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 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
operating condition.

2.2 DESCRIPTION OF COMPONENTS

Refer to Figur es 2 --- 1
and assemblies of the air compressor are clearly
shown. The complete package includes compres-
sor, electric motor, starter, compressor inlet
system, compressor discharge system, com-
pressor lubrication and cooling system, capac-
ity control system, instrument panel, aftercooler

and a combination separator and trap, all
mounted on a heavy gauge steel frame.
On air---cooled models, a fan draws air over the mo-
tor 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 ex-
changer 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 filter and
control valves. The inlet air filter is also easily acces-
sible for servicing.
