Top Mount – Arrangement 4V
The AirPro arrangement 4V centrifugal top mount fan allows the fan inlet flange to be mounted directly to the outlet flange on top of a dust collector, cyclone, bin vent, etc. The fan wheel is mounted directly on the motor shaft but, unlike other arrangements, the shaft and motor are in a vertical position.
The 4V arrangement saves space and money often spent on extra ducting. Additionally, as a result of the direct connection and lack of additional ducting, less static pressure is present in the system thereby increasing efficiency. Typical accessories are outlet dampers, silencers, weather guards, & bird screens.
