Additional Information

KAESER blowers generate low-pressure compressed air for a wide range of different applications:

  • Pneumatic conveying – the efficient and effective process of using air to move bulk materials through pipelines from one point to another.
  • Water management – e.g. for sedimentation tank aeration, biological treatment and filter flushing
  • Process and cooling air – the production of blowing and cooling air for industrial purposes
  • Mobile applications – e.g. animal feed mixing, tanker discharge, suction vehicles, and airport runway cleaners)

 


 

INNOVATIVE BLOWER DESIGN CONCEPTS

KAESER offer three different design concepts for energy-efficient low-pressure air solutions:


 

Rotary Lobe Blowers | COMPACT BB-CB-DB-EB-FB-HB Series

Featuring KAESER’s efficient, three-lobe OMEGA profile rotors for minimising pulses.

Thanks to a universal design concept, these blower systems are not only individually configurable and simple to expand – they also stand out for their ease of maintenance and handling.

When specified with the optional control cabinet, KAESER rotary lobe blowers are transformed into ready-to-run, “Plug and Play” complete solutions, thus ensuring simple commissioning and reliable, economical operation.

KAESER’s tried-and-tested rotary lobe technology is ideal for applications such as the pneumatic conveying of bulk materials, filter backwashing at drinking water installations, the aeration of biofilters and pools in the aquaculture sector, municipal and industrial wastewater treatment plants and the conveyance of nitrogen.

Performance data:

  • Motor size: 1.5 kW to 250 kW
  • Delivery volume: 1.5 to 93 m³/min
  • Pressure: up to 1000 mbar
  • Vacuum: to 500 mbar

What is more, KAESER rotary screw blowers are designed to be especially compact, can be controlled remotely or automatically for trouble-free operation and are compatible with Industry 4.0 systems.

Low energy consumption, coupled with the ability to operate at 100% duty cycles, ensures that KAESER rotary screw technology pays off handsomely when it comes to municipal and industrial wastewater treatment, flotation, fluidisation and fermentation applications.

Performance data:

  • Motor size: 7.5 to 250 kW
  • Flow rate: 3 to 160 m³/min
  • Pressure differential: 300 to 1100 mbar

Magnetic Bearing Turbo Blowers | PillAerator® Series

KAESER PillAerator turbo blowers are compact turbo compressors developed specifically to provide a reliable and energy-efficient supply of compressed air in the low pressure range for aeration applications.

This future-forward turbo blower design is used in the low pressure range and is especially useful for applications with high flow rate and performance demands where maximum energy efficiency and process air availability are of key importance.

KAESER turbo blowers are used wherever process air is required in the low pressure range – such as aerobic, biological wastewater treatment, fermentation and flotation applications.

Performance data:

  • Motor size: 150 and 300 kW
  • Flow rate: up to 267 m³/min (16,000 m³/hr)

Excellent service from Kerr Compressors. We called with an issue at 4pm and their engineer, Keith, arrived by 8am the next morning. He quickly diagnosed the problem and had everything fixed efficiently with no downtime. Fast response, professional service and great communication throughout. Highly recommend
