ABSTRACT:
A fan construction of the type having a hoop configured hub provided with fan blades. The hub has apertures adjacent the blade roots. A viscous drive carries the hub. Rotation of the fan causes a pressure differential between the two ends of each hub aperture thus forcing an airflow radially outward to assist in cooling the viscous drive.
