Set aside the hot and humid air from the stoves will use forced air - extract, Connecting to a vent stack building. If space allows, or the location of the central outlet there, under the hood tube to the kitchen moved to the street. Anyway, to get in the kitchen room of normal atmospheric require installation duct, through which air is removed and.

Components of the steel duct for exhaust

classification extracts

Kitchen exhaust systems are primarily classified according to various criteria. Depending on the method of removal and cleaning of air there are two types of devices: intake, which is needed for access to the external atmosphere and to vent standpipe, and recycle, eliminating impurities, passing the air through a charcoal filter.

Extractor hood for the kitchen duct longer installed, and channels require masking. But the advantages of the increased cleaning efficiency and savings in replacement filters outweigh.

recirculation device, such as standard or sloping hood no air is quicker and easier. But not cheap carbon filters need to be changed every six months. Therefore, the choice is often made in favor of exhaust systems.

Another type of classification - drawing design. According to it, devices are divided into standard (traditional), dome, Built in and inclined.


Advantages conventional exhaust device of low cost and compactness. The device is suitable for a small-sized kitchen facilities. The rear part of the device attached to the walls, hood itself is located above the slab. And to increase the capture area of ​​the exhaust air equipment dimensions extend beyond the cooking surface.

Due to the dome shape of hoods removal of polluted air and fumes occurs most effectively. A disadvantage may be mentioned embodiment only bulkiness.

Dome extraction systems come in three types:

  1. Fireplace;
  2. Insular;
  3. corner.

The most common type of chimney hood dome was named because of the similarity with the venting system of the fireplace - air enters the body in the form of a dome and with the help of the duct removed the street or in a mine. The popularity of such extracts has provided a wide range of design solutions - different colors, inlays and other features, allowing to fit the model in kitchen interior.

Island hood is attached not only to the walls, but also to the ceiling surface, allowing you to set the cooking surface anywhere in the kitchen. Option is suitable for spacious rooms and is worth more than the rest.

Feature of the corner device - a special form, Allow a kitchen furniture with a duct in the corner. Disadvantages presented difficulties with the installation elsewhere while moving furniture and the lack of a large selection. Angle Suction device selected, guided not by aesthetic considerations, and in the case, when the other option is not available.

for installation in ducts mounted equipment to hide the hood in the kitchen, saving space and without violating the interior. Only visible panel, sometimes pushes forward to increase the speed vozduhootvedeniya. The advantage of option - to save on housing, does not require an attractive design. The difference in the cost of the traditional one - to 20 percent.

Hood built between the upper cabinets and kitchen furniture. The front part of the instrument panel is closed, suitable in style to the kitchen wall. Reduced compared with the installation in ducts efficiency of the heater is compensated by the reasonable price of equipment.

Optional built-in way to install the hood - mounting in the tabletop kitchen wall. Fence portion extends upwardly if necessary or located on both sides of the plate. Equipment design is usually made in the style of "Domino" - using black and white colors. Disadvantages - saving space above the stove turns costs extra work zone areas. Advantages - stylishness and originality. It is worth paying attention to the immediate, to climb to the top of the room, removing polluted air.

A method of installing the exhaust system at an angle to the wall is popular, thanks to conserve space and increase ease of use. Extractor is a powerful motor performance and venting, with near-silent operation. Disadvantage - increased price, comparable to the cost of an expensive dishwasher, and high electricity consumption.

installation of air ducts

After selecting the type and model of the kitchen range hood determine the need for air exhaust system. Recirculating models do without the withdrawal of the street or in a vent stack, for diverting devices will need to install a duct for drawing. In order to bring the kitchen hood must be connected to the ventilation system - with the help of corrugated, plastic or metal ducts, possess a number of pros and cons.

Selection of duct

Classify feeds for the size of the hood, form, material and hardness. Duct-section is round, rectangular and oval. Standard pipe diameters circular shape - 100, 125 and 150 mm. rectangular dimensions start with 55 × 110 mm, and end 60 × 240 mm.

Pictures can be used metal and plastic. A configuration or rigidity distinguish flexible (gofre) and hard ware. corrugated metal pipe is used for ventilation systems.

channels form depends on the dimensions of the kitchen:

  • round duct takes up space and is recommended for rooms with high ceilings;
  • flat and most discreet of all the variants of the rectangular channel is ideal for kitchens with low ceilings;
  • a square cross-section are used rarely, occupying more space compared to the rectangular products and having the same dimensions, that round;
  • oval pipes are suitable for large rooms. Resistance to air flow and the minimum noise value even when a large volume of air exhausted is small.

