Centrifugal Blower Test Rig

quick overview :

Centrifugal Blower Test Rig

This equipment comprises of a FD Fan Centrifugal Blower coupled to a DC Motor. Three interchangeable impellers with forward, backward and radial vanes are provided with the test rig. Power input to the DC Motor is varied by means of a Thyristor controlled DC Drive to vary the RPM of motor. A RPM Indicator with Proximity sensor indicates the RPM of Blower.

A Pitot Tube is provided in the delivery line of blower for static and dynamic pressure measurement
