Axial Flow Fan and Centrifugal Fan are significantly different in many aspects. The following is a detailed comparison:

1. Exhaust direction

Axial Flow Fan: The direction of exhaust air is straight along the direction of the shaft, and the air intake and exhaust of the fan are on a parallel line of the shaft.

The exhaust direction of the Centrifugal Fan is perpendicular to the direction of the intake vent, which can realize the exhaust in the specified direction of 360 degrees.

2. Installation method

Axial Flow Fan: The installation method is relatively convenient, such as the duct fan can be installed directly in the pipeline or on the wall, and the fixed fan is fixed through the base.

The installation method is mainly made of steel structure bracket, which should be maintained in a straight and solid state during installation, the part embedded in the wall should be deep into two-thirds of the wall, and the washer should be added when bolted to prevent loosening.

3. Air volume and pressure

Axial Flow Fan: The air volume is large, but the wind pressure is small. The working principle is that the gas moves in the axial direction through the rotation of the impeller, so the wind pressure is small, but the air volume is large.

Centrifugal Fan: Wind volume and wind pressure are relatively large. It rotates through the impeller to form centrifugal force for gas transmission, generally requires closed installation, so it can produce higher wind pressure, but relatively speaking, the air volume is not as large as the axial flow fan.

In summary, there are obvious differences between the two in terms of exhaust direction, installation mode, air volume and pressure, shape structure, maintenance mode and application field. When choosing to use, it should be comprehensively considered according to specific needs and occasions.
