From the "AC Fan" installation can be reflected in the difference between different fan before the centrifugal fan relatively complicated to install them, and axial flow fan comparison is relatively simple, and the installation time is relatively short. Centrifugal fan in the installation, pay attention to the motor and bearings of the link, in general centrifugal fan motors are connected together by a bearing, but the axial fan motor is mounted directly inside the fan, the user does not need too much interference, which is why axial fan installation is relatively simple reason.
