2.3 SULLAIR COMPRESSOR
UNIT, FUNCTIONAL
DESCRIPTION
Sullair compressors feature the Sullair compressor
unit, a single-stage, positive displacement, flood
lubricated-type compressor. This unit provides
continuous compression to meet your needs.
NOTE
With a Sullair compressor, there is no
maintenance or inspection of the internal
parts of the compressor unit permitted in
accordance with the terms of the war-
ranty.
Sullair compressors are factory-filled with Sullair
AWF lubricant. For more information on fluid fill, refer
to "Application Guide" on page 32.
Fluid is injected into the compressor unit hoses and
mixes directly with the air as the rotors turn,
compressing the air. The fluid flow has three basic
functions:
1. As coolant, it controls the rise of air tempera-
ture normally associated with the heat of
compression.
2. Seals the clearance paths between the
rotors and the stator and also between the
rotors themselves.
3. Acts as a lubricating film between the rotors
allowing one rotor to directly drive the other,
which is an idler.
After the air/fluid mixture is discharged from the
compressor unit, the fluid is separated from the air.
At this time, the air flows through an aftercooler and
separator then to your service line while the fluid is
being cooled in preparation for reinjection.
2.4 AIR INLET SYSTEM,
FUNCTIONAL DESCRIPTION
Refer to Figure 2-2. The compressor inlet system
consists of one air filter, a compressor air inlet valve
16
and interconnecting piping to the compressor. Also,
an air filter restriction indicator gauge is located next
to the air filter housing.
The air filter is a 2-stage unit with a safety element
dry element-type filter. This filter is capable of
cleaning extremely dirty air. However, in such cases,
frequent checks of the air filter will be required.
Referring to the air filter restriction gauge will indicate
when restriction of the air passing through the filter
becomes too high.
At this time, change the air filter element. Refer to
"Air Filter Maintenance" on page 42. This indicator
should be checked daily, after start-up under normal
conditions.
The compressor air inlet valve controls the amount of
air intake of the compressor in response to the air
demand.
