Rotary screw compressors with 1:1 direct drive

Superior efficiency

With Kaeser's one-to-one drive, the airend is directly connected to the motor via a maintenance-free coupling that eliminates transmission losses. Kaeser's direct drive rotary screw compressors range from 25 hp - 650 hp, deliver outstanding performance, and increase energy savings. 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.

Options include:

Our fluid-injected rotary screw compressors are the perfect choice for industrial compressed air applications. Not sure which model you need? We're happy to help you determine the right solution. Contact us to get started.

Your advantages

  • Exceptional efficiency:
     IE3 and IE4 motors with premium efficiency performance provide additional energy savings.
  • Longer service life:
    Electronic thermal management dynamically controls the fluid temperature of our ASD - HSD series for increased energy efficiency. The ETM prevents internal condensation build up, eliminating a common cause of lubricant degradation.
Low life cycle costs
Life-cycle costs

Our comprehensive approach to life cycle cost management: Superior efficiency, easy operation, service-friendliness, and a global service and consulting network with fast response times.
