ABSTRACT:
A fan rotor comprises a housing defining an interior air chamber and includes air inlet openings and an air outlet opening. A rotor blade is rotatably mounted within the chamber and includes a polygonal rotor plate disposed in parallel relation to the sidewalls of the housing and a plurality of channel-shaped blade members secured in perpendicular relation to the perimeter of the rotor plate. The rotor assembly is mounted upon a drive shaft which is rotatably connected to a power source. During rotation of the rotor assembly, air is drawn into the chamber through the inlet openings at a first velocity and is expelled through the outlet opening at a second increased velocity. The increased pressure upon the blade members helps to hold the blades in place upon the perimeter of the rotor plate. A plurality of arcuate air deflection shields extend between the side walls of the housing so as to form a cylindrical cage within the chamber for directing the flow of the air therein.
