DRS Series Variable Speed Rotary Screw
Champion Pneumatic — Variable Speed Drive
10–200 HP
Variable Speed
Up to 35% Energy Savings
100% Duty Cycle
The Champion DRS Series uses a variable frequency drive (VFD) to continuously modulate motor speed and match compressed air output precisely to actual system demand. This eliminates the energy waste associated with fixed-speed compressors running at full speed during partial load periods — a common scenario in most facilities.
For operations with fluctuating air demand, the DRS Series can reduce energy consumption by up to 35% compared to a comparable fixed-speed unit. The soft-start capability also reduces mechanical stress and extends component life. Available from 10 to 200 HP.
