REDUNDANCY, It’s built right in with our multiple pump design, eliminating the need to purchase an additional compressor.

SAVE ENERGY, With the Powerex Variable-Pump-Drive system, each compressor pump is automatically staged on/off individually based on actual system demand. Energy efficiency is maximized at all usage levels. Lead compressor status will alternate every time a pump is called for, or every 10 minutes, whichever comes first. This will maintain equal run hours and extend maintenance intervals. 

ADVANCED CONTROLS 10-40 HP, 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.
