<p>A fan rotor means comprising a plurality of blade elements rotatably mounted within a cylindrical shaped cage of L-shaped baffle members attached to and extending between a pair of ring shaped rims. The blade elements are securely attached at one end to a circular plate rotatably mounted within the cylindrical cage with the blade elements extending from the inside circumference of the rims toward the longitudinal center line of the cage and terminating prior to the center line so as to form a cylindrical bore within the cage. The cylindrical cage and blade members are mounted within the center chamber of a three chamber support structure with the rims securely attached to the interior walls of the center chamber. Bushings containing air inlet apertures are located within the walls such that the air inlets are in alignment with the bore and provide passageways between the outer chambers and the bore. A drive shaft is securely attached to the center of the circular plate and operationally attached to a motor for rotational movement thereof. The outer chambers contain air inlet tubes while the center chamber contains an air outlet tube such that air is drawn in the inlet tube into the outer chambers through the air inlet apertures of the bushings into the bore, and forced by the rotation of the blades through the baffle elements and on through the outlet tube.</p> |
