To enhance natural ventilation, additional devices are bought. For this purpose, centrifugal fans are used, which are used in different fields. Various characteristics of centrifugal fans allow you to choose the best option for yourself.
Centrifugal fans are significant in industrial and domestic ventilation systems. These devices have simple structural features. Fans of this type consist of a spiral case equipped with exhaust and suction holes, a drive and a working wheel, which are several blades located between the disks, worn on the shaft.
Rotation of the wheel at the entrance and output of the body creates the difference in pressure. Due to this, the movement of air occurs, which is affected by the centrifugal forces acting in the radial direction in relation to the body. As a result, the air flow is pushed out to the outside.
The main features of centrifugal fans, which indicate their effectiveness, are complete pressure and performance. Centrifugal fans are made with bent back or forward with shovels. The use of models with blades bent back helps to save electricity up to 20-30%. This quality does not apply to models with shovels bent forward.
On sale there are models of centrifugal fans with the right and left rotation of the working wheel. An electric motor connected to a working spatula with an elastic coupling sets it in motion. There are models that have a cellet transmission that can enhance the angular speed of rotation as necessary. These devices are characterized by a small level of noise and various design.
