The difference between DC Fan centrifugal and axial flow

"DC Fan" axial flow, the air flow is the fan shaft in the same direction (ie, direction and parallel to the axis of the wind), such as electric fans, air conditioning unit is an axial flow fan mode. Centrifugal fans and axial fans The main difference is:
1, centrifugal fans change the flow of the medium within the duct, but does not change the flow of axial fan duct within the medium;
2, the former installation is more complex;
3, the former motor and fan is typically connected by a shaft, which is generally in the fan motor;
4, the former often installed in the air conditioning unit inlet and outlet of the boiler drum, induced draft fan, and so on. The latter were often installed in the duct or duct outlet tip.
There are also mixed flow (mixed) fans, high pressure coefficient than the axial fan, flow coefficient than the centrifugal fan. Fill the gaps in the axial fans and centrifugal fans between. Along with easy installation features.
