DESCRIPTION
GENERAL
Powerex Scroll Enclosure Air Compressors are designed to
supply continuous oil-free air by using the most advanced
scroll technology. These turn-key packages are extremely quiet
and offer electronic control that will reduce electrical power
consumption.
The Powerex Oil-less Rotary Scroll Air Compressor has
advanced scroll compressor technology through the
development of a completely oil-less 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. The
compressor is virtually maintenance free.
The Powerex Oil-less 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 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 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 entering gas is
trapped in two completely opposite gas pockets and
compressed as the pockets move toward the center. The
compressed gas is discharged through the outlet at the center
of the fixed scroll so no valves are needed.

SCHEDULED MAINTENANCE
Per OSHA regulations, lockout
compressor system from all power sources BEFORE
performing any maintenance.
MAINTENANCE INDICATORS
The PUMP MAINT indicator will activate when the running
hours of any pump accumulates to a required maintenance
interval. The system is designed for multiple pumps to accumulate hours evenly and for maintenance intervals to be approached simultaneously. To prevent nuisance PUMP
MAINT indications, all applicable maintenance counters
should be reset after the required maintenance actions are
performed.
INTAKE FILTER
1. Remove the small rear access panel.
2. Remove the wingnut on the filter housing and drop the
cover down. Remove the element without removing the cover
from the enclosure cavity.
3. Clean the inlet filter element with compressed air or
replace with a new element.
NOTE: Never clean filter element with solvents or water.
VENTILATION SCREEN
1. Remove the ventilation screen located at rear of the unit.
2. Clean with compressed air or soap and water if necessary.
feeding to eliminate air from grease passage of the needle
adaptor.
NOTE: Each pump of the grease gun equals 0.65g of grease.
The volume of grease is less after the 2nd pump since some
of the grease supply will remain in the grease passage.
Use only Powerex genuine
grease. Pump grease gun before
INSPECT V-BELT TENSION
1. See page 9 of Operation Manual, IN562802AV.
GREASE COMPRESSOR BEARINGS (Figure 7)
1. Remove the plastic dust cap from the airend.
2. Move the compressor pulley until the grease fitting is
visible through the dust cap hole.
3. Use a grease gun extension adapter to engage the grease
fitting and supply the proper volume of grease as indicated on
the grease delivery chart. See chart below.

1. Remove fan duct (2) (Key #5)
2. Remove the nuts and bolts and then the fixed scroll from
the air end.
3. Grease all three pin crank bearings as indicated on the
grease delivery chart above.

SCHEDULED MAINTENANCE (Cont’d)
REPLACE TIP SEAL
1. Remove intake hose
2. Remove the discharge hose.
3. Remove nuts and bolts that secure fixed scroll.
4. Remove the fixed scroll housing.
5. Take out the old tip seal from the orbiting scroll housing
and fixed scroll housing, see Figure 8.
6. Remove the old dust seals from fixed scroll, see Figure 9.
Install the new tip seals and dust seals in the stationary and
orbiting scroll housings in the following manner:
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 9.
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 8 and 9).
2. Insert so that new LP tip seal will contact closely with HP
tip seal inside Scroll Groove.
10HP - 20HP Scroll Enclosure Air Compressors
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 8).
3. Repeat the same procedure for FS or Fixed Scroll tip seal
set, remove both the dust seal and the backup tube located on
outermost side FS set.
4. Insert new backup tube in FS in the 6 o’clock position (See
figure 10).
NOTE: In order to distinguish between the tip seal for Fixed Scroll and the tip seal for Orbit Scroll place the tip seal as shown
below then view from the arrow direction and refer to the figure on the right.

SCHEDULED MAINTENANCE (Cont’d)
5. Insert new dust seal on the backup tube (See Figure 11).
6. After replacing tip seal set, reassemble Fixed Scroll set to
the Orbit Scroll. Tighten nuts and bolts temporarily and
confirm if pump pulley rotates smoothly by hand and tighten
them firmly. Tightening torques are in the chart below:
Bolt Torque
First Second
175 in lbs. 265 in lbs.
NOTE: Assemble so that dust seal and tip seal will not drop
between Orbit Scroll set and Fixed Scroll set.
