Industrial Rotary Screw Blowers


A more efficient design for industrial blowers using rotary screw technology

More air for your money

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. 

 Air at the press of a button

Kaeser's screw blower, one of Processing Magazine's 2014 Breakthrough Products of the Year winners, is a fully integrated turn-key package complete with high efficiency motor, silencer, inlet filters, starters/drive and a sound proofed steel enclosure. The standard Sigma Control 2™ monitors a full complement of sensors and its expanded communication features include an Ethernet port and built-in Web-server for remote monitoring and email notifications for service and alarms. Communication interfaces such as ModBus, Profibus, Profinet, and Devicenet are available to provide seamless integration into plant control/monitoring systems. These units are designed, built, and tested to meet international and domestic performance and safety standards, and are available in both STC (wye-delta start) and SFC (Variable Frequency Drive) versions.
