Centrifugal Blowers/Fans

Usha Die Casting Industries specialises in the manufacture of custom- designed Centrifugal Fans and Blowers under the Symbiosis brand. These are manufactured out of MS, CS, SS, FRP lined in impeller types like backward curved and radial blades. The radial bladed impeller is non-clogging and is suitable for heavy dust loadings and materials handling. Backward curved impeller designs generally represent high efficiency and cost effective centrifugal fans for both clean air and light dust loads.

Design of a centrifugal fan is mainly determined by the geometrical conditions of the installation. The following gives an overview of the most common designs. In addition they manufacture a large number of special designs to customer specifications.

• Direct Drive: Most cases one attempts to use a direct drive, which is more compact and has less part to be serviced and in most cases is cheaper than other designs.
• V-Belt Drive:When fan speeds that cannot be achieved with direct drives or there are installation specific requirements, a V- belt drive is used.
• Coupling Drive: For accommodating a starting torque or variable torque e.g. when using the fan for material transport to be dampened while protecting the motor, then a drive using an elastic coupling is being used.
