COMPRESSOR OPERATION
➢ The air-oil mixture is sprayed from the screw unit into the separator tank. Thanks to the special
design of the separator tank, the air flow formed inside the tank ensures that the oil particles in the
air-oil mixture become heavier by combining and are diverted onto the inner surface of the tank. In
this way, the oil does not entirely attack onto the separator so that the separator smoothly operates
for long times.
➢ The pulverized oil constrained in the air is held when passing through the filter.
➢ The oil separated air passes through the minimum pressure valve and then the cooling radiator, and
finally dispatched into the airline.
➢ And the oil remaining in the separator tank is cooled down in the cooling radiator, and then re-
dispatched to the oil filter.
The separator tank has three functions:
•
To perform the oil pre-separation process with its special design,
•
To maintain the compressor oil and
•
To protect the separator filter.
