Rotary Screw Compressors

Belt Drive to 22 kW


  • KAESER screw compressors with V-belt drive provide outstanding efficiency and reliability. KAESER was one of the first compressor manufacturers to introduce the V-belt drive system. The KAESER drive is characterised by an automatic tensioning device that ensures constant transmission efficiency and reduced maintenance costs. SX series models are equipped with a flat drive belt that does not require additional tensioning.
