4.1 INTRODUCTION
The Sullair DE-18 Series Rotary Screw Air
Compressor offers superior performance 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 compressor in top condition.
Read Section 7: Maintenance to keep your
compressor in top operating condition. Should any
questions arise which cannot be answered in the
following text, call the Sullair Corporation Service
Department (1-800-SULLAIR ext. 4242).
4.2 DESCRIPTION OF
COMPONENTS
The standard package includes a two-stage
compressor and gear box assembly, a diesel engine,
driveline system, a control assembly, an inlet air
system, low pressure (LP) and high pressure (HP)
silencing/discharge air systems, air cooling system, a
load/unload control system, an oil lubrication and
cooling system, and a sound attenuating enclosure,
all mounted on a fabricated steel frame.
The Sullair compressor unit is driven by an industrial
diesel engine designed to provide enough
horsepower for adequate reserve at rated conditions.
Refer to Engine Operator's Manual for a more
detailed description of the engine.
Air-cooled heat exchangers are used on all models.
An engine-driven fan is used to ventilate the interior
of the sound attenuating enclosure. The controller
assembly is easily accessible for servicing behind a
hinged and locked separate enclosure panel door.
The engine cooling system is comprised of a
radiator, high capacity fan, and thermostats. The
high capacity fan draws air through the radiator,
keeping the engine at the proper operating
temperature.
NOTE
Your DE·18 Series compressor package
utilizes a simple to operate yet sophisti-
cated computerIzed controller. All perti-
nent use of this device Is covered herein.
Carefully familiarize yourself with It
before attempting to operate the machl-
nery.
