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 fi ltration, 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, 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 orbiting
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 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 fi xed scroll so no valves are needed.

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 fi t
the air compressor/pump with suitable in-line safety and
alarm equipment. This additional equipment is necessary
to properly fi lter and purify the air to meet minimal
specifi cations for Grade D breathing as described in
Compressed Gas Association Commodity Specifi cation
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.
