5.1 INTRODUCTION
Your new Sullair lubricated rotary screw air com-
pressor will provide you with a unique experience in
improved reliability and greatly reduced mainte-
nance.
Compared to other types of compressors, the Sull-
air rotary screw is unique in mechanical reliability,
with "no wear" and "no inspection" required of the
working parts within the compressor unit.
Read Section 6 (Maintenance) to see how surpris-
ingly easy it is to keep your air compressor in top op-
erating condition. Should any questions arise which
cannot be answered in the following text, call your
nearest Sullair representative or the Sullair Corpo-
ration Service Department.

COMPRESSOR SYSTEMS
complete package includes compressor, electric
motor, compressor inlet system, compressor
discharge system, compressor cooling and lu-
brication system, capacity control system, and
Supervisor II control system, all mounted on a
heavy gauge steel frame.
On air--cooled models, a separate motor--driven fan
forces air through the cooler/aftercooler assembly,
thereby removing the heat of compression from the
cooling fluid.
On water--cooled models, fluid is piped into a four--
pass exchanger where the heat of compression is
removed from the fluid. A fan is used to supply suffi-
cient ventilating air to compressors equipped with a
canopy.
Both air--cooled and water--cooled versions have
easily accessible items such as the fluid filters and
control valves. The inlet air filters are also mounted
for easy access and servicing.
