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 Sull-
air rotary screw air compressor. Compared to other
compressors, the Sullair is unique in mechanical
reliability, 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
guidelines and procedure, operator(s) will be able
to keep the compressor in top operational condi-
tion.

2.2 DESCRIPTION OF COMPONENTS

Refer to Figur e 2 --- 1 . The c omponents of the S ul l a ir
2---stage electric compressor include compressor
unit, electric motor, cooling and lubrication sys-
tem, air inlet system, compressor discharge
Figure 2 ---1 Sullair LS20T Rotary Screw Air Compressor
system, capacity control system and instrument
panel.
The 2---stage Sullair compressor unit is driven by
an industrial motor designed to provide enough
horsepower for more than adequate reserve at
rated conditions.
On air---cooled models, a separate motor driven
fan forces air through the cooler, thereby removing
the compression heat 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.
2.3 SULLAIR COMPRESSOR UNIT, FUNCTIONAL
DESCRIPTION
The compressor unit supplied with your compres-
sor is a 2---stage, positive displacement, flood lubri-
cated---type rotary screw air compressor.
As the rotors turn, air is drawn into the compressor
unit at the first stage inlet. At the outlet of the first
stage the air is compressed and discharged into
