Description
GENERAL
The Powerex Oilless Rotary Scroll Air Compressor has
advanced scroll compressor technology through the
development of a completely oilless unit. The Powerex Scroll
Compressor offers a dynamically balanced air end which
insures vibration-free operation. The rotary design permits a
continuous 100% duty cycle. No oil separation, oil fi ltration,
or inlet valves are required on the Powerex Scroll unit.
COMPRESSION CYCLE
The Powerex oilless rotary scroll air compressor is based on
the theory of scroll compression. A scroll is a free standing,
intricate spiral bounded on one side by a solid, fl at plane or
base. A scroll set, the basic compression element of a scroll
compressor, is made up of two identical spirals which form
right and left hand parts. One of these scroll components
is indexed or phased 180° with respect to the other so the
scrolls can mesh. Crescent-shaped gas pockets are formed
and bounded by the spirals and the base plate of both
scrolls. As the moving scroll is orbited around the fi xed scroll,
the pockets formed by the meshed scrolls follow the spiral
toward the center and diminish in size. The moving scroll is
prevented from rotating during this process so the 180° phase
relationship of the scrolls is maintained. The compressor’s
inlet is at the outer boundary of the scrolls. The compressed
gas is discharged through the outlet at the center of the fi xed
scroll so no valves are needed.
TIP SEAL
The tip seal on the scroll compressor is self-lubricated
and allows the unit to operate effi ciently without oil and
expensive fi ltration. On standard pressure units, the tip seal
should be replaced every 10,000 hours of operation. On high
pressure units, the tip seal should be replaced every 5,000
hours of operation.
BEARINGS
The bearings on the scroll compressor are regreaseable to
allow extended compressor life. For standard pressure units,
service should be performed every 10,000 hours of operation.
For high pressure units, service should be performed every
5,000 hours of operation.
DRY TYPE INLET FILTER (P/N ST073925AV)
Order element P/N ST073921AV for both the 3 HP and 5HP
units. Change every 2,500 hours or more often in dirty
locations.

HOURMETER
The hourmeter on the scroll compressor indicates the
actual number of hours the unit has been in operation. The
hourmeter is also used to determine maintenance and service
timing. An hourmeter must be installed with every
Scroll compressor.
CONDENSATE DRAIN VALVE
A condensate drain valve must be installed on every tank
to allow removal of the liquid which will collect during
compressor operation.
Drain liquid from tank daily.

Breathable Air Warning
This compressor/pump is not equipped and should
not be used “as is” to supply breathing quality air.
For any application of air for human consumption,
you must fi t the air compressor/pump with suitable
in-line safety and alarm equipment. This additional
equipment is necessary to properly fi lter and purify
the air to meet minimal specifi cations for Grade D
breathing as described in Compressed Gas Association
Commodity Specifi cation G 7.1 - 1966, OSHA 29 CFR
1910. 134, and/or Canadian Standards Associations
(CSA).
DISCLAIMER OF WARRANTIES
IN THE EVENT THE COMPRESSOR IS USED FOR THE
PURPOSE OF BREATHING AIR APPLICATION AND
PROPER IN-LINE SAFETY AND ALARM EQUIPMENT
IS NOT SIMULTANEOUSLY USED, EXISTING
WARRANTIES SHALL BE VOIDED, AND POWEREX
DISCLAIMS ANY LIABILITY WHATSOEVER FOR ANY
LOSS, PERSONAL INJURY OR DAMAGE.
4. Clearance must allow for safe, effective inspection and
maintenance.
5. If necessary, use metal shims or leveling pads to level the
compressor tank or basemount unit. Never use wood to
shim the unit.
VENTILATION
1. If the scroll compressor is located in a totally enclosed
room, an exhaust fan with access to outside air must be
installed.
2. Never restrict the cooling fan exhaust air.
3. Never locate the compressor where hot exhaust air from
other heat generating units may be pulled into the unit.
WIRING
Refer to the general product manual. All electrical hook-ups
must be performed by a qualifi ed electrician. Installations
must be in accordance with local and national electrical
codes.
Use solderless terminals to connect the electric power source.

Installation (Continued)
PIPING
General Guidelines
Refer to the general product manual.
1. Make sure the piping is lined up without being
strained or twisted when assembling the piping for the
compressor.
2. Appropriate expansion loops or bends should be installed
at the compressor to avoid stresses caused by changes in
hot and cold conditions.
3. Piping supports should be anchored separately from the
compressor to reduce noise and vibration.
4. Never use any piping smaller than the compressor outlet
connection.
5. Use fl exible hose to connect the outlet of the compressor
to the piping so that the vibration of the compressor
does not transfer to the piping.
Remote Intake Piping
Powerex Compressor Systems with pipe thread connectors on
the intake fi lters are intended for installation with remote air
intake. Piping for the remote intake system must be installed
at the fi nal operating site.
Under some conditions, the intake piping may facilitate the
condensation of humidity in the intake air stream into liquid
water.
The intake fi lters supplied by Powerex will
not stop ingestion of liquid water by the
pumps. Liquid water going into the pumps will damage the
pumps and void the warranty.
Always install drip legs with suffi cient capacity to capture
liquid water in the intake piping before the air fi lters. Drip
legs must be sized with low enough air velocity to make sure
they are effective at capturing liquid water in the intake air
and must be maintained (drained) at frequent intervals to
make sure they remain effective.
Operation
BEFORE START UP
1. Make sure all safety warnings, labels and instructions have
been read and understood before continuing.
2. Remove any shipping materials, brackets, etc.
3. Confi rm that the electric power source and ground have
been fi rmly connected.
4. Be sure all pressure connections are tight.
5. Check to be certain all safety relief valves, etc., are
correctly installed.
6. Check that all fuses, circuit breakers, etc., are the proper
size.
7. Make sure the inlet fi lter is properly installed.
8. Confi rm that the drain valve is closed.
START-UP AND OPERATION
1. Follow all the procedures under “Before start-up” before
attempting operation of the compressor.
2. Switch the electric source breaker on.
3. Open the tank discharge valve completely.
4. Check that the compressor operates without excessive
vibration, unusual noises or leaks.
5. Close the discharge valve completely.
6. If the pressure does not rise on a three phase unit, turn
the unit off. Have a qualifi ed electrician switch the
breaker OFF and exchange the L1 and L2 connections (two
out of three phases of electric source) inside the magnetic
starter enclosure.
7. Check the discharge pressure. Also make sure the air
pressure rises to the designated pressure setting by
checking the discharge pressure gauge.
8. Check the operation of the pressure switch by opening the
tank outlet valve and confi rming the compressor starts as
pressure drops.
SAFETY VALVES
Tank mounted compressors are shipped from the factory with
safety valves installed in the tank. The fl ow capacity of the
safety valve is equal to or greater than the capacity of the
compressor.
1. The pressure setting of the safety valve must be no higher
than the maximum working pressure of the tank.
2. Safety valves should be placed ahead of any possible
blockage point in the system, i.e. shutoff valve.
3. Avoid connecting the safety valve with any tubing or
piping.
4. Manually operate the safety valve every six months to
avoid sticking or freezing.
