Additional Information

N/A Powerex® introduced the first dry scroll to the US oil-less compressor market in 1989.
The enclosed scroll compressors feature compact footprints, energy efficient operation, low maintenance, and environmentally friendly design, all in one complete package.

Redundancy is built into our system with our multiple pump design, eliminating the need to purchase an additional compressor.

Why Powerex®?

Powerex® has been designing and packaging systems since 1988 and has built a foundation on engineering, innovation, quality and service to become a leader in both air and vacuum systems. Because of our high level of vertical integration and a full in-house engineering team, Powerex® has the ability to customize a system to meet your air or vacuum requirements.

Technology and Innovation

N/A The scroll pump has few moving parts making it reliable and easier to maintain. The self-lubricating tip seals, and absence of a gearbox means the pump is truly 100% oil free.
As the leaders in scroll pump technology, our latest design incorporates several innovative features:

  • Main bearings are housed in durable cast iron instead of aluminum which prevents fretting and premature failure of the bearing race. This pump can be operated at 100% duty with confidence.
  • The patented bearing re-grease feature has been improved to allow maintenance from the front side of the pump, cutting service time in half.
  • The patented tip seal design yields the highest flow rates and longevity of any other dry scroll compressor.
  • The improved efficiency and cooling results in lower operating temperatures.
  • Extremely low vibration.
  • Industry first 10 hp scroll pump improves system efficiency by producing more output using fewer pumps.

Compression Principle

N/A As the orbiting scroll orbits from No.1 to No.4 position, a crescent-shaped cavity is gradually reduced, compressing the air and exhausting it through the final discharge point at the center.

Sound Enclosure Cabinet

N/A Each system is packaged in a rigid steel frame with powder coated panels and lined with sound-deadening insulation. The low noise levels are unmatched in the industry and allow installation at the point of use, while the small footprint simultaneously maximizes floor space.

Eliminate Waste

N/A With no oil in the compressor you can rest assured that you are doing your part for the environment.


N/A It's built right in with our multiple pump design, eliminating the need to purchase an additional compressor.

Energy Efficiency

N/A With the Powerex® Variable-Pump-Drive system, each compressor pump is automatically staged on/off individually based on actual system demand, maximizing energy efficiency at all usage levels. Lead compressor status will alternate every time a pump is called for – or every 10 minutes, whichever comes first - which maintains equal run hours and extends maintenance intervals.

Advanced Controls

N/A The system display shows current operating conditions, pump run status, system pressure, run hours, and alarms. The onboard diagnostic system constantly monitors the system and alerts the user of any problems or service required. Advanced control logic determines when to stage compressors to yield maximum energy efficiency.

Total System Approach

N/A We know how critical the air purity is for your application and can provide a complete solution. From individual components to complete turnkey packaged systems with air receivers, desiccant or refrigerated air dryers, filtration down to .01 micron, air quality monitoring and more.

The graph shows the relationship of daily air consumption of the plant and the corresponding electrical consumption of the compressor. When air consumption fluctuates the variable pump drive control logic is much more efficient.

The Powerex® Oilless Advantage

Benefits of an Oilless Compressor

  • Extremely reliable.
  • 100% oil free system.
  • No contamination of product.
  • No contamination of powered equipment.
  • More environmentally friendly.

  • Less maintenance – no oil changes needed!
  • No oil water separators needed.

Disadvantages of an Oil Flooded Compressor

  • Potential oil contamination of product.
  • Potential oil contamination of powered equipment.
  • Low-quality “oil free” compressors can damage equipment.
  • Potential oil contamination of environment.
  • Require additional activated carbon filters.
  • Higher level of maintenance – oil changes and filter maintenance required.
