6.1 Compressed Air and Oil Subsystems
6.1.1 Compressed air subsystem
The air under atmospheric pressure is taken in the unit
through Air Intake Filter and is compressed by a com-
pressor to the specified pressure.
This Compressed Air flows in the Oil Separator Tank
together with Lubricant, and by which Compressed Air
and Lubricant are separated. The compressed air after
the oil separation in the Oil Separator Tank is cooled in
the Aftercooler and then discharged out.
6.1.2 Oil subsystem
The lubricant circulates in the unit by means of pres-
sure dif ference between the pressure in the Oil
Separator Tank and that in the suction side of the com-
pressor. The mixture of the compressed air and the
lubricant which exchanged the heat from the com-
pressed air to the lubricant is separated to the com-
pressed air and the lubricant in the Oil Separator Tank.
The separated lubricant is cooled in the Oil Cooler
afterwards, returns to the suction side of Compressor
and exchange heat from compressed air again.
