Analyze the reasons for the stall of the axial fans

When using an axial fan , stall may occur, so what is the reason for the stall of the axial fan?

1. The air volume on both sides of the axial flow fan is unbalanced. The fan stall usually occurs during the parallel operation of the fans, and the lower side of the fan is prone to stall during the low-load operation and the parallel operation of the fans.

2. The working conditions of low fan output, small fan output and high wind pressure are easy to cause the fan to stall;

3. Under the condition of small air volume and high air pressure, the changing characteristics of the air duct can easily cause the fan to stall.

Hope to clarify these reasons, so that it is more conducive to use and operation.
