What should be noted when installing a fan?
01/26/2024The installation of fans is generally categorized into two types: shaft horizontal installation and vertical installation, but the installation requirements for each type of fan are different and not every type of installation is supported.
- Fans basically support shaft horizontal installation, as the picture shows:
Axial Fans
Let's look at the centrifugal fans: (when the shaft of the centrifugal fan is installed horizontally, pay attention to the direction of the lead wires)
The lead-out line is facing downward so as to prevent water from directly entering the terminal gap in outdoor applications.
Sometimes it should be noted that the shaft is installed vertically. Fans generally require the stator to face up and the rotor to face down. Some fans have drip holes in the rotor. In the presence of condensation, if the rotor is mounted upward, water will enter into the drip holes and not be able to drain, so the rotor should be mounted downward so that condensation can drain.
As the picture shows:
Axial Fans
For backward centrifugal fans with brackets and mounting plates, make sure the brackets are located on the left and right sides of the fan when installing. If the brackets are located on the top and bottom sides of the fan, as shown in the second picture, the brackets may become deformed due to prolonged operation. Of course, this is not absolute, and some fans can still support any form of mounting.
