6. SYSTEM OF EACH COMPONENT
6.1 Compressed Air/Lubricant System
6.1.1 Compressed air flow
The air under atmospheric pressure is taken in
the unit through Air Intake Filter and is com-
pressed by a compressor to the specified pressure.
This Compressed Air flows in the Oil Case to-
gether with Lubricant, and by which Compressed
Air and Lubricant are separated. Segregated
Compressed Air is cooled in the Aftercooler and
then discharged out.
6.1.2 Lubricant flow
The Lubricant circulates in the unit by means of
pressure difference between the pressure in the
Oil Case and the one in the suction side of the
Compressor. The mixture of Compressed Air and
Heat Exchanged Lubricant are separated in the
Oil Separator into the Compressed Air and the
Lubricant. Segregated Lubricant is cooled in the
Oil Cooler afterwards and returns to the suction
side of Compressor, then it makes Heat Exchange
with another Compressed Air again.
