Description of Axial Flow Fan Demonstration Unit

Axial Flow Fan Demonstration Unit is a bench top unit for a study of axial flow fan characteristics with data analysis by computer. The unit consists of a small axial flow fan with DC motor on a steel base, a speed control switch, inlet and outlet ducts, an interface box, sensors, and software. The box includes power supply for the fan and computer interface unit. It also provides interface ports to sensors and computer. The unit is to be use with a computer.

Experiments of Axial Flow Fan Demonstration Unit

1. Flow rate VS pressure
2. Fan input, output and overall efficiency.
3. Effect of speed on fan performance.
