The rotary vane compressor in the unit is powered by an electric motor. A pressure gauge is used to read the discharge pressure, while an orifice meter and a manometer help measure the air intake. An energy meter is used to calculate the power input to the compressor. This allows students to determine the volumetric efficiency, power consumption, and free air delivery of the compressor.

Experimental Objective

To become familiar with the concept of air pressure.

To determine the volume of air compressed and delivered.
