Oil system
Air pressure forces the oil from receivers (AR) through oil coolers (Co), filters (OF) and oil stop valves (Vs)
to compressor elements (E) and the lubrication points.
Oil stop valves (Vs) prevent the compressor elements from flooding with oil when the compressor is stopped.
Valves (BV) by-pass oil coolers (Co) when starting the compressor from a cold condition, so ensuring rapid
warming of the oil to normal working temperature.
In air receivers (AR) most of the oil is removed from the air centrifugally. Almost all of the remaining oil is
removed by the separator elements.
