This is a bench top unit for studying the small centrifugal fan characteristics.
The unit consists of a small industrial centrifugal fan with a backward blade impeller and a motor on a steel base, an advanced inverter, inlet and outlet ducts, and measuring instruments. An interchangeable forward blade impeller is provided for comparison of operating characteristics.
- Flow rate vs pressure.
- Fan input, output and overall efficiency.
- Effect of speed on fan performance.
- Comparison of backward and forward blade impellers.
