Axial flow fan and centrifugal fan, this is the two types of fan. And also two common species, the main role, is the same, are used for ventilation. However, among them, there is a certain difference, which is mainly for:
1. Exhaust direction
The axial flow fan, its exhaust direction, is along the direction of the fan shaft, therefore, its inlet and outlet, is parallel, while the centrifugal fan, its exhaust direction is perpendicular to the inlet direction. It can be located at 360 degrees to exhaust air.
2. Installation complexity
Axial flow fan , its installation is relatively simple , and the installation of centrifugal fan is much more complex than axial flow fan .
3. Air volume and pressure
The air volume and pressure of the axial fan are relatively small, so to speak, it is basically no wind pressure, but for the centrifugal fan, its air volume and pressure is relatively large. Therefore, if the pipe bends are more, and the transport distance and pipeline resistance is large, the use of centrifugal fans is more appropriate.
4. Appearance shape and motor connection mode
The axial fan is mainly cylindrical, and the connection way of its motor is in the fan body, while the centrifugal fan is mainly snail like. The connection mode of its motor is connected by shaft, and it is usually outside the fan.http://www.jnblower.com/
