100% pure oil-free suspension bearing, no mechanical friction, service life can reach semi-permanent. No mechanical noise, no mechanical vibration, simply conveying air.
Since 2000, it has been widely used in large and medium-sized industrial machinery. Compared with oil bearing, its simple structure can start stably at high temperature. It has the best suspension ability in permanent magnet high-speed motor and does not need a complex sensor system.
The most efficient centrifugal blower in the world at present. Even after another 100 years, RAETTS air bearing blowers with national level IE4 level of energy efficiency is still the standard of the energy-saving blower.
