Axial Flow Fan Test Set .

Description of Axial Flow Fan Test Set

Axial Flow Fan Test Set is a bench top set for studying industrial type axial flow fan characteristies. The unit consists of a single stage variable pitch axial flow fan and motor, inlet and outlet ducts, and instruments for measurement of air flow rate, pressures, and temperature. The unit is on wheels.

Experiments of Axial Flow Fan Test Set

1. Flow rate vs pressure.
2. Fan input, output and efficiency.
3. Effect of speed on fan performance.
4. Effect of impeller pitch angle on fan performance.
5. Effect of guide vane on fan performance (optional).
