2.1 INTRODUCTION

Your new Sullair electric 2-stage, motor-driven air
compressor offers superior performance and reli-
ability requiring a minimal amount of maintenance.
Your compressor is equipped with a 2-stage Sullair
rotary screw air compressor. Compared to other
compressors, the Sullair is unique in mechanical re-
liability, with virtually no wear or loss of perform-
ance. With a Sullair compressor, there is no inspec-
tion required of the working parts within the com-
pressor unit.
As you will see in the following pages, it is very easy
to care for, and/or, to maintain a Sullair compressor.
By careful and step-by-step adherence to the guide-
lines and procedures, operator(s) will be able to
keep the compressor in top operational condition.

2.2 DESCRIPTION OF COMPONENTS

Refer to Figure 2-1 and 2-2. The components of the
Sullair 2-stage electric compressor include com-
Figure 2-1 Sullair 20/12 Rotary Screw Air Compressor (Air-cooled)
pressor unit, electric motor, cooling and lubri-
cation system, air inlet system, compressor dis-
charge system, capacity control system and in-
strument panel.
The 2-stage Sullair compressor unit is driven by an
electric motor designed to provide enough horse-
power for more than adequate reserve at rated con-
ditions.
On air-cooled models, a separate motor-driven fan
forces air through the cooler, thereby removing the
heat of compression from the cooling fluid.
Provisions are made for easy access to such com-
ponents as the fluid filters, control valves and the air
filter. There will be no problem in gaining access to
any components in the event they require service.
