Blower fan VDN-32BK with electric motor and soft-start device

Single suction centrifugal fan with hollow blades. It is intended for supply of clean air to the furnace of boiler units at the temperature of transported air not more than 100 . The fan structurally consists of a guide apparatus, necessary for regulating the operating parameters, spiral casing, impeller, which serves for energy transfer to the flow from the drive motor and running gear. In the process of medium movement in the impeller, the flow is dynamically influenced by the blades and is involved in rotational motion. This results in a change in the momentum of the transported medium and an increase in its potential and kinetic energy. The increase in flow energy is expressed as an increase in static and dynamic pressure.
