Radial Bladed (Material Handling Fans)

The radial bladed and radial tip fan ranges with self cleaning blade configuration are designed for use where airborne solids pass through the fan. They are manufactured for rigorous industrial applications and have relatively high discharge velocities suitable for pneumatic conveying.

A range of impeller designs is available to suit various high temperature and material conveying applications.

Casings are constructed with quick release, heavy duty inspection panels and split casings, where necessary, for quick access to the impeller for maintenance procedures.
