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.

Kaeser has been designing and manufacturing superior industrial machinery since 1919. With over 100 years of manufacturing experience, we pride ourselves on upholding our traditions of quality and craftsmanship. Our reputation for reliability, energy efficiency, and excellent service has helped us grow into a global leader in blower and compressed air technology.

Aerzen’s AERprocess Dissolved Oxygen Control is an integrated solution for controlling the dissolved oxygen (DO) concentration in the activated sludge treatment process and the blowers used to generate the process air flow requirement.

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.

Aerzen Rental provides best-in-class packages engineered for aggressive rental environments with on-board VFDs, remote monitoring, and outdoor builds with sound attenuating enclosure as standard.

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.

Capacity bottlenecks or production losses are scenarios feared in every company and require a fast and efficient solution. AERZEN offers 24/7 solutions to overcome problems arising in the supply of oil-free air for various application cases.

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.
