Scroll Basemount Compressor
Operating & Maintenance Manual
Description
The Powerex Oil-less Rotary Scroll Air Compressor has
advanced scroll compressor technology through the
development of a completely oil-less unit. The Powerex
design permits a continuous 100% duty cycle. No oil
the Powerex scroll unit.
Compressor Cycle
The Powerex oil-less rotary scroll air compressor is
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
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
scroll so no valves are needed.

Intended Usage
This Powerex Oil-less Scroll set is intended for use
as part of a system. The compressor set provides
compressed air from the oil-less scroll pump when the
electric motor is powered. The set includes the pump,
and a pressure relief valve. Do not operate the set with
place and that the inlet air system is not restricted.
Operating the scroll pump with a restricted inlet will
result in pump damage. Do not modify or remove the
Powerex check valve or relief valve. The relief valve
will open if the set is accidentally operated with an
isolation valve closed.

Check to make sure isolation valves are open. Open the pressure relief valve on the
compressor. Stop unit and correct valve installation or setting.
Check to make sure that the pump is open to intake air. If isolation valves are used
on intake and are accidently closed when pump is running, pump damage can occur.
This is not covered under warranty. Powerex recommends using a three way valve if
isolation is desired so that no matter the valve position, a path to intake air is always
