Blowers

Quiet powerhouses – from vacuum to low-pressure operation

Low-maintenance Kaeser blowers deliver pressurised air quietly and efficiently for a wide range of applications:

  • for pneumatic conveying of bulk materials
  • in water management – for example for aeration of sedimentation tanks and filter flushing
  • for the production of blowing and cooling air for industrial purposes
  • in mobile applications – e.g. mixing, tanker and suction vehicles

We provide two different concepts to meet your requirements:

  • Rotary blowers with our efficient, three-lobe OMEGA rotors to minimise pulsation effects

  • Screw blowers with the energy-saving SIGMA profile – designed by KAESER for optimal pressure and output
