Developed in the company’s in-house Research and Development centre, the KAESER screw blower airend with the world-renowned SIGMA PROFILE is up to 35 percent more efficient than conventional airend designs. In addition to efficiency, durability was also an important development goal. The use of high-tech bearings and no need for ancillary equipment further minimises energy consumption and also enhances reliability.

Pure efficiency with the SIGMA PROFILE DBS, EBS, FBS series Developed by KAESER in the early 1970's, the company’s proprietary SIGMA PROFILE rotor technology revolutionised energy efficiency in the rotary screw compressor sector. Further refined in the KAESER Research and Development Centres in Coburg and Gera, this high-efficiency compressor technology is now also available for users in the blower sector.
