Powerex Enclosed Oilless Scroll Air Compressors

The Powerex Enclosed Scroll Air Compressor System's main bearings are housed in durable cast iron instead of aluminum, preventing fretting and premature failure of the bearing race. The patented bearing re-grease feature has been improved to allow maintenance from the front side of the pump, reducing service time. 

As the scroll orbits, a crescent-shaped cavity is gradually reduced, compressing the air and exhausting it through the final discharge point at the center. During operation, all the gas passages are in various stages of compression at all times, resulting in nearly continuous compression and discharge.

Each compressor pump is automatically staged on/off individually based on actual system demand. Lead compressor status will alternate every time a pump is called for -- or every 10 minutes, whichever comes first -- maintaining equal run hours and extending maintenance intervals.

Each system is packaged in a rigid steel frame with powder coated panels and lined with sound-deadening insulation.
