VB

Type B Vaneaxial Fan, Direct Drive

Application

The VB, Type “B” vaneaxial fan is designed for high capacity applications requiring straight-line discharge and higher static pressures. The VB can be furnished with the reversed airflow for spray booth applications, air with corrosive contaminants or high temperature applications.

The VB, Type “B” vaneaxial fan uses a one-piece cast aluminum impeller with fixed-pitch blades. No spinner is used on the impeller, which allows the use of corrosion resistant coatings and high temperature alloys. The impeller and guide vane section are designed to obtain higher static pressures and higher mechanical efficiencies than other axial flow fans. The function of the guide vane section is to improve the efficiency and the pressure characteristics by minimizing turbulence downstream from the fan and converting rotational energy at the impeller discharge into useful work.
