What is an EEI 2 fixed-speed compressor?

An EEI 2 fixed-speed oil-injected screw compressor meets the European Energy Efficiency Index class 2 requirements, ensuring optimal energy use at the rated operating point. These compressors are ideal for applications with constant, predictable compressed air demand.

The fixed-speed design provides simplicity and reliability with fewer electronic components compared to variable speed drives. Oil injection cools and seals the compression element, enabling single-stage compression ratios up to 13 bar with high volumetric efficiency.

Available from 5.5 kW to 261 kW in both air-cooled and water-cooled variants, these compressors cover a wide range of industrial applications from small workshops to large production facilities.
