Ventilation deflectors: product description

At present, the use of devices such as ventilating deflectors is becoming more common. They are important in modern households. These devices are special attachments for strengthening traction by using wind energy inside the ventilation system. At the same time, they protect the equipment from atmospheric precipitation and wind pressure, as well as from the ingress of dust, leaves and other contaminants into the system. Also, in places where it would be necessary to create traction by mechanical means, it will be sufficient to install the deflector of the ventilation pipe.

Installation of the product

This device is installed at the outlet of the ventilation shaft at a distance of 1.52-2.5 m from the height of the skate of the building. It must correspond to the design calculations and drawings. Also, there are cases where it is possible to mount this device on a vertical riser or duct. To date, many different forms and designs of this aerodynamic device have been developed. The most common are two types:

• Ventilation deflectors TsAGI. They are located inside the exhaust shafts. They allow the best way to use the energy of heat and wind to create a zone of low pressure inside the cylindrical shell, which creates conditions for the operation of the exhaust system.
• Roof deflectors. These devices are located on the roof of the building at the outlet of the duct to remove contaminated air.

The attachment of these aerodynamic devices can be either a shroud or a rack. The choice depends on the exhaust shaft and the location of the equipment. This is important in this case. Ventilation deflectors are selected for a certain exhaust system on the basis of special calculations, which determine the type of the device, the location of its installation, as well as its overall dimensions and appearance. These calculations can be carried out independently, having certain skills, but it will be better to use the help of professionals in this matter, since the ventilating rotational deflector can not be installed without preliminary calculations performed by a specialist. After all, the operation of the equipment may have the following features: or the process will be too productive, which is not very good, especially for residential buildings; Or it will be inefficient, creating only an obstacle in the exhaust system.

Product Material

Ventilation deflectors are made of cold-rolled or galvanized steel. To prevent corrosion damage and extend the operational life of the equipment, the coating of the metal is carried out using paint and varnish materials. It can be a special enamel, a primer, a powder coating. The connection can be flanged or nipple. With timely and quality maintenance (cleaning from dirt and dust, renovation of the coating), these products can serve for decades.

Device characteristics

The main indicators that characterize ventilating deflectors are:

• Size of the diameter;
• Connection design (nipple, flanged);
• Wall thickness and height.

All sizes are calculated in accordance with regulatory documents (GOST, SNiPu). For these calculations, the characteristics of the installation site (private or multi-apartment buildings, shopping centers, sports halls) and operational characteristics (protection of the exhaust equipment from atmospheric precipitation) are used.

Tip

In order to more accurately choose a qualitative deflector, you should involve a specialist who will make the correct calculations, based on the location, weather conditions, wind load, as well as the necessary design.
