typically used on rotary compressors

The oil sight glass for air compressor tends to be made of stainless steel or aluminum alloy that screws into the base of the pump or on the compressor sump tank

as some traces of oil and vapors may pass through the air filter material and remain in your air supply

The air compressor inlet valve regulates the capacity of your rotary screw compressor

resulting in more efficiency at higher PSI  ranges up to 232 PSI if

20HP to 40HP Minimum Pressure Check Valve Minimum Pressure Valve typically used on rotary compressorsUsually installed on the discharge port of the separator tank, minimum pressure valves are available in a threaded or flanged version. They include a poppet to maintain minimum pressure in the separator tank when the compressor is started and a check valve to prevent air backflow from the line.
