The innovative design of the MARWELL turbo blower combines the high efficiency of thesingle stage centrifugal blower with the easy flow control of avsd-driven blower. lt isdirectly driven by a permanent magnet synchronous motor and controlled by a variablefrequency drive. Utilizing an active magnetic levitation bearing system, it providescontactless and wear-free support for the rotating magnetic levitation bearings throughcontrollable electromagnetic forces. The magnetic levitation bearings are directlyconnected to the impeller, resulting in zero transmission loss. This ensures successfulgas delivery with no internal wear, low noise, and no need for lubrication.

Thanks to the magnetic levitation bearing technology, the rotor is levitated before theblower starts, preventing any additional wear during start and stop cycles. Thissignificantly enhances the reliability and lifespan of the machine, fitting the needs otaeration systems with diffused air and modern wastewater processes.
