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.
