dump valve installed in the bottom of the separator chamber. The moisture separator is enclosed in an electric heater
that prevents ice from forming in the separator as compressed air expands. A relief valve is installed on the moisture
separator. It will protect the unit if the pressure switch fails. This relief valve will open at 3950 psig (Max.) and provide
rated-flow relief.
2. A pressure switch which is installed at the outlet port will stop the motor and compressor when the
system pressure reaches 3200 100 psig and restart the motor when the pressure drops to 2800 psig (min.).
3.
A check valve, installed upstream of back pressure valve, prevents reverse air flow to the moisture
separator.
4.
Pressure relief valves installed in the high-pressure pneumatic line open automatically to
