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 5 (Maintenance) to see how surpris-
ingly easy it is to keep your air compressor in top op-
erating condition.

2.2 DESCRIPTION OF COMPONENTS

Refer to Figures 2-1
assemblies of the air compressor are clearly shown.
The complete package includes compressor, elec-
tric motor, starter, compressor inlet system, com-
pressor discharge system, compressor lubrication
and cooling system, capacity control system, instru-
ment 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 aftercooler
and fluid cooler thereby removing the compression

and 2-2. The components and
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 compression
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 acces-
sible 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 con-
tinuous pulse-free compression to meet your needs.
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
warranty.
Sullair 24KT compressors are filled with a fluid
which rarely needs to be changed. In the event a
change of fluid is required, use only Sullair 24KT
fluid. MIXING OF OTHER LUBRICANTS WITHIN
THE COMPRESSOR UNIT WILL VOID ALL WAR-
RANTIES!
