What are the plastic boxes for ventilation?

Each modern apartment has natural ventilation, which is carried by a common ventilation duct passing through all floors of the building. Very often there are dishes with ventilation ducts in the corner. Room design in this case should be properly designed so that this element was almost imperceptible, and fits perfectly into the overall concept of the interior.

ventilation system capacity is often insufficient to provide the required air exchange in the room. This applies particularly to the kitchen. For organizing a favorable and healthy indoor climate with high humidity it is important to arrange a forced ventilation system. It is able to continuously clean the air of smoke and odors, which are formed as a result of cooking. This system consists of a drawing and a metal or plastic the vent channel. It is connected to the ventilation duct in the kitchen.

It is important that the common channel regularly worked. Otherwise, to provide efficient ventilation in the apartment will be required to restore the ventilation ducts. Which will require additional costs for the involvement of specialists. Efficient operation of ventilation system depends on properly chosen and competent drawing duct installation.

Ventilation ducts vary in the manufacture of the material, size and shape of the cross section, the degree of flexibility and elasticity. The most popular arrangement for domestic ventilation systems are considered plastic ducts. Unlike bulky galvanized ventilation ducts, they may successfully complement any kitchen interior. They are made from high polymer materials such as polyethylene, polyvinyl chloride, and propylene, without harmful impurities to human health.

The ventilation system of the plastic boxes are very easy to mount on the principle of tube-socket. With such a simple circuit structure compounds can then be easily disassembled for maintenance and cleaning and reassembled. The number of cycles is not limited.

Among the wide range of plastic moldings can choose the desired composition of the components with which pave duct of any shape and length without the use of welding machines, devices or rollers soldering. Numerous photos on the Internet show you how to beat a duct in the kitchen, so it fits perfectly into the interior of the premises.

Due to the small weight of the polymer duct easily fixed to a ceiling or wall using conventional anchors.

If you want to collect a ventilation system that will collect and divert hot air saturated with vapors, it is advisable to use a duct made of galvanized steel. It is able to withstand high temperatures and not lose shape. The polymer box, on the contrary, can quickly become deformed and lose its tightness.

The polymer has good insulating performance, which reduces the risk of water condensate and reduces lubrication vapors of organic compounds inner surface of the plastic boxes. And due to the smooth, polished plastic surfaces provided smooth retraction contaminated air containing grease, soot, and organic compounds which do not settle on the walls boxes. These features reduce the risk of accumulation and development of pathogenic microorganisms in the ventilation system.

Features choice of polymer ventilation ducts for ventilation

Before you buy a plastic ducts for ventilation, should define the purpose, type and capacity of the ventilation system. Plastic air ducts are chosen on the basis of power extraction, the specifics of the layout and design of the room. The efficiency of the entire system depends not only on the correct installation of in compliance with all the basic criteria, but also on the correct choice of cross-sectional area and shape of the channel.

section tubes for plastic boxes is chosen based on the maximum amount of contaminated air that has to pass through the system at a speed of 3-7 m / s. This value must be equal to or slightly greater than the size of the outlet drawing.

If the section is chosen too large, running the ventilation system will create an extra buzz. In addition, it will lead to operate at a cash investment and complexity of installation.

In the case of a small section of the duct exhaust performance will be reduced due to increasing the load on the engine. This will reduce the air changes in the room, occurrence of vibration in the system and increase the cost of electricity.

The choice of form of ventilation ducts depends on personal preference and kitchen design.

Important!Round air ducts provide a quieter operation of the ventilation system.

Plastic fittings for exhaust

ventilation device should begin with the preparation of the drawing indicating the types and sizes of parts and elements of fastening points on the wall or ceiling. Depending on the design of the premises and the location of furniture airbox can have a different configuration. This is done using special plastic moldings, which are connected to the straight portions of the ventilation duct according to the "planting a side - bell."

Today, we can buy a ventilation duct of circular or rectangular cross section a length of 0.35 to 2 m. Cut the required length portion can be using grinder or hacksaw. If a straight portion of length greater than 2 m, it can be mounted by using multiple items of standard length, connecting them together by means of special elements for polymeric channels.

Rotation of the duct at 45º or 90º carried out by means of the knee. If you are using a rectangular box a change of direction can be performed both horizontally and vertically.

Useful advice!If the duct is necessary to turn the value is not a multiple angle 45º, you should use multi angle the knee, in which one of the parties, depending on the angle you need, cut.

If you want to change the shape of a box with a rectangular to circular, special adapters are used. Products can be straight or angular shape.

Manufacturers produce such kinds of transitions:

  • from 100 mm diameter to the size of the cross section of a rectangular duct 110h55 mm;
  • from 100 mm diameter to the size of the cross section of a rectangular duct 120x60 mm;
  • sectional diameter of 125 mm to a size of the rectangular duct 204h60 mm.

To make the transition to the plastic boxes of a different size, use reducers. Special universal adapter is used for polymeric products of circular cross section of any size.

Features a plastic box mounted to the hood

Installation of the plastic box is easy to carry out on their own, without the involvement of specialists. However, for the efficient operation of the system, it is better to use the services of professionals. When the installation is important to follow certain rules. First, the ventilation system to operate at maximum capacity, the length of the duct portion should be minimal. The optimal distance is the distance of not more than 3 m. It depends on the location of the ventilation duct, which is located along one wall or in a corner of the kitchen, and a location with respect to the hood him.

The most common option is the kitchen with a ventilation duct in the corner, this picture clearly demonstrates. Here, it is advisable to place the hood near the channel that will prevent the installation of long air lines and reduce power losses the exhaust device.

Second, to avoid creating excessive aerodynamic resistance within the system is desired use the minimum number of shaped elements for changing the direction of air movement flow. The larger the area to be set on knees 90º, the higher the resistance in the system that will create additional noise in the exhaust device. This will also result in excessive accumulation of grease and dust on the inner surface of the air ducts.

It should be remembered that the polymeric conduit have a low degree of fire resistance. Products can withstand temperatures not exceeding 50 ° C. Therefore, if it is necessary to mount the riser duct near the heating or other heat source should be routed therebetween insulation to prevent the irreversible plastic deformation.

Useful advice!To create a thermal insulation is best to use foam having low thermal conductivityWhich will not create additional noise under vibration of the plastic box.

Plots of the polymer to drawing air from the ventilation duct can be secured in different embodiments. It depends on their location relative to the walls, ceiling and cabinets. It should take into account all the nuances, to avoid the noise, vibration, deformation and sagging of the ventilation duct with the possibility of loss of pressurization.

Plastic box which is disposed inside the kitchen cabinets, attached to their back wall by means of clamps. Designated passing through the walls of the box are fixed by means of expanded polystyrene or foam inserts, which prevents occurrence of noise during operation of the system.

If the duct is located above the enclosure, its fixation is performed by means of special holders or small screws for wood. Fastening articles to the ceiling or wall occurs by means of holders disposed at a distance of 1 m from each other. Fixing is carried out using special clamps that are matched in size and shape of the ventilation duct.

If vent duct is closed or suspended stretch ceiling, it should be securely excluding visual perception of appearance design and test the reliability of the fastening system at the maximum hoods.

Useful advice!Despite the fact that all plastic parts of the ventilation system in close contact with each other, it is better to treat all joints with acrylic or silicone sealant, which prevents depressurization vent duct after a time.
