High-intensity and anti-fatigue

Ring Blower is a new type device of gas source, which is most made of aluminum alloy with high-intensity and anti-fatigue. It adopt drive style with special motor and don't need any shift gear. So it has advantages of tight structure, small volume, light weight, low noise, no vibration, low power consumption, stable performance and so on. meanwhile , the disgorged gas source it don't contain moisture and oil.

  • Ring blower

  • Operating Principle

    Ring blower or exhauster increases the pressure of the aspirated gas by the creation, in the peripheral toroidal channel, of a series of vortex caused by the centrifugal thrust of the impeller. While the impeller is rotating, the vanes force the gas forward and, because of the centrifugal thrust, outwards, producing a helical motion. During this motion, the gas is recompressed repeatedly with a conseguent linear pressure increase along the length of the channel.


- Aluminum blower housing, impeller and cover: Continuous duty, Non-pulsating operation.
- Oil Free design eliminates contamination of downstream components.
- TEFC enclosure eliminates atmospheric contamination of motor windings and bearings.
- Higher-pressure and vaccum new shaft-impeller design.
- Low noise: New shaft-impeller design with the special silence material can eliminate the dB of noise which caused by cutting wind.
- Low vibration: Every impeller through computer Dynamic balancing minimizes vibration by the way, all the housing case and impeller by the CNC machine precision working.
- Light weight, small volume.
