Rotary blowers

Developed at the company’s in-house Research and Development Centre, KAESER rotary screw blower airends with world-renowned SIGMA PROFILE rotors are up to 35 percent more efficient than conventional compressor designs. Highly efficient, they feature a broad control range and ensure virtually constant specific package input power. In addition to efficiency, durability was also an essential development goal. The use of high-tech bearings and no need for ancillary equipment minimises energy consumption and enhances reliability.

To ensure that the projected savings are actually achieved during operation, KAESER quotes effective overall power consumption figures, as well as the usable flow rate, in accordance with the stringent tolerances of ISO 1217, Annexe C or E (as applicable).
