Fan maintenance is a skill what technical personnel must master, and it is necessary to understand the whole structural features of centrifugal fan. 

As for the high capacity centrifugal fan with double supporting, inlet box is necessary.

Inlet end of inlet box is connected to the air duct system; the intermediate shaft of inlet box is placed in the intermediate shaft enclosure;  
the half coupling of motor side is protected by coupling guard; the whole inlet box is fixed on the foundation.In order to reduce the fan noise,inlet box can be equipped with silencer.
