Asset Information:
- 1.5 kW and 250 kW
- Pressure capacity from 0.8 to 156 m³/min
- Pressure difference (overpressure) up to 1,000 mbar
Your Benefits
- Low purchase cost – high efficiency
Kaeser rotary lobe blowers are unbeatable when it comes to low operating pressures and short operating times. The special OMEGA profile of the three-lobe rotary lobes ensures high efficiency. The low purchase cost pays off especially in applications and processes that require a reliable, constant air supply. - Modular and Space-Saving
Thanks to their modular design, the blower systems can be individually configured depending on the application. Anything is possible, from a simple sound-attenuating enclosure to full automation. Kaeser rotary lobe blowers are designed to be extremely space-saving, so even a side-by-side arrangement is no problem. - Rugged and Durable
A long service life and low maintenance costs are not just empty promises when it comes to Kaeser blower units. The foundation for this is laid right from the design stage. For example, all rotary lobe blowers feature straight-toothed synchronization gears, heavy-duty cylindrical roller bearings, and highly precisely balanced rotors.
Product Details
Innovative Stabling Area Concept
Multiple COMPACT blowers can be arranged side by side to save space. All maintenance and adjustment tasks can be performed from the front or from above. All valves are mounted directly on the unit. Pipe connections and intake air openings are located in a uniform position at the rear.

Robuuste opbouw – geringe onderhoudskosten
Pressure up to 1,000 mbar (o), blower unit outlet temperatures up to 160 ℃, a wide control range during variable-speed operation, and a rotor balance quality of Q 2.5—just like that of rotor discs—for smoother operation, a longer service life, and low maintenance costs are the hallmarks of the OMEGA blower unit.
The exceptionally high balance quality of the Q 2.5, combined with the rotor—which is manufactured as a single piece with the shaft end—ensures low-vibration and smooth operation. Rotor tips with integrated sealing strips make the blower unit more resistant to dust particles and thermal stress.
