Blowers

Quiet, yet phenomenally powerful – from vacuum to low-pressure operation

Low-maintenance, quiet and efficient, Kaeser blowers generate compressed air for a wide range of different applications:

  • Pneumatic conveying of bulk materials
  • Water management – e.g. for sedimentation tank aeration and filter flushing
  • Process and cooling air for industrial purposes
  • Mobile applications – e.g. mixing, tanker and suction vehicles

We offer three different design concepts for your compressed air application:

  • Rotary lobe blowers featuring our efficient, three-lobe OMEGA rotors for minimising pulses

  • Rotary screw blowers with the energy-saving SIGMA profile – specially designed by KAESER for optimal pressure and air delivery

  • Turbo blowers with high-speed, permanent magnet motors featuring wear-proof, magnetic bearings.
