The difference between centrifugal fan and axial flow fan

What is the difference between centrifugal fan and axial flow fan? To know the difference between centrifugal fan and axial flow fan, it is first necessary to know the working principle of mixed flow fan and axial flow fan. Ventilation principle of centrifugal fan: the gas does both centrifugal movement and axial movement. The ventilation principle of the axial flow fan: the gas flows parallel to the direction of the fan axis.

1. What is the difference in appearance? Axial flow fan needs gas according to the axial movement, usually in a cylindrical shape. And centrifugal fan because of the characteristics of more elbow, usually the shape of a volute.

2. What is the difference in the exhaust direction? The exhaust direction of the axial flow fan is discharged parallel along the direction of the main axis, and the air inlet and exhaust outlet of the fan are on the parallel line of the main axis. The exhaust direction of the centrifugal fan is perpendicular to the air inlet direction, and the specified exhaust direction of 360 can also be realized.

3.The exhaust flow pressure has and is different? The air volume and pressure of axial flow fan is small, while the air volume of centrifugal fan is relatively large.

4. What is the difference in the installation method? Common axial flow fan structure is simple, the installation is also relatively simple, is generally directly installed. And the centrifugal fan because of more elbow, the air supply distance is far, the pipeline resistance is large, the installation is more complex.

5. What is the difference between the impeller motor? The adjustable of axial flow fan makes the axial flow fan impeller divided into 4 and 6 wheels. The installation of simple axial flow motor is generally directly installed in the case interior, the centrifugal fan is more complex because of the structure, generally installed in the outside of the suction tube, connected to the main shaft.

There are also some users are more concerned about the problem, such as the price, environmental protection function, this nature can not be determined, should be based on the actual needs of the scene to determine the appropriate fan.
