TIP SEAL
GENERAL
The tip seal on the scroll compressor is
self-lubricated and allows the unit to
operate efficiently without oil and
expensive filtration. The tip seal should
be replaced every 10,000 hours of
operation.
The Powerex Oilless Rotary Scroll Air
Compressor has advanced scroll com-
pressor technology through the devel-
opment 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
filtration, or inlet valves are required
on the Powerex Scroll unit.

DANGER
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 fit
the air compressor/pump with
suitable in-line safety and alarm
equipment. This additional equip-
ment is necessary to properly filter
and purify the air to meet minimal
specifications for Grade D breath-
ing as described in Compressed
Gas Association Commodity
BEARINGS
The bearings on the scroll compressor
are regreaseable to allow extended
compressor life. Service should be per-
formed every 10,000 hours of opera-
tion.
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, flat plane or base. A
scroll set, the basic compression ele-
ment 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
180o 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 fixed scroll, the pockets
formed by the meshed scrolls follow
the spiral toward the center and dimin-
ish in size. The moving scroll is prevent-
ed from rotating during this process so
the 180o phase relationship of the
scrolls is maintained. The compressor’s
inlet is at the outer boundary of the
scrolls. The compressed gas is dis-
charged through the outlet at the cen-
ter of the fixed scroll so no valves are
needed.
DRY TYPE INLET FILTER
(P/N 91348550)
Order P/N 91348550 for both the 3 HP
and 5HP units. Change every 2,500
hours or more often in dirty locations.
Specification G 7.1 - 1966, OSHA 29
CFR 1910. 134, and/or Canadian
Standards Associations (CSA).
HOURMETER
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, EXIST-
ING WARRANTIES ARE VOIDED,
AND POWEREX DISCLAIMS ANY
LIABILITY WHATSOEVER FOR
ANY LOSS, PERSONAL INJURY OR
DAMAGE.
The hourmeter on the scroll compres-
sor indicates the actual number of
hours the unit has been in operation.
The hourmeter is also used to deter-
mine maintenance and service timing.
An hourmeter must be installed
with every Scroll compressor.
CONDENSATE DRAIN VALVE
A condensate drain valve must be
installed on any tank used to allow
removal of the liquid which will collect
during compressor operation.

NOTES:
1. Inspect and perform maintenance periodically according to maintenance schedule.
2. The maintenance schedule relates to the normal operating conditions. If the circumstances and load condition are adverse,
shorten the cycle time and do maintenance accordingly.
3. * The tension of the V-belt should be adjusted during the initial stage and inspected every 2,500 hours afterwards. Proper
belt tension for 3 HP units is 7 lbs./.16” deflection; for 5 HP units, 7 lbs./.19” deflection.
4. See Compressor Pump Manuals for replacement or service procedures.

DANGER
GENERAL
2500 HOURS - MAINTENANCE
Breathable Air Warning
The Powerex Oilless Rotary Scroll Air
Compressor has advanced scroll com-
pressor technology through the devel-
opment of a completely oilless unit.
The inlet filter on the scroll compressor
assures 99% particulate free air is
admitted to the unit. Order P/N
IP032901AV for both the 3 HP and 5HP
units. Change every 2,500 hours or
more often in dirty locations.
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, the air
compressor/pump will need to be fitted
with suitable in-line safety and alarm
equipment. This additional equipment is
necessary to properly filter and purify
the air to meet minimal specifications
for Grade D breathing as described in
Compressed Gas Association Commodity
Specification for air, OSHA, ANSI and/or
Canadian Standards Associations (CSA).
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
filtration, or inlet valves are required
on the Powerex Scroll air compressor.
1. Remove filter cover by releasing
spring clamps (See Figure 1).
2. Remove wing screw.
Do not attempt to

CAUTION
clean filter. This
filter requires replacement and is to be
replaced when contaminated.
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, flat plane or base. A
scroll set, the basic compression ele-
ment 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
180o with respect to the other so the
scrolls can mesh.
3. Clean inlet plate, filter cover and six
(6) silencer tubes using an air gun or
by wiping dry with a cloth.
DISCLAIMER OF WARRANTIES
4. Install new inlet filter (Part Number
IP032901AV) and reassemble cover.
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 whatso-
ever for any loss, personal injury or
damage.
See Service and Maintenance Video
for Visual and Audio Instructions
(Part Number IP633900AV).
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
fixed scroll, the pockets formed by the
meshed scrolls follow the spiral toward
the center and diminish in size. The
moving scroll is prevented from rotat-
ing during this process so the 180o
phase relationship of the scrolls is main-
tained. The compressor’s inlet is at the
outer boundary of the scrolls. The com-
pressed gas is discharged through the
outlet at the center of the fixed scroll
so no valves are needed.

3. Remove the fan duct shroud.
2. Rotate the compressor pulley until

This will allow regreasing of the

NOTES:
1. Inspect and perform maintenance periodically according to maintenance schedule.
2. The maintenance schedule relates to the normal operating conditions. If the circumstances and load condition are adverse,
shorten the cycle time and do maintenance accordingly.
3. * The tension of the V-belt should be adjusted during the initial stage and inspected every 2,500 hours afterwards. Proper
belt tension for 3 HP units is 7 lbs./.16” deflection; for 5 HP units, 7 lbs./.19” deflection.
4. See Compressor Pump Manuals for replacement or service procedures.
