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.

Scroll Air Compressors Tankmount/Basemount Installation HOURMETER RECEIVING THE UNIT 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. Immediately upon receipt of the scroll compressor, the unit should be inspected for any damage which may have occurred in shipment.
