Medium Rotarty Screw Air Compressors

Kaeser pushes the boundaries of compressed air efficiency once again with its latest generation of direct drive medium rotary screw air compressors. The value-added user benefits are immediately apparent just by taking a quick glance at the completely redesigned compressor enclosure.

Not only do they deliver more compressed air at lower power consumption, but they also combine ease of use and maintenance with exceptional versatility and environmentally responsible design.

There’s much more to Kaeser’s latest models than initially meets the eye: The new internal component layout not only ensures even greater efficiency but also allows easy access to all service and maintenance points saving both time and money when it comes to servicing.

Kaeser’s newest range of direct drive rotary screw air compressors provide significant energy savings in four ways:

  1. Fitted with the new low-speed SIGMA PROFILE airends, equipped with flow-optimised rotors. This enables the specific power to be reduced significantly more than previous models
  2. Enjoy the benefits that premium efficiency IE3/IE4 drive motors have to offer (IE4 motors fitted to select models).
  3. Kaeser’s 1:1 drive design eliminates the transmission losses associated with gear or v-belt driven systems, as the motor directly drives the airend.
  4. The newly developed PC-based “SIGMA CONTROL 2” compressor controller enables compressor performance to be precisely matched to actual air demand thereby allowing additional energy savings.
