Oil Free Piston Units - Powerex - SOS - Scroll Operating System
Scroll Compression Principle

Rotating the orbiting scroll within the stationary scroll causes a crescent shaped compression cavity. This crescent shaped compression cavity moves around the point of symmetry reducing the cavities size and exhausting the compressed air out the center of the stationary scroll. No other technology offers fewer moving components and lower bearing loads than the Powerex Scroll Compressor.

SOS, a Scroll Compressor Operating System


SOS - Scroll Operating System

SOS maintains the required air while minimizing the operating cost. If the air demand varies throughout the day, so does the number of compressors operating. Multiple compressors eliminate down time during maintenance and offer backup for the user.
Introducing SOS, a Scroll Compressor Operating System that doubles as your accountant. Earning your business the highest rate of return by providing air at the lowest possible price. This uniquely designed operating system controls the operation of Multiple Oilless Scroll compressors, ranging from 10 to 20 horsepower.


So quiet you can't believe it's running. The enclosed Scroll Air compressors are surrounded with a sound dampening steel enclosure that absorbs the sound and provides an aesthetically pleasing appearance.


No need for a separate room, the room is included. Combining the low operating noise with the small footprint, this compressor can be installed almost anywhere.


Once a year or 10,000 hours. SOS reminds you of when maintenance is needed.
