Magnetic levitation centrifugal blower

The motor directly drives the impeller, completely eliminating mechanical transmission losses. Compared with the Roots blower, it can save energy by more than 30%, the noise is about 80 decibels, the operating life is up to 20 years, and it can realize intelligent control! Products are widely used in sewage treatment, cement, paper, textile, steel, food, brewing, petrochemical, thermal power and other industries.

  • The magnetic levitation blower does not need lubrication, and the conveyed air is clean and pollution-free.
  • The magnetic suspension bearing is completely frictionless, and the blower operates with low noise, which will not affect the surrounding office and living environment.
  • Compared with Roots blower, it can save energy by more than 30%.
  • The maintenance of the magnetic levitation blower is simple, only need to replace the filter regularly.
  • The motor adopts direct drive, small size, light weight and space saving.
