Direct Drive Rotary Screw Compressors

Kaeser's direct drive rotary screw compressors range from 25 hp - 650 hp and deliver outstanding performance. Kaeser uses oversized airends specifically selected to produce the required output in flow and pressure. Compared to compressors using small, high speed, gear-driven airends, the one-to-one drive provides significant savings. With Kaeser's one-to-one drive, the airend is directly connected to the motor via a maintenance-free coupling that eliminates transmission losses. Options include: T-models: Integrated refrigerated dryer for high compressed air quality (ASD, BSD, CSD, and DSD series) SFC Models: Variable speed drive (VSD) to efficiently meet varying demand
