Description
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 filtration, or inlet valves are required on the
Powerex Scroll air compressor.
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 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 orbiting
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 orbiting 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 fixed scroll so no valves are needed.
Safety Guidelines
This manual contains information that is very important

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 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
G 7.1 - 1966, OSHA 29 CFR 1910. 134, ANSI 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 ARE VOIDED, AND POWEREX
DISCLAIMS ANY LIABILITY WHATSOEVER FOR ANY LOSS,
PERSONAL INJURY OR DAMAGE.

Maintenance
DRY TYPE INLET FILTER
2500 Hours - Maintenance
The inlet filter on the scroll compressor assures 99%
particulate free air is admitted to the unit. Change every
2,500 hours or more often in dirty locations.
1. Remove filter cover.
Do not attempt to clean filter. This filter
requires replacement and is to be replaced
when contaminated.
2. Install new filter element and reassemble cover.
CLEAN COMPRESSOR FINS
2500 Hours - Maintenance
1. Remove the FS cover (see page 6).
2. Clean compressor fins using compressed air.
3. Put the FS cover back.
GREASE COMPRESSOR BEARINGS
10,000 Hours - Maintenance
Per OSHA regulations, ALL power must
be locked out before performing any
maintenance.
This service should be performed by an
authorized Powerex Service Center to
avoid failure.
OS Bearing
1. Remove the plastic dust cap (See Figure 1).
2. Rotate the compressor pulley until the grease fitting is
visible through the dust cap hole (See Figure 1). This will
allow regreasing of the OS bearing.
3. Use a grease gun extension adaptor to engage the
grease fitting and supply the proper volume of grease
as indicated on the grease delivery chart (See Grease
Delivery chart on Page 2 and on Figure 1).
Use only Powerex genuine grease. Pump
grease gun before feeding. This eliminates
air from the grease passage of the extension adapter.
4. Replace plastic dust cap.
Greasing Pin Crank Bearings
The bearings on the scroll compressor are regreaseable to
allow extended compressor life. Service should be performed
according to the Maintenance Schedule on Page 2.
1. Remove the fan duct (2), part number 5 on Pages 6 and 7.
2. Remove the nuts and bolts and then the fixed scroll (FS)
from the air end.
3. Grease all three pin crank bearings (See Figure 2 below
and Grease Delivery Chart on page 2).
4. Replace the fixed scroll and fan duct (2). See the Bolt
Torques chart on page 5.
TIP SEAL SET REPLACEMENT
5,000/10,000 hours - Maintenance
Per OSHA regulations, ALLpower must
be locked out before performing any
maintenance.
The “Tip Seal Set” is a replacement part for SLAE03EB,
SLAE05E, and SLAE05EHP air ends. Please read these
instructions thoroughly and carefully to ensure correct
replacement.

Replacement
1. Remove the FS nuts and bolts and then FS set from air
end.
2. Remove LP and HP tip seals from Fixed Scroll set and
Orbit scroll set. Using the tip of a ball-point pen at the
start will make it much easier to remove (See Figure 4).
3. Remove all dust from the Scroll wraps and tip seal groove
with clean cloth or compressed air before inserting the
new tip seals.
Maintenance (continued)
NOTE: Replace tip seal on SLAE03EB and SLAE05EHP at 5,000
hours when operated at 145 psig.
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 operating @ 115 psig.
Confirmation of the Parts
1. Confirm if the tip seal set you purchased is correct for the
air end you are repairing. See part number 12 on Page 7
for tip seal set and corresponding pump model number.
One tip seal set contains all of the items in Figure 3
below.
2. Confirm if the following parts are included (See Figure 3).

Inserting tip seals
NOTE: Tips seals for Fixed Scroll and Orbit Scroll have opposing
seal cut angles (See NOTE and explanatory diagram below).
Insert tip seal so that the lip of tip seal is on the bottom of
seal groove and inner side of involute and the direction of lip
faces the center of involute (curving spiral). See Figure 5. This
is to be done for both FS and OS sets.
Use caution not to tear or distort lip.
1. Insert new HP tip
seal from the center
section for OS or Orbit
Scroll so that there
will be no clearance at
the tip (start) section
(See Figure 5 and 6).
2. Insert so that new LP
tip seal will contact
closely with HP tip
seal inside Scroll
Groove (See Figure 4
on page 4).
Insert approximately half of the LP tip
seal and remove the tip seal to confirm
that a notch in the tip seal has been created. This will prevent
movement during installation (See Figure 7).
3. Repeat the same procedure for FS or Fixed Scroll tip seal
set, remove both the dust seal and backup tube located
on outermost side FS set.
4. Insert new backup tube in the FS Scroll in the 6 o’ clock
position (See Figure 8).
5. Insert new dust seal on the backup tube.
6. After replacing tip seal set, reassemble Fixed Scroll set
to the Orbit Scroll. Tighten nuts and bolts temporarily
and confirm if crankshaft rotates smoothly by hand and
tighten them firmly. Tightening torques are:
NOTE: Assemble so that dust seal and tip seal will not drop
between Orbit Scroll set and Fixed Scroll set.
