Rotary lobe blowers up to 250 kW

Rotary lobe blowers – Impressive reliability

Rotary lobe blowers from KAESER with the OMEGA Profile impress with their exceptionally durable construction. 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:

  • 1.5 kW and 250 kW
  • Gauge pressure flow rate from 0.8 to 156 m³/min
  • Gauge pressure differential up to 1000 mbar

Your benefits:

  • Low investment costs – high efficiency 
    Rotary lobe blower systems from KAESER are unbeatable when it comes to operations with low working pressures and short running periods. The special OMEGA Profile featured on KAESER’s three-lobe rotary lobe blowers guarantees high levels of energy efficiency. Low investment costs pay off particularly quickly in applications and processes which require a reliable supply of a constant air volume.
  • Modular and compact 
    Thanks to their modular design, KAESER blower systems can be configured individually, depending on the application in question. Anything is possible, from simple sound enclosures to a fully automated system. What is more, KAESER rotary lobe blowers are designed to be particularly compact, meaning installation side-by-side poses no problem at all.
  • Robust and durable 
    When it comes to KAESER blower blocks and airends, “long service life” and “low maintenance costs” are no mere catchphrases. The foundations for these qualities are laid down during the manufacturing stage: All KAESER rotary lobe blowers feature precisely machined timing gears, highly durable roller bearings and precision-balanced rotors.

Product details

Innovative installation concept

To save space, multiple COMPACT blower units can be installed side by side. All maintenance and installation work can be performed through the front or top of the unit. All valves are mounted directly on the blower unit. The pipe connections and cooling air apertures are located at the rear.

Robust construction – low maintenance requirements

The OMEGA blower block delivers pressures up to 1000 mbar(g), block discharge temperatures up to 160 °C, a broad control range with speed-controlled operation, Q 2.5 rotor balancing for quieter operation, extended service life and minimal maintenance requirements. 

An extremely high rotor balancing quality of Q 2.5, combined with the rotors’ single-piece design including the shaft ends, ensures a vibration-free, low-noise operation. Rotor tips with integrated sealing strips ensure the blower block is more resistant to dust particles and thermal stress.
