2.1 INTRODUCTION
Your new Sullair flood-lubricated rotary screw air
compressor will provide you with a unique experi-
ence in improved reliability and greatly reduced
maintenance.
Compared to other types of compressors, the
Sullair rotary screw is unique in mechanical reliabil-
ity, with "no wear" and "no inspection" required of
the working parts within the compressor unit.
Read Section 7 (Maintenance) to see how surpris-
ingly easy it is to keep your air compressor in top
operating condition.
2.2 DESCRIPTION OF COMPONENTS
Refer to Figures 2-1 and 2-2. The components and
assemblies of the air compressor are clearly shown.
The complete package includes compressor,
electric motor, starter, compressor inlet system,
compressor discharge system, compressor
lubrication and cooling system, capacity control
system, instrument panel, aftercooler, a combi-
nation separator and trap, all mounted on a heavy
gauge steel frame.
On air-cooled models, a fan draws air over the
motor and forces it out through the combined after-
cooler and fluid cooler thereby removing the com-
pression heat from the compressed air and the
cooling fluid.
On water-cooled models, a shell and tube heat
exchanger is mounted on the compressor frame.
Fluid is piped into the heat exchanger where com-
pression heat is removed from the fluid. Another
similar heat exchanger cools the compressed air.
Both air-cooled and water-cooled versions have
easily accessible items such as the fluid filters and
control valves. The inlet air filter is also easily
accessible for servicing.
2.3 SULLAIR COMPRESSOR UNIT, FUNCTIONAL
DESCRIPTION
Sullair air compressors feature the Sullair com-
pressor unit, a single-stage, positive displace-
ment, flood lubricated-type compressor. This
unit provides continuous compression to meet your
needs.
With a Sullair compressor, there is no mainte-
nance or inspection of the internal parts of the
compressor unit permitted in accordance with the
terms of the warranty.
