Kaeser Compressors EBS 410 rotary screw blowers

Kaeser Compressors has expanded its range of EBS series rotary screw blowers with the launch of the EBS 410 models, designed especially with water industry applications in mind. The EBS 410 blowers offer a flow rate of 10–40 m³/min and pressure differentials from 0.3 to 1.1 bar, as well as a selection of motors ranging from 22 to 75 kW.

More efficient than previous models, the standard STC version is now equipped with an energy-saving IE4 super premium efficiency motor that further reduces energy consumption and therefore running costs.

The SFC (Sigma Frequency Control) version is equipped with a frequency converter and a synchronous reluctance motor — a slip-free design that combines the advantages of high-efficiency permanent-magnet motors with those of robust, service-friendly asynchronous motors. Due to variable speed control, the flow rate can be adjusted as required and a control range of 1:4 is achieved, which allows dynamic operation and optimised efficiency.

With both versions, power transmission from the motor to the air end 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%. Kaeser claims to guarantees performance in accordance with the strict tolerances of the ISO 1217-C/E standard.

The models come in two different sizes — up to 37 and 75 kW respectively. They can also be installed side by side, and the 37 kW version has a footprint of only 2.2 m².
