Ring blower increase the pressure difference through a series of vortices, which are created by the centrifugal force in the peripheral side channel, hence they are also called “side channel blower”.

WORKING PRINCIPLE

bs-type-showfou-ring-blowers-side-viewCaused by the rotation of the impeller, the gas trapped within the chambers is starting to rotate, while the centrifugal force is forcing the gas into the narrow side channel. This causes spiral shaped vortices in the side channel. These vortices cause the pressure of the gas to rise, along the whole length of the side channel. The rotating parts of the ring blower do not touch the housing, eliminating friction and the need for lubrication, which would cause machine failure. The pressure build-up is entirely without oil, there is no pollution of the gas.

“SHOWFOU Ring Blower is directly driven by TEFC IP54 Grade F insulation electric motors.As standard equipment, silencers are internally mounted on the discharge and suction side, thereby reducing noise levels considerably. Being highly resistant to corrosion,  all blower and motor parts are made of cast aluminum. Along with the motor fan, the ribs on the blower housing contribute to great heat dissipation.Our ring blower is designed for air transferring as well as pressure or vacuum generation. The use of aggressive and toxic media, the air of high humidity and temperature of over 40°C is subject to further clarification. The conveying of explosive gases is prohibited. If the medium to be conveyed contains solid particles or other pollution, they are to be removed before entering the blower by a filter, or similar device on the suction side.

An increase in the volumetric flow or the pressure could be achieved by connecting two blowers :

  • If connected in series, the pressures are added, whereas the volumetric flow remains the same.

  • If connected in parallel, the volumetric flow rates are added whereas the pressure remains the same.

FEATURES

  • Aluminum blower housing, impeller, and cover.

  • Continuous duty, non-pulsating operation.

  • Low noise and vibration, inlet and outlet have the internal silencer.

  • Could be mounted in any plane.

  • The oil-free design eliminates contamination of downstream components.

  • TEFC enclosure eliminates atmospheric contamination of motor windings and bearings.
