Axial Flow Fans

Witt India Pvt. Ltd. offers a range of Axial Flow Fans. A large selection of outlet positions, casing geometries, casing thickness and materials is available for the various impeller types. The following is a description of the standard product range, a very flexible production allows special requirements to be met as well.

The specific design of a fan is mainly determined by the installation in which it will be used. Beside the physical properties such as pressure, volume flow rate and temperature, the operating conditions and the installation location are of major importance (Reference DIN 24 163 for a complete description of the input parameters for a fan specification). The actual fan dimensions are mainly determined by the motors and accessories used.

Our axial flow fan range is distinguished by a large number of different standard designs. The different impeller hub-diameter ratios enable us to satisfy a very large range of volume flow rate/pressure combinations for most types of installations.

The quick selection charts/nomogrammed sheets and our dimension sheets give an overview over the most commonly used axial flow fans. In addition to the shown standard fans, we also manufacture a large number of special designs, e. g. explosion proof, pump room fans, shock proof fans, smoke extract fans, jet fans etc. In case of demand for special fans please inquire.

The fan selection graphs allow us to make a quick selection of the axial flow fans normally used at 50 Hz. They provide the fan type, size, number of poles of the motor, shaft power and sound power.
