Where is the unloader valve on an air compressor?
Where Is the Unloader Valve Located? If you own a smaller reciprocating air compressor, you’ll likely find the unloader valve mounted on or inside the pressure switch. When the switch shuts the compressor off, it actuates the valve.
Why does my air dryer keeps purging?
When the air pressure becomes greater than that of the preset “cut-out”, the governor controls the unloader mechanism of the compressor to stop the compressor from building air and also causes the air dryer to purge.
What is unloader valve?
An air compressor unloader valve is a device used by air compressors to release the trapped air inside the compression chamber and tank discharge line when the motor stops. This allows the motor to start up easier. In general there are two types of air compressor unloader valves, electrical and mechanical.

Water leaks and inconsistent behavior are also signs of a potential failure in the near future. González: The typical signal when there is an unloader malfunction is a reduction of flow through the nozzle, which results in pressure loss.
