Construction and functional principle of a turbo blower of the current AERZEN AT and TB series are simple and at the same time effective. As the air supply of modern wastewater treatment plants is clearly designed for maximum availability, high energy efficiency and long maintenance cycles, AERZEN uses for the demanding bearing system within turbo blowers neither oil nor other lubricants — but simply air.

Kaeser Compressors’ has extended its product range with the addition of PillAerator turbo blowers with magnetic bearing technology. Thanks to the direct-drive, active magnetic bearing motor and intelligent control system, the PillAerator turbo blower boasts an energy savings advantage over conventional rotary blowers up to 25%. With single unit flows up to 10,500 cfm, the PillAerator significantly expands Kaeser's solutions for water and wastewater applications.

What is a rotary screw blower?
Screw compressors delivering compressed air below 1.5 bar(g) are referred to as (rotary) screw blowers. The working principles of a screw blower are thus identical to those of a rotary screw compressor.

The groundbreaking Delta Hybrid Rotary Lobe Compressor is the result of a synergy between the rotary lobe blower and the screw compressor technologies and offers completely new possibilities by combining the technical advantages of both concepts.

The new Delta Hybrid direct driven sizes are the technological evolution of the AERZEN screw blower series. The future has just begun thanks to a super efficient newly designed stage with 3+4 rotors profile and a new drive concept for low pressure applications, a reduced footprint with side by side installation, a no-space adder Plug & Play solution with integrated starter, possibility to install IE5 motors and extended turndown ratio up to 1:5. Let yourself be surprised at how easy and cost-saving it is to generate low pressure compressed air.

Kaeser screw blowers use up to 35 percent less energy than conventional rotary blowers and even achieve significant energy savings compared to currently available screw blowers. The combination of a blower airend with high efficiency Sigma profile rotors, flow-optimized components, efficient power transmission and drive components ensures exceptional performance, guaranteed by Kaeser in accordance with the stringent requirements of ISO 1217.

The Hoffman Revolution is the world’s most advanced blower energy management system. The culmination of blower design and leadership delivers a new standard in efficiency and environmental protection. The first high speed centrifugal in its class—designed, built, and tested in the United States of America. Through advanced technologies, the Revolution delivers up to 45% energy savings, provides increased reliability with little or no maintenance, and comes factory prewired and tested in an ergonomically designed sound enclosure for plug-and-play operation.

Kaeser has been a leader in creating fully packaged blower systems that are reliable, durable, energy-efficient, and simple to maintain. Our line of Com-paK blower packages set the standard in the blower industry.
