Description
Air drawn through filter (AF) and open inlet valve (IV) into Airend (E) is compressed. A mix of compressed air
and fluid flows into the reservoir (AR) via check valve (CV). The air is discharged through outlet (AV) via
minimum pressure valve (Vp) and air cooler (Ca).
During loaded operation, minimum pressure valve (Vp) keeps the pressure in the separator tank (AR)
above a minimum value, required for lubrication. An integrated check valve prevents the compressed air
downstream the valve from being vented to atmosphere during unloaded operation. When the compressor
is stopped, check valve (CV) and inlet valve (IV) close, preventing compressed air (and oil) to be vented
into the air filter.
