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.

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.

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.

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 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 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’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.

Aeration is the heart of most industrial and municipal wastewater treatment and we have a new, cutting-edge solution.
