This 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. The design is based on BS 848 and ISO 1042. Extra blades are provided for comparison study.
- Inlet and discharge pressures vs blower speed.
- Flow rate vs speed.
- Blower input, output and efficiency.
- Comparison of backward, radial, and forward blade impellers.
