Screw blowers up to 5650 cfm

Kaeser's rotary screw blowers: more air for your money

Kaeser screw blowers are available in sizes up to 335 hp and flows to 5650 cfm and use up to 35 percent less energy than conventional rotary blowers and even achieve significant energy savings compared to currently available screw blowers. Screw blowers also have significantly better isentropic efficiencies than lobe or multistage centrifugal blowers. The combination of a blower airend with high efficiency SIGMA Profile rotors, flow-optimized components, efficient power transmission and drive components, ensures exceptional wire-to-air performance and oil-free air, guaranteed by KAESER in accordance with the stringent requirements of ISO 1217.

  • High-efficiency and low-maintenance blower systems – dual shaft SIGMA blower blocks
  • Optionally available with wye-delta starter (STC) or frequency converter (SFC)
  • Plug-and-play complete package with power supply, SIGMA CONTROL 2 controller.

Municipal and industrial wastewater, flotation, and fluidization applications stand to benefit from using Kaeser screw blowers. Since these applications require blowers to run constantly, energy efficiency is a key consideration.

Your advantages

  • Maximum package efficiency:
    The combination of SIGMA Profile rotors, optimal motor-to-blower power transmission, and minimal pressure losses for all components ensures exceptional all-round efficiency.
  • Minimal pulsation in the connected process piping:
    Special silencers covering a wide frequency range significantly reduce machine and piping sound, making our screw blowers quieter than lobe, multistage centrifuges, and other screw blowers.
  • Reduced downtime:
    Highly durable components ensure reliable operation. The smart design eliminates the need for auxiliary devices (e.g. for sealing or cooling). Numerous sensors allow remote monitoring of operating status.
