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.

A flexible solution for all your low-pressure and vacuum applications
Robust ZM oil-free multistage centrifugal blowers and exhausters provide you with the air or gas, pressure or vacuum you need at low maintenance costs.

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.

System controls are critical to a wastewater blower system. Without them, a system with multiple blowers operating on their individual controls will run more than necessary and result in wasted energy. Maintenance costs increase and worst of all: process performance suffers.

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.

AERZEN MultiCore series turbo blowers allow for a wide range of operation with airflow delivery of 15000 cfm and above. With over 6 to 1 turndown utilizing multiple cores, the AERZEN MultiCore series provides flexibility to users needing a wide range of flows. AERZEN MultiCore Turbo blowers utilize one user interface and come standard with one discharge connection allowing the easiest installation and operation of its kind. This addition to the Aerzen Turbo product line allows for efficient operation with largest volume airflow delivery which once again allows AERZEN customers to expect performance.

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 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.
