Air Compressor Capacity Control Methods

Capacity control determines how a compressor adjusts its output to demand, and the method strongly affects energy use.

Load/Unload Control

The compressor switches between full load and unloaded running, simple and reliable but with some energy loss during unload.

Modulation Control

An inlet valve throttles flow continuously, keeping pressure tight but less efficient at partial load.

Variable Speed Control

Changing motor speed matches output to demand with the highest partial-load efficiency for variable air needs.
