Ventilation vents: product description

Currently, the increasingly common use of accessories such as air vents. They are important in modern households. These devices represent a special nozzle to increase the thrust by using the energy of the wind in the ventilation system. At the same time they protect the equipment from rain and head wind, and from falling into the system of dust, leaves and other contaminants. Also in places where it would create thrust by mechanical means, it is enough to install the vent duct.

Installation

This device is Installed at the exit of the ventilation shaft at a distance of 1.52–2.5 m from the ridge height of the building. It must conform to design calculations and drawings. Also, there are times when it is possible to install the specified fixture on a vertical riser or duct. To date, developed many different forms and designs of this aerodynamic device. The most widely two types:

• Vent deflectors TSAGI. They are placed inside the exhaust shafts. They allow you to make the best use of the heat energy and wind to create a zone of reduced pressure within the cylindrical shell, which creates conditions for the functioning of the exhaust systems.
• Power Roof vents. These devices are placed on the roof of the building at the exit of the duct to remove contaminated air.

Joining these aerodynamic devices can be as binding and rack. The choice depends on the exhaust shafts and the installation of the equipment. It is important in this case. Air vents are selected under a certain exhaust system on the basis of special calculations, which determine the type of a specified device, its mounting location, and its size and appearance. These calculations can be carried out independently, having certain skills, but it would be better to take the help of professionals in this business, as the rotary deflector vent cannot be installed without preliminary calculations has been carried out. After the work equipment may have the following features: or the process is too productive, which is not very good, especially for residential buildings; or it will be ineffective, only creating an obstacle in the exhaust system.

Product Material

Ventilation vents are made from cold rolled or galvanized steel. To prevent corrosion damage and prolong service life of equipment carry out the metal coating with paints and varnishes. This can be a special enamel, primer, powder coating. A Connection can be flanged or threaded. With timely and quality maintenance (cleaning of dirt and dust, updating of the coverage), these products can serve for decades.

Fixture Features

The Main indicators of ventilation vents are:

• Diameter size;
• Coupling (nipple, flange);
• Wall thickness and height.

All the dimensions are calculated according to regulatory documents (GOST, SNiP). For these calculations use the characteristics of the installation location (private or apartment buildings, shopping centers, gyms) and operational characteristics (protection of the exhaust duct from rain).

Tip

In order to more accurately choose a quality vent, you should engage a specialist that will make the correct calculations, based on the installation location, weather conditions, wind loads, and required design.
