4.1 INTRODUCTION
Your Sullair DR---13, rotary screw air compressor
will provide you with improved reliability and re-
duced maintenance.
Read Section 7 (Maintenance) to keep your com-
pressor in top operating condition. Should any
questions arise which cannot be answered in the
following text, call your nearest Sullair office or the
Sullair Corporation Service Department.
IMPORTANT --- Your DR---13 compressor package
utilizes a simple to operate yet sophisticated com-
puterized controller identified throughout this doc-
ument as the Supervisor
II
. All pertinent use of this
device is covered herein. Carefully familiarize your-
self with it before attempting to operate the machin-
ery.
4.2 DESCRIPTION OF COMPONENTS
Refer to Figure
. The standard package in-
cludes a
two--stage compressor and gear box
assembly
, an
electric motor and driveline sys-
tem
, a
Supervisor
II
control assembly
, an
inlet
air system, low pressure (LP)
and
high pressure
(HP) silencing/discharge air systems, air cool-
ing system
, a
load/unload control system
, an
oil
lubrication and cooling system
, and a
sound at-
tenuating enclosure
, all mounted on a fabricated
steel frame.
Air---cooled heat exchangers are used on all mod-
els. A motor driven fan is used to ventilate the interi-
or of the sound attenuating enclosure. The Super-
visor
II
assembly is easily accessible for servicing
behind a hinged and locked separate enclosure
panel door.
4.3 COMPRESSOR UNIT, FUNCTIONAL DESCRIP-
TION
Sullair DR---13 compressors feature a two---stage,
oil free, rotary screw design. The rotor profiles and
stators, which are protected with anti---corrosion
coatings, deliver near pulse---free compressed air
to meet your demands. The rotor shafts are
mounted on anti---friction bearings and are sealed
by floating carbon ring/stainless steel cage assem-
blies. Both stages are driven by a common bull
gear and speed optimized individual pinions, and
are precisely mounted to the rigid gear box. Timing
gears synchronize each male/female rotor pair for
contact---free operation. Variations of compressor
speed, and ultimately flow capacity, are deter-
mined by the ratio of pinions--- to---bull gear set
