Description
In oil tank (OT) most of the oil is removed from the air/oil mixture by centrifugal action. The rest is removed
by oil separator (OS). The oil collects in the lower part of oil tank (OT).
Air pressure forces the oil from oil tank (OT) through oil cooler (Co) and filter (OF) to compressor element
(E).
The oil system is provided with a thermostatic bypass valve (BV). When the oil temperature is below its set
point, bypass valve (BV) shuts off the supply to oil cooler (Co) and the oil cooler is bypassed.
Thermostatic bypass valve (BV) starts opening the supply from cooler (Co) when the oil temperature has
increased to the set point. At approx. 15 ˚C (27 ˚F) above the set point, all the oil flows through the oil cooler.
