The plenum fans in VEX4000 units consist of energy-optimised and directly driven centrifugal fans without fan housing and with backward curved blades.
Fan
The fan consists of a fan impeller mounted directly on the shaft journal. The fan impeller is made of 100% recyclable material.
Fan suspension
The motor and fan are mounted in a fan suspension with oscillation dampers which can be pulled out on rail sections in the base of the unit for servicing and cleaning.
Motor
The motor is a flange motor connected via a terminal box, and EC motors of class IE5 for optimum overall efficiency.
Vibration-free
On the suction side, the inlet funnel has been fitted against the suction chamber. Metal contact is avoided by means of a flexible rubber gasket, which ensures that the fan works without transferring vibrations to the rest of the unit.
