Description
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 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. The
compressor is virtually maintenance free.
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 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 fi xed scroll so no valves are needed.
