SIGMA PROFILE - more air for less power


Sigma Profil

The KAESER SIGMA PROFILE, introduced in 1975 and continuously optimised, brings power savings of up to 15 percent over conventional rotary screw profiles.

All KAESER airends are equipped with rotors having this energy-saving profile. They are operated at their best specific working point to ensure highest energy-efficiency.

  • Up to 15 percent energy is saved by the optimised performance of the SIGMA PROFILE and excellent flow characteristics of the inlet channels. 
  • Very long operational life due to precision-aligned, top-quality rolling bearings. The bearings used are designed for generous reserve. 
  • High reliability resulting from close tolerance production on high-precision grinding machines. 
  • The airends are designed and produced in-house by KAESER.
