A labeled photo diagram of an air compressor, with arrows pointing to the hose connectors, pressure adjustment knob, pressure gauges, pump, motor, air tank, and drain valve.

The pressure switch may also incorporate an unloader valve that reduces tank pressure when the compressor is turned off. Many articulated-piston compressors are oil lubricated.

The Clarke SHHH50/350 Shhh Air Max is a high output air compressor for when performance really matters.
