Components

Pressure switch - Auto/Off Switch - In the "auto" position, the compressor shuts off automatically when tank pressure reaches the maximum preset pressure. In the "off" position, the compressor will not operate. This switch should be in the "off" position when connecting or disconnecting the power cord from the electrical outlet or when changing air tools.

Regulator - The regulator controls the amount of air pressure released at the hose outlet.

ASME Safety Valve - This valve automatically releases air if the tank pressure exceeds the preset maximum.
