Medical Scroll Enclosure Systems

WhisperAIR™ Sound Enclosure Cabinet

Powerex’s trademarked oil-free enclosure systems offer the lowest noise levels in the industry. 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.

Oil-less Scroll Pump Technology

Our innovative scroll technology is completely oil-less, extremely quiet, and energy efficient. 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 10hp scroll pump improves system efficiency by producing more output using fewer pumps.

Energy Efficiency

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