2.1 INTRODUCTION
Your new Sullair lubricated rotary screw air com-
pressor will provide you with a unique experience in
improved reliability and greatly reduced mainte-
nance.
Compared to other types of compressors, the
Sullair rotary screw is unique in mechanical reliabil-
ity, with "no wear" and "no inspection" required of
the working parts within the compressor unit.
Read Section 7 (Maintenance) to see how surpris-
ingly easy it is to keep your air compressor in top
operating condition. Should any questions arise
which cannot be answered in the following text, call
your nearest Sullair representative or the Sullair
Corporation Service Department (see back cover).
2.2 DESCRIPTION OF COMPONENTS
cooled). The components and assemblies of the air
compressors are clearly shown. The complete
package includes compressor, electric motor, com-
pressor inlet system, compressor discharge sys-
tem, compressor cooling and lubrication system,
capacity control system, and Supervisor control
system, all mounted on a heavy gauge steel frame.
On air-cooled models, a separate motor-driven fan
forces air through the cooler/aftercooler assembly,
thereby removing the heat of compression from the
cooling fluid.
On water-cooled models, fluid is piped into a four-
pass exchanger where the heat of compression is
removed from the fluid. A fan is used to supply suf-
ficient ventilating air to the compressors equipped
with a canopy.
Both air-cooled and water-cooled versions have
easily accessible items such as the fluid filters and
control valves. The inlet air filters are also mounted
for easy access and servicing.
2.3 SULLAIR COMPRESSOR UNIT, FUNCTIONAL
DESCRIPTION
Sullair air compressors feature the Sullair compres-
sor unit, a single-stage, positive displacement,
lubricated-type compressor. This unit provides con-
tinuous pulse-free air compression to meet your
needs. With a Sullair compressor, there is no main-
tenance or inspection of the internal parts of the
compressor unit permitted in accordance with the
terms of the warranty.
Sullair 24KT compressors are filled with a fluid
which rarely needs to be changed. In the event a
change or make-up fluid is required, use only
Sullair 24KT fluid.
Sullair recommends that a 24KT sample be taken
at the first filter change and sent to the factory for
analysis. This is a free service. The sample kit with
instruction and self-addressed container is to be
supplied by your Sullair representative at start-up.
The user will receive an analysis report with recom-
mendations.
Fluid is injected into the compressor unit in large
quantities and mixes directly with the air as the
rotors turn, compressing the air. The fluid flow has
three primary functions:
•
As coolant, it controls the rise of air temper-
ature normally associated with the heat of
compression.
•
Seals 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
compressor unit, the fluid is separated from the air.
At this time, the air flows to the service line and the
fluid is cooled in preparation for re-injection.
The fluid also serves as lubricant for the anti-friction
bearings and the drive gear sets.
2.4 COMPRESSOR COOLING AND LUBRICATION
SYSTEM, FUNCTIONAL DESCRIPTION
. The
cooling and
lubrication system
(air-cooled version) consists of
a
fan
,
radiator-type cooler/aftercooler assem-
bly
,
full-flow main line filter
,
thermal valve
and
interconnecting piping.
For the water-cooled models, a shell and tube fluid
cooler, and aftercooler are substituted for the radia-
tor-type cooler on air-cooled compressors.
The pressure in the receiver/sump causes fluid flow
DO NOT mix different types of fluids.
MIXING OF OTHER LUBRICANTS WITHIN THE
COMPRESSOR UNIT WILL VOID ALL WAR-
RANTIES.
Standard thermal valve temperature is 175ºF/79ºC
(operating temperature of 180ºF/ 82ºC). Thermal
valve temperature is 190ºF/88ºC (operating tem-
perature of 195ºF/ 91ºC) for HH, XH and 24KT
machines.
