to when choosing a hood for your kitchen.

A device of this type is a powerful hood designed for effective ventilation of air in kitchen area. They are most often installed directly above cooking surfaces in restaurants, cafes, canteens and other catering establishments.

Such a device can be installed not only above conventional kitchen stoves, but also over other similar equipment: grill, oven, etc.

The quality of dishes will only benefit from the presence of a good hood. Umbrellas trap water vapor, particles of oil and fat, and remove odors emanating from prepared dishes. All these contaminants rise upward under the influence of hot air and enter the working cavity of the ventilation hood. Here, the polluted air passes through a filtration system, where the purification process takes place.

Exhaust umbrella – stylish and modern device which will provide effective cleaning air in a domestic or industrial kitchen

Then the air masses, freed from unnecessary inclusions, are returned to the kitchen area or removed through the ventilation duct, depending on the type of device.

Fatty contaminants move through a separate channel and are collected in storage cups, from which they are periodically removed.

Grease traps are special aluminum elements that are installed inside exhaust hoods. They trap particles of fat and other relatively large contaminants

To facilitate the process of cleaning storage units from fat deposits, it is recommended to first pour a special detergent into the glasses that can effectively dissolve fat.

The advantages of umbrella-type exhaust structures include the following:

• the ability to use remote control;
• high degree of automation;
• possibility of installation suitable model in almost any area of ​​the kitchen;
• a wide range of different models made from various materials with an attractive design;
• high level of productivity.

Among the disadvantages of such equipment, the increased noise generation caused by the operation is primarily noted. powerful fan. For proper operation The unit should be serviced regularly, i.e. purchase and promptly replace carbon filters.

These items cannot be cleaned or refurbished and may cost more to operate than expected. In addition, good equipment of this type is quite expensive in itself.

An island umbrella can be installed right in the middle of the kitchen if the size of the room allows it. IN small room such a device can be placed above a stove installed near a window

Exhaust hoods are always necessary in the kitchen. Particles of fat, hot steam, soot, drops and other contaminants may not be noticeable at first glance, but over time they form various surfaces a layer of dirt that is not easy to remove.

In addition, gas residues that can enter the kitchen air and the smell of accidentally burnt food are also not good for the health of others.

The design of the ventilation hood is a steel dome-shaped housing, inside of which there is a fan and a set of filtration elements. A special aluminum grille is designed to collect relatively large particles, which protects the ventilation turbine.

In catering establishments, powerful exhaust hoods are required for use over cooking surfaces. Similar devices are used to remove harmful fumes in other industrial plants.

An acrylic filter is usually used to remove a significant portion of grease contaminants. In installations with recirculation, it is mandatory to use a carbon filter, which provides fine air purification. The spark-extinguishing mesh protects the elements from overheating and possible fire.

It is especially necessary if the umbrella is installed above the device with open flame. All filter elements must be periodically cleaned or replaced. Carbon filters are replaced as soon as they become dirty; these elements cannot be restored.

Some types of acrylic filters can be washed and reinstalled, but this treatment quickly causes them to lose their shape, so the number of cleaning and recycling cycles is limited.

The exhaust hood must be large enough to cover the parameters of the processed material. hob no less than 100 mm

A fan or ventilation turbine built into the umbrella ensures air circulation in the right direction with the required intensity. The performance of this element provides the total power of the hood, which should be correlated with the total volume of the room in which it will be installed.

Most umbrella hoods are equipped with lighting, which is very convenient. Such lamps can be used as additional lighting in the kitchen. Along with conventional incandescent lamps, halogen or diode lighting fixtures are built into hoods.

The latter provide a sufficient level of illumination with minimal consumption electrical energy and increased service life.

At industrial catering establishments, exhaust hoods are installed above the devices different types: stoves, grills, ovens, etc.

If the umbrella is connected to a house ventilation duct, it must be equipped with special valves, which prevent the air masses entering the device from returning to the kitchen area.

Types of structures and the problem of choice

Based on the type of design, there are wall-mounted and island-mounted exhaust hoods. The design can be exhaust or supply and exhaust. In the first case, the device only removes exhaust air from the room, in the second it also provides an additional influx of fresh air masses.

When choosing a suitable umbrella, you should consider required level air exchange, dimensions of cooking equipment, as well as the intended location for its placement. For an industrial kitchen, it is recommended to install a model whose dimensions are 100 mm larger than the dimensions of the hob.

For the manufacture of such devices they use stainless steel food brands. The device is usually equipped not only with a grease trap, but also with a carbon filter. Backlighting may be a useful option. Supply and exhaust devices, as the name implies, provide not only the removal and purification of polluted kitchen air, but also the influx of fresh air masses from the street.

Such umbrellas in living conditions used extremely rarely; this is a technique for professional use. Some operations require constant receipt fresh air. Umbrellas of this type allow you to create an exceptionally favorable microclimate in the workroom, adjust the humidity and air temperature to an acceptable level.

The power of the exhaust element usually exceeds the supply capacity in models of this type by about one third.

The advantage of using a range hood is that it can be installed in almost any suitable place, you just need to choose the right model

Wall umbrellas are mounted not on the ceiling, but on the wall. Typically, such models are used to connect to exhaust duct. To facilitate installation work, the hob is installed as close as possible to the ventilation duct.

In this case, it will not be too long, which facilitates the effective movement of exhaust air into the ventilation duct.

Wall-mounted hoods can be mounted on the wall. They are more convenient to connect to the building’s ventilation duct than island models

A short design usually does not require many turns when using rigid plastic ducts. There should be no more than three such elbows for one ventilation hood. The beveled type of island hood is very popular, which allows you to bring the hood closer to the maximum permissible distance to the hob.

