Aluminum fan

Combined with an aluminum wall housing, an aluminum shutter and a vinyl-coated wire guard, American Coolair’s AL aluminum fans will provide years of trouble-free and corrosion-free service. AL fans feature all-welded angle frame construction and the panel has a deep spun orifice for maximum efficiency. The blades are bolted to a cast aluminum hub, which also serves as the fan pulley.
