Description of Centrifugal Blower Test Set

Centrifugal Blower Test Set a bench top unit for studying the centrifugal blower characteristics. The unit consists of an industrial type centrifugal blower with a motor and an inverter, inlet and outlet ducts with flow straighteners, a damper, and measuring instruments. Extra blades are provided for comparison study.

Experiments of Centrifugal Blower Test Set

1. Inlet and discharge pressures vs blower speed.
2. Flow rate vs speed.
3. Blower input, output and efficiency.
4. Comparison of backward, radial, and forward blade impellers.
