Cooling System - Chicago Pneumatic CPM 10 Instruction Book

Instruction book
Air pressure in the oil separator tank (OT) forces the oil from the tank to compressor element (E)
via oil cooler (Co) and oil filter (OF). Compressed air and oil flow into oil separator/tank (OT)
where most of the oil is separated from the air by centrifugal action. The remaining oil is removed
by oil separator (OS) and returns to the oil circuit via a separate line. The minimum pressure

circulation under all circumstances.
The oil system is fitted with a by-pass valve (BV). When the oil temperature is below the set-point
of the valve, the by-pass valve shuts off the oil supply from oil cooler. The by-pass valve starts
opening the supply from cooler (Co) when the oil temperature exceeds the setting of the valve.
The setting of the by-pass valve depends on the model. See the section
2.4

Cooling system

The cooling system comprises oil cooler (Co) and fan (FN). The fan, mounted directly onto the
motor shaft, generates the cooling air in order to cool the oil and the internal parts of the
compressor.
