2.1 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 Sul-
lair 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. Should any questions arise
which cannot be answered in the following text, call
your nearest Sullair representative or the Sullair
Corporation Service Department.
2.2 DESCRIPTION OF COMPONENTS
. The c omponents a nd assem -
blies of the air compressor are clearly shown. The
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
structural steel frame.
On air---cooled models, the cooling package is re-
mote---mounted and shipped as a separate unit.
The separate motor---driven fan cooling package
forces air through the coolers, which removes the
heat of compression from the cooling fluid.
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.
