An axial blade impeller for an industrial fan assembly includes an impeller hub assembly with a plurality of impeller blades each extending from a hub assembly outer surface to an outward blade edge opposite the hub assembly outer surface and having a first lateral blade edge and a second lateral blade edge opposite the first lateral blade edge. A first cover plate disposed on a first end of the impeller hub assembly has first cover plate arms extending outward, with each of the first cover plate arms secured to the first lateral blade edge of one of the impeller blades. A second cover plate disposed on a second end of the impeller hub assembly has second cover plate arms extending outward, with each of the second cover plate arms being secured to the second lateral blade edge of one of the impeller blades.
