Overview
The Champion DRS125 Variable Speed Rotary Screw Air Compressor delivers 125 HP of power with advanced VFD technology that automatically adjusts motor speed (651-2151 rpm) to match compressed air demand, providing up to 25% energy savings compared to fixed-speed units. Featuring a direct-coupled G8 airend, TEFC IP-55 rated motor, and integrated aftercooler, this oil-lubricated compressor produces 520 ACFM at 145 PSIG with exceptional reliability and whisper-quiet 80 dB(A) operation. The intuitive Governor Controller with color touchscreen provides data logging, trend analysis, pressure scheduling, and iConn connectivity for intelligent monitoring and sequencing of up to four compressors, making it ideal for manufacturing, automotive, and industrial facilities where air demand fluctuates throughout the day.
