Ring Blowers

Industrial Ring Blower Units can be installed and mounted in any axial direction.


NOTE: Explosion-proof blowers are available.

Industrial Ring blowers are manufactured for both pressure and vacuum service. When a ring blower is used for pressure, it is usually configured for use as air supply units or compressors, while vacuum blowers are frequently used as vacuum pumps or fume/dust exhausters.

All regenerative ring blowers consist of an impeller that spins within a housing. This housing contains both an intake channel and an outboard channel; hence the name side channel blowers. When the impeller moves past the intake port, air is drawn in and trapped between the impeller blades. As the impeller continues to turn, the air is pushed both inward and outward through both channels, and this process continues until the impeller stops rotating.

It is this regenerative process that allows the side channel blower to function as both a pressure blower and a vacuum blower. While the air trapped between two impeller blades represents only a small pressure increase, the sum total of the blades, from intake to outlet, is capable of powerful continuous operating pressures.

Below are some of the applications of Industrial Ring Blowers / Side Channel Blowers.

  • Aeration
  • Effluent treatment plant (ETP)
  • Sewage treatment plant (STP)
  • Aquaculture
  • Pneumatic conveying
  • Automatic looms
  • Automatic bottling machines
  • Vacuum table
  • Plating tank agitation
  • Hopper agitation
  • Jacuzzis
  • Dental and other medical suction
  • Industrial sewing machine
  • Sock loom
  • Furnace air intake
Rugged & Reliable: The impeller shaft and casing are Aluminum cast. Side Channel Blowers are built tough for continuous 24-hour operation.

Minimal Lubrication Required: The rotating parts of Industrial Ring Vacuum Blowers are not in contact with the casing. There is, therefore, no friction during operation and thus no internal lubrication is necessary. Only the bearings need occasional lubrication after many hours of operation.

Low Noise Level: These are direct drive units with integral silencers, which ensures low noise levels.

Cleaning: When dust or residue is evident, clean the entire surface of the ring blower

Lubrication: After approximately 20,000 hours of operation or 18 months, replace the grease in the bearings
