Magnetic Suspension blower 10HP-400HP, levitates its rotor electromagnetically on active magnetic bearings, eliminating the lubrication system and delivering 100 % oil-free, frictionless operation. With contact-free magnetic bearings and a direct-drive high-speed permanent-magnet synchronous motor, its overall efficiency is 25–40 % higher than that of Roots blowers and 10–15 % higher than multi-stage centrifugal blowers.
