Centrifugal Fan Flexible Connection

Every running centrifugal fan generates vibrations. If there is no isolation between the fan flange and the ductwork that vibration will be transmitted directly to the rigid duct system. This results in increased noise throughout the factory, stress on the duct joints and mechanical load on the fan's own bearing housing. Centrifugal Fan Flexible Connection solves this problem. When installed at both the fan inlet and fan outlet, it absorbs vibrations before they enter the duct, accommodates thermal expansion of the ductwork and corrects minor installation misalignments. So that no axial forces ever reach the fan casing.

Materials are selected according to your process environment. EPDM is used as a belt material for general applications up to 135°C. Silicone is used in high-temperature fan applications up to 260°C. PTFE is specified for corrosive chemical environments and temperatures up to 538°C. Flanges are available in carbon steel, galvanized steel, SS304 or SS316L depending on the fan series and installation environment. Centrifugal Fan Flexible Connection is available in both round and rectangular cross-sections and is supplied with backing bars. A metal flow liner can be added inside where airstream suction or friction resistance is needed.
