Descriptions
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
filtration, 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, 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
o
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
o
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.
Scroll Tankmount/Basemount Air Compressors
TIP SEAL
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.
BEARINGS
The bearings on the scroll compressor
are regreaseable to allow extended
compressor life. Service should be performed every 10,000 hours of operation.
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.
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 any tank used to allow
removal of the liquid which will collect
during compressor operation.
Drain liquid from
tank daily.

Installation
RECEIVING THE UNIT
Immediately upon receipt of the scroll
compressor, the unit should be inspected for any damage which may have
occurred in shipment. Any shipping
damage must be immediately filed with
the freight carrier.
The compressor nameplate should be
checked to see if the unit is the correct
model and voltage as ordered.
APPLICATION
When the scroll compressor is to be
used in applications other than the
compressing of atmospheric air, please
contact a Powerex representative for
engineering and warranty information
at 1-888-769-7979.
INSTALLATION SITE
1. The scroll compressor must be located in a clean, well lit and well ventilated area.
2. The area should be free of excessive
dust, toxic or flammable gases, moisture, water and direct sunlight.
3. Never install the compressor where
the ambient temperature is higher
than 104
o
F or where humidity is high.
4. Clearance must allow for safe, effective inspection and maintenance.
5. If necessary, use metal shims or leveling
pads to level the compressor. Never use
wood to shim the compressor.
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 qualified electrician.
Installations must be in accordance
with local and national electrical codes.
Use solderless terminals to connect the
electric power source.
PIPING
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
scroll 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 connection.
5. Use flexible hose to connect the outlet of the compressor to the piping so
that the vibration of the compressor
does not transfer to the piping.
SAFETY VALVES
Tank mounted compressors are shipped
from the factory with safety valves
installed in the tank. The flow 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.
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. Confirm that the electric power
source and ground have been firmly
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 filter is properly
installed.
8. Confirm that the drain valve is closed.
9. Visually check the rotation of the
compressor pump. If the rotation is
incorrect, have a qualified electrician
correct the motor wiring.
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 qualified 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 confirming the compressor
starts as pressure drops.

This will allow regreasing of the
main bearings.
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
below & Figure 2).
Use only Powerex
genuine grease.
Pump grease gun before feeding (this
eliminates air from the grease passage
of the extension adapter. (Complete
Grease Kit Part Number IP616200AJ and
Grease Tube Part Number IP600000AV).
4. Replace plastic dust cap.
The bearings on the scroll compressor
are regreaseable to allow extended
compressor life. Service should be performed every 10,000 hours of operation.
1. Remove the V-Belts and the fan
cover.
2. Remove the air end pulley and cool-
ing fan with a gear puller (See

3. Remove the fan duct shroud.
4. Remove the three grease caps. Do
not attempt to loosen or tighten the bolt.
5. Grease all three pin crank bearings
(See Figures 3, 4 & 5 and Grease
Delivery Chart below).
The grease fitting,
located in the center of the pin crank bearing, feeds only

NOTE: Tips seals for Fixed Scroll and
Orbit Scroll have opposing seal cut
angels (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 (See Figure 7
on page 4).
Insert approxi-
mately half of the
LP tip seal and remove the tip seal to
confirm that a notch in the tip seal has
been achieved. This will prevent movement during installation (See Figure
11).
3. Repeat the same procedure for FS
or Fixed Scroll tip seal set, remove
