ABSTRACT:
Efficient traditionally appearing ceiling fan blades with aerodynamical upper surfaces and wide tip ends for ceiling fans with blades formed from plastic and/or wood and/or separately attached surfaces that run at reduced energy consumption that move larger air volumes than traditional flat shaped ceiling fan blades. And methods of operating the novel ceiling fans blades for different speeds of up to and less than approximately 250 rpm. The novel blades twisted blades can be configured for ceiling fans having any diameters from less than approximately 32 inches to greater than approximately 64 inch fans, and can be used in two, three, four, five and more blade configurations. The novel fans can be run at reduced speeds, drawing less Watts than conventional fans and still perform better with more air flow and less problems than conventional flat type conventional flat and planar upper and lower surface blades.
