2.3 SULLAIR COMPRESSOR UNIT,
FUNCTIONAL DESCRIPTION
Sullair air compressors feature the Sullair compressor unit,
a single-stage, positive displacement, flood lubricated-
type compressor. This unit provides continuous
compression to meet your needs.
NOTE
With a Sullair compressor, there is no
maintenance or inspection of the
internal parts of the compressor unit
permitted in accordance with the
terms of the warranty.
The 1100e through 1800e Series compressors are
factory-filled with Sullube lubricant. Refer
to SPECIFICATIONS on page 15 for more information
on fluid fill.
Sullair 24KT compressors are filled with a fluid that rarely
needs to be changed. Use only Sullair 24KT fluid in the
event that a fluid change is required.
CAUTION
Mixing of other lubricants within the
compressor unit will void all
warranties.
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 instructions and self-
addressed container is to be supplied by your Sullair
dealer at start-up. The user will receive an analysis report
with recommendations.
Fluid is injected into the compressor unit and mixes directly
with the air as the rotors turn, compressing the air. The fluid
flow has three basic functions:
1. As coolant, it controls the rise of air temperature
normally associated with the heat of compression.
2. Seals the clearance paths between the rotors and the
stator and also between the rotors themselves.
3. 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 through an aftercooler and
separator then to your service line while the fluid is
being cooled in preparation for reinjection.
