ABSTRACT:
An impeller for a materials handling fan can be made in several different diameters utilizing a single central hub of fixed diameter. The single central hub is designed to withstand the varying stresses imposed by different impeller diameters. A circular backplate or shroudplate is welded to the hub to extend the effective diameter of the hub.
