2.1 INTRODUCTION
Your new Sullair flood--lubricated rotary screw air
compressor will provide you with a unique experi-
ence in improved reliability and greatly reduced
maintenance.
Compared to other types of compressors, the Sull-
air rotary screw is unique in mechanical reliability,
with “no wear” and “no inspection” required of the
working parts within the compressor unit.

system, instrument panel, aftercooler,acom-
bination separator and trap, all mounted on a
heavy gauge steel frame.
On air--cooled models, a fan draws airover the mo-
torandforces it out through the combined aftercool-
er and fluid cooler thereby removing the compres-
sion heat from the compressed air and the cooling
fluid.
On water--cooled models, a shell and tube heat ex-
changerismounted on the compressor frame. Fluid

heat is removed from the fluid. Another similar heat
exchanger cools the compressed air.
Both air--cooled and water--cooled versions have
easily accessible items such as the fluid filters and
controlvalves. Theinlet airfilter isalsoeasilyacces-
sible for servicing.
