Kaeser Compressors’ direct drive series is designed for efficiency, reliability and minimal maintenance. The units are available from 25 to 450 hp, in flows from 72 -2003 cfm and pressures to 217 psig. Kaeser’s state-of-the-art compressors feature our optimized Sigma Profile airend, patent-pending Sigma Control and the latest one-to-one direct drive technology. These are true direct drive compressors – with an oversized airend connected directly to the motor via a maintenance-free coupling for “zero-loss” transmission efficiency. Kaeser’s unique cooling air flow design significantly reduces noise levels and provides superior cooling. Plus, all units are fitted with a re-designed, high-efficiency separator system for extremely low oil-carryover – perfect for all of your instrument and bulk air needs!
