2.1 Introduction

Sullair portable air compressor models offer superior per-
formance and reliability while requiring only minimal
maintenance.
The compressor is equipped with a Sullair rotary screw
compressor unit. Compared to other compressors, the
Sullair is unique in mechanical reliability and compressor
durability. No inspection is required of the working parts
within the compressor unit.
As you continue reading this manual and come to learn
how the compressor operates and is cared for, you will
see how surprisingly easy it is to keep a Sullair compres-
sor in top operating condition.
Read Section 6: Maintenance to keep your compressor
in top operating condition. Should any problem or ques-
tion arise which cannot be answered in this text, contact
your nearest Sullair representative or the Sullair Service
Department.

2.2 Description of components

Refer to Figure 2-1. The components and assemblies of
the Sullair portable air compressor models are clearly
shown. The package includes a compressor, electric
motor, compressor inlet system, compressor cooling and
lubrication system, compressor
capacity control system, instrument panel and electrical
system.
The electric motor is direct coupled to the compressor
unit via a flexible coupling. A separate electric motor-
driven fan forces air through the cooler/aftercooler
assembly, thereby removing the heat of compression
from the cooling fluid.

2.3 Sullair compressor unit,
functional description
Sullair compressors feature the Sullair compressor unit, a
single-stage, positive displacement, flood lubricated-type
compressor. This unit provides continuous compression
to meet your needs.
With a Sullair compressor, there is no mainte-
nance or inspection of the internal parts of the
compressor unit permitted in accordance with
the terms of the warranty.
Sullair compressors are factory-filled with Sullair AWF
lubricant. For more information on fluid fill, refer to Sec-
tion 3.3: Application guide on page 30.
Fluid is injected into the compressor unit hoses and
mixes directly with the air as the rotors turn, compressing
the air. The fluid flow has three basic functions:
• As coolant, it controls the rise of air tempera-
ture normally associated with the heat of com-
pression.
• Seals the clearance paths between the rotors
and the stator and also between the rotors
themselves.
• Acts as a lubricating film between the rotors
allowing one rotor to directly drive the other,
which is an idler.
After the air/fluid mixture is discharged from the compres-
sor unit, the fluid is separated from the air. At this time,
the air flows through an aftercooler and separator then to
your service line while the fluid is being cooled in prepa-
ration for reinjection.
