Description
Air drawn through filter (AF) and open inlet valve (IV) into compressor element (E) is compressed.
Compressed air and oil flow into the oil tank (OT). The air is discharged through outlet valve (AV) via
minimum pressure valve (Vp) and air cooler (Ca).
During loaded operation, minimum pressure valve (Vp) keeps the pressure in the separator tank (OT) 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, inlet valve (IV) closes, preventing compressed air and oil to be vented into
the air filter.
A condensate trap (MT) downstream the air cooler is included.
On Full-Feature compressors, the air flows through air dryer (DR) before it is discharged through outlet valve
(AV). Also see section Air dryer .
