The oil injected into the air end has the following function:
– It dissipates the compression heat (cooling)
– It seals the gaps between the screws and between the screws and housing
– It lubricates the bearings

1 = Compressed air/oil receiver
The oil separated from the compressed air through the force of gravity collects
in the compressed air/oil receiver.
The system pressure forces it out of the receiver into the air end.
2 = Thermostatic oil control valve
Depending on the oil temperature, the thermostatic oil control valve either
allows the oil to pass through the oil cooler or through a bypass (e.g. in the
starting phase).
Thus the oil constantly maintains its optimum operating temperature.
3* = Oil cooler (air or water cooled, on site) to be provided by customer.
The oil cooler cools down the hot oil to operating temperature.
4 = Oil filter
The oil filter traps impurities in the oil.
5 = Air end
The injected oil returns to the compressed air/oil receiver together with the
compressed air. There, it is separated through the force of gravity.
6 = Drainage line
The air end suctions the residual oil which collects in the oil separator back
into the oil circuit via a drainage line.
