The difference between centrifugal fans and axial fans lies in:  

1. The centrifugal fan changes the flow direction of the medium in the air duct, while the axial flow fan does not change the flow direction of the medium in the air duct;  

2, the former air volume and wind pressure are very large, the latter air volume and wind pressure are very low;  

3, the former installation is more complex, the latter installation is simple;  

4, the former motor and fan are generally connected through the shaft, the latter motor is generally in the fan;  

5, the former is often installed in the air conditioning unit inlet and outlet, boiler drum, induced draft fan, etc., the latter is often installed in the air duct, or the front end of the air duct outlet
