5.1 INTRODUCTION

Your new Sullair ES---8 Integral Compressor/Dryer
will provide you with improved reliability and greatly
reduced maintenance.
Compared with other types of compressor units,
the Sullair rotary screw is unique in mechanical reli-
ability, with "no wear" and "no inspection" required
of the working parts within the compressor unit.
Read Section 9 (Maintenance and Troubleshoot-
ing) to keep your ES---8 Integral Dryer in top operat-
ing condition. Should any questions arise which
cannot be answered in the following text, call your
nearest Sullair office or the Sullair Corporation Ser-
vice Department.
5.2 COMPRESSOR SYSTEM DESCRIPTION OF
COMPONENTS
Refer t o Figure 5 --- 1. The components a nd assem -
blies of the ES---8 Series air compressor are clearly
shown. The complete compressor consists of an
encapsulated compressor system, inlet sys-
tem, cooling system, control system and Super-
visor II control system.
5.3 COMPRESSOR SYSTEM, FUNCTIONAL DE-
SCRIPTION
Refer t o Figure 5 --- 2. The encapsula ted compres -
sor includes compressor unit, fluid management
system, and drive motor. The Sullair compressor

unit is a single---stage positive displacement lubri-
cated---type compressor. This unit is equipped with
tapered roller bearings on the discharge, and cylin-
drical roller bearings on the inlet end for high load
carrying capacity. This unit provides continuous
pulse---free air compression to meet your needs.
With a Sullair compressor there will be no mainte-
nance or internal inspection of the compressor.
WARNING
!
DO NOT remove caps, plugs and/or other compo-
nents when compressor is running or pressur-
ized.
Stop compressor and relieve all internal pres-
sure before doing so.
Fluid is injected into the compressor unit in large
quantities and mixes directly with the air as the ro-
tors turn, compressing the air. The fluid flow has
three main functions:
1. As coolant, it controls the rise of air temperature
normally associated with the heat of compres-
sion.
2. It seals the leakage paths between the rotors
and the stator and also between the rotors
themselves.
3. It acts as a lubricating film between the rotors al-
lowing one rotor to directly drive the other, which
is an idler.
