Uncompromising efficiency: Rotary screw blowers with SIGMA PROFILE

KAESER’s FBS and GBS rotary screw blowers set the new standard in efficiency and space-saving design. The SFC version is equipped with an integrated frequency converter and a synchronous reluctance motor. The STC version for fixed-speed operation is now also more efficient than ever before. These innovative rotary screw blowers not only impress with their energy-saving drive concept, but also with their well thought-out and compact design, which allows all maintenance work to be performed from the front of the unit. Side-by-side installation is possible even with all electrical equipment.
