ABSTRACT:
Several embodiments of high efficiency fans having lightweight housings supported and interconnected with their impellers by star-shaped frames disposed inside the fans, or in other words inside the areas defined by the fan housings, are illustrated herein. The use of a support frame inside the fan permits a much lighter construction than is possible with an outside frame, because the support members are in tension rather than compression and bending forces on different portions of the housing balance each other. To further minimize weight, the fans include hollow support rings and diffusers that receive air from the fan impeller and are partially supported by that air against fan pressure loads.
