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.
