摘要

A forward curved blade impeller for an industrial fan assembly includes an impeller hub assembly, an impeller baseplate mounted on the impeller hub assembly and having an annular shape, a first impeller ring having an annular shape, and an impeller blade deck having a plurality of first impeller blades extending between, circumferentially spaced about and secured to the impeller baseplate and the first impeller ring. A plurality of reinforcement bars extend between, are circumferentially spaced about and are secured to the impeller baseplate and the first impeller ring. Additional impeller blade decks and impeller rings may be stacked above the first impeller blade deck and first impeller ring, with the reinforcement bars extending from the impeller baseplate through intermediate impeller rings to a topmost one of the impeller rings.
