Many users will buy the wrong products because they don't know the difference between axial flow fan and centrifugal fan, and can't achieve the expected effect. So how to distinguish axial fan from centrifugal fan?
Axial flow fan and centrifugal fan are two different products of fan. Their main functions are ventilation equipment. They are distinguished from the following four aspects.
1、 Different appearance:
The appearance of axial-flow fan is cylindrical, and that of centrifugal fan is snail type. The motor connection of axial flow fan is generally in the body of the fan, and the motor of centrifugal fan is connected by shaft, which is generally outside the fan exhaust duct.
2、 The exhaust direction is different:
The exhaust direction of axial-flow fan is along the axis direction, the air inlet and exhaust outlet of the fan are on a parallel axis line, and the exhaust direction of centrifugal fan is perpendicular to the direction of air inlet.
3、 Different installation methods:
The installation of axial flow fan is relatively simple, which is usually directly installed on the wall or connected with the air duct. The installation of centrifugal fan is complicated.
4、 The difference of air volume and air pressure:
The air volume of axial-flow fan is relatively small, while the wind pressure of centrifugal fan is relatively large, there are many pipe elbows, the distance between exhaust and supply air is relatively far, and the pipeline resistance is large, so centrifugal fan must be used, such as the fresh air fan of building.
