Unloader Valves & Idle Down Pistons

Unloader valves are used to release pressure from air receivers where there is no mechanism to automatically stop the compressor (For example, on petrol or diesel air compressors). Made in USA.

The Unloader Idle Piston is a device that, once the unloader valve is activated, brings the revs of the engine down to idle, so both compressor and engine are working at a much reduced speed. Made in the USA.
