Plastic

Plastic pipes can have a rectangular or circular cross-section. The best option for the kitchen interior are rectangular products. However, according to experts, the most productive are exactly round ducts, because they have the lowest resistance to air.

No matter what type of duct you choose, you will need to buy several types of adapters. Look at the adapters that are installed on the outlet of the hood from the duct and on the adapters attached to the outlet to the ventilation. To fit adapters tightly, use a simple sealant.

Advantages of plastic pipes:

  • in such pipes there is a low noise level from the functioning of the ventilation system;
  • fat, soot and dirt do not accumulate due to the smooth surface;
  • product life is more than 10 years;
  • pipes from plastic do not need additional leaving;
  • due to the light weight of the structure, an auxiliary load on the exhaust device is not created.

Steel

Steel air ducts are made from galvanized and stainless steel grades. As kitchen products galvanized pipes have become very popular. It should be noted that this type of pipe becomes less popular every year.

Of the advantages we can note the following qualities:

  • surface smoothness. Due to this, dirt and soot does not get stuck in the pipes, and the air flow does not slow down as it moves through the pipes;
  • products are able to withstand high temperatures;
  • low price.

If we talk about the shortcomings of steel pipes, then these include:

  • heavy weight. Installation will require additional fasteners;
  • in order to seal the channels, it is necessary to additionally purchase special solutions;
  • if your duct has a complicated type of shape, you will need to cut the pipe;
  • loud noise when working.

Dimensions

To a variety of rectangular ducts include flat products. They attract with their compact size, due to which they are easy to hide. There are three standard sizes:

  • 110x55 mm. This size is used for work with an extractor with a capacity of no more than 300m3 / h;
  • 120x60mm Such a construction can miss more air, but not more than 350 m3 / h;
  • 206x60 mm. These products are the largest. Their installation is carried out to the hood with high performance, when you need a high level of air purification from smell.

It is best to choose a duct with the same or larger diameter than the output parameters from the hood. When using a pipe of smaller diameter, the ventilation performance deteriorates. Along with this, the noise level will increase, the exhaust motor will operate in an enhanced mode. These components will lead to rapid wear of equipment.

A minimum amount of bends should be present throughout the duct. With their presence it is necessary to observe an angle of no more than 90 degrees, since each angle lowers the performance by 10%.

The total length of the duct should not be more than three meters. Each meter reduces the efficiency of the ventilation system by 10%.

What is the difference between exhaust and ventilation

For residential premises there are certain sanitary norms that determine the air exchange in the room. To fulfill these requirements, every house must have a ventilation system that will be responsible for the air circulation. It is worth noting that this system is unsuitable for eliminating strong odor and smoke, because it functions on the basis of the natural exchange of air.

Only the kitchen hood can provide local air discharge. This design is installed in a room where there is an increased accumulation of unpleasant odors. Such equipment removes steam that rises from the surface of the stove and with the help of an air duct takes them into the exhaust duct from the general ventilation system. This is the difference between the hood and the ventilation system.

Today extracts are divided into several types:

  • flat;
  • built-in;
  • dome

Flat suspended hood is installed under the hanging cabinets or above the stove. Outwardly, they resemble the previously existing Russian air purifiers. Most manufacturers put in this equipment grease filter, which is made of acrylic fabric. Such filters are disposable and need to be changed periodically. Such hoods are gradually becoming a thing of the past, being replaced by modern devices with cleaning filters.

Connection Rules

Before you start the assembly of the duct, you need to determine the size of the future design. To implement the optimal selection of boxes, you must fulfill several requirements:

  1. The number of turns of the duct should be minimal, because each bend lowers the efficiency of the kitchen hood by 10%. Experts recommend installing no more than three knees.
  2. Make the air pipe collapsible, as it periodically needs to be cleaned.
  3. When installing corrugated boxes can be used as fastening ordinary clamps.
  4. Do not use a deaf type of fastening the duct to the ventilation grille. If the box fits snugly, then during the period when the ventilation system is turned off, the natural circulation is disturbed. To avoid this, it is necessary to install a special ventilation grille with a hole and a built-in check valve.
  5. Do not use channels of different sizes. You will need special adapters that reduce the performance of the system as a whole.
  6. The most attractive appearance have rectangular boxes.

If you are thinking about the question of how to combine the duct with the interior of the kitchen most harmoniously, you will need to competently hide the structure. There are several ways to do this:

  1. The easiest way is to place the pipes behind a wall cabinet. You can also position the structure behind the furniture or above it. This method is the most affordable.
  2. If your kitchen has a two-level ceiling, you can install the air duct between the levels. If there is a hinged ceiling, it is better to place the structure above it. In this case, the air path will not be visible.
  3. To hide the pipes, you can use a special type of rectangular box type. When experimenting with the color scheme in the interior and installing pendant lamps, you can significantly transform the kitchen. At the same time, you will retain quick access to the pipe if repair is necessary.
  4. Simple painting of pipes in a color that fits most harmoniously into the overall interior also takes advantage of relevance. With the help of modern materials you can fit the air duct into the interior of your kitchen.

Other methods:

  • by masking over the false ceiling. With such a ceiling, you can easily hide all pipes in a horizontal direction. A special casing is put on the vertical products, which is covered with the same material as the ceiling;
  • use a decorative box. Today in stores there are a large number of types of housing, which differ in shape, color and option. You can dilute the box spotlights;
  • if you install the air duct simultaneously with the purchase of furniture in the kitchen, you can install pipes inside the cabinets;
  • some owners are self-made drywall boxes. Coming from the interior of the kitchen, the whole structure is painted in the required color or glued with wallpaper.

If you are unable to make the required level because of the surface of the cabinet, which is installed above the stove, you will need to cut it a little. In most cases, you will be able to determine the height of the lower part of the hood using the device's motor. As a rule, the size is 0.5-0.7 meters.

These works can be started only when you removed the cabinet from the wall. To obtain a high quality surface, when interacting with hand tools, you need to observe an angle of 20-30 degrees between the working area and the surface of the cabinet. If this condition is not fulfilled, then chipped pieces will appear on the back, which will affect the aesthetics of the furniture.
