The EBS 410 rotary screw blower from Kaeser is based on an oil-free compression blower technology, designed especially with water industry applications in mind. The blowers have a flow rate of 10 to 40 m3/min and pressure differentials from 0.3 to 1.1, as well as a selection of motors ranging from 22 to 75 kW. The SFC version 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 flow rate can be adjusted as required and a control range of 1:4 is achieved, which allows exceptionally dynamic operation.
The STC version is now equipped with an energy-saving IE4 Super Premium Efficiency motor that reduces energy consumption and therefore costs, making the STC version more efficient than ever before.
With both versions, power transmission from the motor to the airend takes place via loss-free and maintenance-free gearing, which results in an up to 8 % improvement in specific power compared to the previous model. The complete machine achieves an isentropic efficiency of up to 80 %.
