For wastewater treatment systems in either communal or industrial treatment plants, bioreactors or flotation plants, operators seeking a reliable supply of compressed air with differential pressures up to 1100 millibar and a flow rate from 5 to 160 m³/min need look no further than Kaeser’s rotary screw blowers from the CBS to HBS series, featuring a power output of 7.5 to 250 kW. Up to 35% more efficient than conventional rotary lobe blowers, they also offer significant advantages in terms of energy efficiency and blower air availability over many turbo blowers in this power range. Kaeser rotary screw blowers particularly excel when operating at 100% duty cycles, where they are especially well suited to generating process air for the purposes of aeration in water treatment, flotation and fluidisation processes and in bioreactors.
The latest highlights from this model series are the FBS, with a flow rate from 18 to 72 m³/min, pressure differentials from 0.3 to 1.1 bar and motor power outputs from 45 to 110 kW, and the CBS, featuring a power range from 75 to 160 kW, flow rate from 22 to 104 m³/min and differential pressures up to 1100 mbar.
High-efficiency motors
Kaeser’s latest generation of variable-speed rotary screw blowers are equipped as standard with synchronous reluctance motors – highly efficient drive motors that are able significantly to boost the energy efficiency levels of units equipped with a frequency converter. The special rotor design used in this new generation of motors makes them extremely robust and durable. Furthermore, all Kaeser blowers are delivered as complete, turnkey machines including a Sigma Control 2 smart controller, which makes them particularly well suited to Water 4.0 applications.
Turbo blowers now available from Kaeser
The latest member of the Kaeser family is the PillAerator turbo blower, suitable for flow rates of 50 to 275 m³/min and differential pressures up to 1.3 bar. These extremely energy-efficient machines stand out for their intelligent design, whereby smart magnetic bearings operate completely wear-free, proactively controlling the position of the rotors. Furthermore, they are completely safeguarded against any potential power failure. As the bearings operate completely independently of speed, the machine is always ready for restarts, whilst the use of a cooling concept for core components that does not rely on ambient air ensures a particularly long-lasting and trouble-free operation.
Efficient control – the icing on the cake
For a modern, professional blower station, the Sigma Air Manager 4.0 master controller is an absolute must. Not only does it ensure optimal operation of each individual blower unit, but also that all units are operating together as a system in the most energy-efficient manner possible. Upon specifying the required setpoints for intake flow rate, standard flow rate or working pressure via the process control system, the Sigma Air Manager 4.0 then orchestrates the most efficient possible air supply and optimal load operation for each individual blower within the system. The operating data provided by SAM can further serve as a basis for an energy management system as per DIN EN ISO 50001 and DWA A 216.

Established in 1919 as a mechanical engineering workshop, Kaeser Kompressoren is a family-owned business and today is one of the world’s leading compressor manufacturers and compressed air systems providers. Kaeser’s production centres are located in Coburg (main plant) and Gera, Germany. The company approximately 7000 employees worldwide.
Kaeser’s comprehensive product range comprises stationary and portable rotary screw compressors, stationary and mobile reciprocating compressors, vacuum pumps, rotary blowers, rotary screw blowers, turbo blowers, filters, dryers, air tools and accessories. Furthermore, Kaeser’s state-of-the-art compressor control systems with advanced IT technology take compressed air efficiency to the next level and beyond. Both users and the environment therefore benefit from the consequent energy-savings.
Subsidiaries and authorised partners in over 140 countries ensure that users are able to enjoy all of the benefits that the very best in compressed air engineering has to offer. Key markets include the EU, the United States, Latin America and the Asia-Pacific region. Kaeser owes its enviable reputation not only to the exceptional efficiency and quality of its products, but also to its reliable field service. More recently, the other industry-leading services offered by the company – such as operator models for compressed air stations, concepts within the framework of Industry 4.0 and predictive maintenance – have increasingly moved to centre stage.
Kaeser’s many years of strong growth and expansion are directly attributable to its passion for innovation and strict quality standards. Both are driven by the hard work and dedication of its employees, whose expertise, combined with ongoing professional development, keep them attuned to the very latest technology. The company’s opening-up of key global markets in recent years has also created many additional jobs and secured existing ones, both in Germany and around the world.
The company is headed by Thomas Kaeser, Dipl.-Wirtsch.-Ing, grandson of the company’s founder, and Tina-Maria Vlantoussi-Kaeser, Dipl.-Wirtsch.-Ing.
