The non-return valve is a one-way valve that allows air to enter the tank from the
compressor pump, but prevents the reverse of this flow.
The drive guard covers the V-belt(s), engine or motor pulley, and the compressor pump
pulley. It is a critical safety device.
A drain valve is fitted to the bottom of the air receiver tank to permit the release of water
condensate that would otherwise corrode the tank and damage pneumatic devices.
The pressure within the air receiver tank is indicated on the pressure gauge.