An island-type umbrella, which is attached to the ceiling, is considered universal. As the name implies, it is used for installation above a kitchen island, specifically above a stove built into it. The peculiarity of the design is that when installing it there is no need to use a wall; the structure is attached to the ceiling.

Such devices are usually used in large kitchens, both industrial and domestic. In small areas, the use of a kitchen umbrella over the island is usually not used due to lack of free space. But such a design may be advisable even in a small kitchen if hob installed near the window.

The presence of two filters allows for sufficient air purification high level so that you can return it to the kitchen area. Of course, the necessary means should be used to ensure sufficient air exchange, but recirculation allows you to retain some of the thermal energy in the room that was spent on cooking.

To remove contaminated air using an exhaust hood, it must be connected to a ventilation duct. If this is not possible, use models with circulation and a carbon filter.

Recirculation is used in island hoods, since installing such a unit next to a ventilation hatch is usually quite difficult. Read about how recirculation hoods work. Some models of island umbrellas can be adjusted in height, which allows you to change the intensity of absorption of polluted vapors depending on the situation.

If the location for installing the hood is chosen in such a way that the filtered air cannot be discharged into the ventilation duct, then you will definitely have to give preference to a device with recirculation.

When choosing an exhaust hood for the kitchen, you should choose the right one. Most powerful option will do for kitchens up to 25 sq.m. m.

However, you should not choose a model with too much power reserve, since the higher the performance, the more noise the hood makes during operation. For small room this could be a real disaster.

There are exhaust and supply and exhaust hoods. The latter not only ensure the removal of polluted air, but also allow the influx of masses from the street to improve the atmosphere in the room

The noise level of the device is considered acceptable around 40 dB. It may be a little higher (up to 70 dB), but you should not choose an overly noisy model, since the sound of its operation can cause irritation. When choosing the type of control, you should take into account the installation height of the device. If the hood is installed high enough, the remote option can be very useful.

This equipment has a high price, so when choosing a brand, you should pay attention not only to the well-known name, but also to the warranty period, as well as the availability service centers and terms of warranty service. Of course, the design of the device also plays an important role. Fortunately, the models of exhaust hoods are very diverse, you can always find a suitable option.

Features of installation and operation

Installing this type of exhaust equipment is relatively easy, but inexperienced craftsmen are still better off entrusting these operations to professionals. If you decide to carry out the installation yourself, you should start with a detailed study of the manufacturer’s instructions.

Hoods are usually made from durable food grade aluminum steel. For industrial enterprises Such designs are often created to order

After this, you need to examine the installation site, take the necessary measurements, prepare tools, fasteners, materials, etc. Important point– correct distance from the hob. It must be at least 60 cm for electric stoves and 70 cm for gas appliances, but not more than 85 cm.

If the umbrella needs to be hung higher, then you should choose a more powerful device to compensate for the difference in height. To install a ventilation exhaust hood you will need tools that are usually in the arsenal of any experienced craftsman: tape measure and building level for marking; screwdriver, drill, hammer, etc.

Depending on the type of device, you will either need to simply hang it above the stove, or connect it with an air duct to ventilation duct. Either a metal corrugated hose or rigid plastic structures are used as an air duct.

The corrugation can be bent in a suitable way, and to make a plastic elbow, special adapters should be used to ensure a tight connection of individual sections of the air duct.

If the power cord is not long enough, you need to install an additional outlet near the device. You need to make sure that the electrical appliance has the necessary grounding.

Correct installation of the ventilation hood is only half the battle. For the device to work effectively, it is necessary to organize its operation. Detailed information on such issues is contained in the operating instructions supplied with each device.

Regular cleaning is of great importance. For example, aluminum grilles should be washed using special detergents. Good results can also be obtained by using products that can be found in any kitchen: acetic acid, diluted by a third with water, a saturated solution of ordinary laundry soap or a paste mixture of water and baking soda.

Aluminum grease traps for exhaust hoods must be regularly cleaned of accumulated dirt in order for the device to work correctly and efficiently.

These recipes will be useful for those who suffer from intolerance chemicals. Grates should be cleaned of accumulated grease and dirt at least once every three months.

Replacing carbon filters is usually done in the following order:

• disconnecting the device from the power supply;
• dismantling aluminum grilles;
• removing the used filter;
• installation of a new filter element;
• installation of aluminum grilles;
• connecting and checking the operation of the device.

When installing a new filter, you should hear a characteristic click. If, after replacing the filter, unusual sounds appear in the operation of the hood or it becomes noisier, the filter may be installed incorrectly and the work should be redone.

If cleaning and replacing the ventilation hood filters is not carried out in a timely manner, the performance of the device may significantly deteriorate.

Carbon filters are necessary in hoods with circulation; they provide fine air purification and need to be replaced regularly

Removable filters and glasses for collecting grease in umbrella models that are used in catering establishments should be cleaned daily in accordance with the instructions. It is also necessary to constantly clean the outer surface of the housing exhaust device. It is recommended to remove some elements and soak them in special cleaning solutions.

Once cleaning is complete, rinse them thoroughly. Another element that needs periodic cleaning is the air duct. It is necessary to remove the connecting elements and remove deposits from the internal surface of the structure.

Corrugated elements require this cleaning more often than smooth plastic channels. Some industrial models of kitchen umbrellas are equipped with a built-in cleaning system, but such expensive units are usually not used in everyday life.

Conclusions and useful video on the topic

This video shows the principle of operation of such structures:

An exhaust hood can ensure proper air exchange in both a conventional and industrial kitchen. Correct installation And regular care will ensure long-term and uninterrupted operation of such a device.
