These two new blowers are energy efficient
With a flowrate of 18 to 72 m³/min and pressure differentials from 0.3 to 1.1 bars, as well as a selection of motors ranging from 45 to 110 kW, the FBS rotary-screw blower continues the success story of its smaller sibling, the EBS, while setting new standards in terms of energy efficiency, space-saving design and automation. The SFC version (photo) is equipped with a frequency converter and a synchronous reluctance motor — a slip-free design that combines all the advantages of high-efficiency permanent-magnet motors with those of robust, service-friendly asynchronous motors. Thanks to variable speed control, the flowrate can be adjusted as required and a control range of 1:4 is achieved, allowing exceptionally dynamic operation. The STC version is now equipped with an energy-saving IE4 Super Premium Efficiency motor, which reduces energy consumption. — Kaeser Kompressoren SE, Coburg, Germany