Installing the air for a rectangular cross-section drawing easier, since joining the device does not require an adapter. For mounting round and oval pipes are used additional fittings - except for a use of a corrugated pipe. Corrugation quickly attached to the exhaust and ventilation, does not require knee.

When installing a duct pay attention to the diameter of the drawing - the device outlet sectional area should not be more than the same parameter of the pipe. Failure to comply with the rules will increase air resistance in the channel and reduce its consumption. Insufficient duct sizes lead to increased noise load and rapid failure of. A large pipe would not provide the necessary traction. Therefore, the best option is for the same tube diameter and the drawing of the device.

When the device is important, and the length of ventilation channels. The distance from the hood to the common output or exit pipe on the take out within 3 m. Greater value reduces performance.

The angle of inclination of the duct must be obtuse, and the design itself - avoid bends and folds Bole 90 degrees, save cost. To prevent a return of exhaust air to the kitchen immediately after stretching will allow the check valve - the two flaps, permit flow in the direction of removal and do not allow to go to drawing.

Considering the advantages of plastic ducts, taken to the kitchen ventilation round or rectangular, mark:

  • low noise levels (comparable with the sound, publish an extract);
  • rectangular ducts and smooth because the walls do not remain dirt;
  • minimum air resistance;
  • light weight facilitates transportation and installation.

The disadvantages include the increase in the number of plastic fittings - L-shaped adapter. Price details above in comparison with corrugations.

Installation is simple and corrugated ducting is possible with their own hands. Adapters are not needed, the price is less, and fixing wires with clamps. The disadvantages include:

  • noise affecting as it does when you remove the air;
  • retained on the folds of the corrugated dirt.

To prevent folds, delaying and increasing noise pollution, the tube is stretched along the entire length. Particular attention is paid to the place of rotation.

pipe installation

When installing the Air Release Channel are advised to follow the rules, changing depending on the tube material. The configuration is taken into account in the second turn. A cross-section sizes have almost no influence.

Selecting the corrugated pipe provide the easiest installation option. Bought Bumps, proposed in the form of requiring stretching segments, Installation operate bends, taking into account the length of the channels and the location of the hood. Instead, only the presence of a significant number of screws required fasteners. Yokes, disposable on either side of the pipe, is connected to an exhaust device and ventilation (or derived on the outside pipe). Such a duct for the cooker hood is created on its own and without special tools.

Install vent plastic will not take a lot of work. Such plastic pipes Ventilation Kitchen sawn hacksaw, entering into the interior. Sealant is used to improve insulation. Difficulties with the pipe connection, usually not round, a rectangular shape, eliminates installation duct for exhaust via fittings, too plastic and light, but increase the cost of the work.

If you make a duct for drawing metal, installation is complicated. The assembly is carried out overlapping, sealing compound using glue. Fasteners require drilling holes in the walls - is allowed to use the sealant, but strength will be lower.

masking rules

Corrugated pipe hoods can be hidden inside the cupboard

To save a kitchen interior close properly corrugation of the hood. for example, hide vertical pipe via hanging cabinets or lay on top of kitchen units, if the horizontal structure. Allowed to hide ductwork between the hood and in other ways:

  • use plastic box for hoods in the kitchen;
  • to strengthen the channels of the lower level ceiling;
  • buy decorative airbox, made in the general kitchen style. for example, with spotlights, built into the design of. Variant simultaneously hide pipe (regardless of the diameter and cross-section), enhance the illumination of the kitchen and add to the original furnishings.

kitchen equipment market offers the opportunity to buy ready-made furniture with built-in hood. All tubes are hidden behind the wall elements, masking is required - but the high cost solutions.

Box to camouflage duct can replace decoration products with their own hands. Rectangular or round duct (but not corrugated) paint color, blending in with the kitchen wallpaper, furniture and other interior elements, or cloth or paper okleivayut. Creative approach to the issue saves money and enhances the exclusivity of the premises.


A few more features masking:

  • buying a plastic tube for drawing together with the instrument itself, you can pick them up complete. Combined with each other tones Air Release design and equipment distinct look after installation;
  • corrugated channels acquire and after the purchase of equipment. They are in any case will have to put up with the mask or left on the mind not the most attractive part of the furniture.
