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 2-1A, 2-1B and 2-2. The compo-
nents and assemblies of the air compressor are
clearly shown. The complete package includes
compressor, electric motor, starter, compressor
inlet system, compressor discharge system, com-
pressor lubrication and cooling system, capacity
control system, instrument panel, aftercooler, a
combination 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 compres-
sor unit, a single-stage, positive displacement,
flood lubricated-type compressor. This unit provides
continuous compression to meet your needs.
