With the continuous expansion of the application scope of centrifugal fan and axial flow fan, many new customers will ask the technicians of Hidili fan what is the difference between the two fans. Let's briefly introduce the difference between them.
1. The centrifugal fan changes the flow direction of the medium in the air duct, while the axial fan does not change the flow direction of the medium in the air duct;
2. The former has high air volume and pressure, while the latter has low air volume and pressure;
3. The former is more complex and the latter is simpler;
4. The motor of the former is generally connected with the fan through the shaft, and the motor of the latter is generally in the fan;
5. The former is often installed at the inlet and outlet of the air conditioning unit, boiler drum, induced draft fan, etc., while the latter is often installed in the middle of the air duct or at the front end of the air duct outlet.
The air flow direction of axial flow fan is perpendicular to the rotation direction of blade, and the air flow direction of centrifugal fan is tangent to the rotation direction of blade. What form of fan to choose is mainly to consider the flow and system resistance loss. I hope this knowledge can be helpful to you.
