Air drawn in through filter (AF) and check valve (CV) is compressed in compressor element (E).
A mixture of compressed air and oil flows into the air receiver/oil separator (AR). The air is discharged
through
the outlet valve via minimum pressure valve (Vp), air cooler (Ca) and condensate trap (MT).
Minimum pressure valve (Vp) prevents the receiver pressure from dropping below a minimum
pressure and
includes a check valve which prevents blow-back of compressed air from the net.
Full-Feature compressors are provided with a dryer (DR).
