One-to-one Direct Drive Compressor for Maximum Efficiency and Reliability


Kaeser Compressors Inc. announces the latest additions to our direct drive rotary screw compressor line – the new FSD series compressors in 350-450 hp models. Available in flows from 1250-2003 cfm and pressures to 217 psig, FSD compressors are designed for efficiency, reliability, and minimal maintenance.

These state-of-the-art units feature our optimized Sigma Profile airend, patent-pending Sigma Control system and the latest one-to-one direct drive technology. The FSD units are true direct drive compressors with an oversized airend connected directly to the motor via a maintenance free coupling for maximum efficiency.

Units are now available in either air-cooled or water-cooled models. Kaeser’s unique cooling air flow design includes a powerful radial fan that significantly reduces noise levels and provides superior cooling. All models are fitted with a re-designed, high-efficiency separator system for extremely low oil-carry over. And for applications with varying demand, the FSD is also available with variable speed drive.
