If you are looking for the world's most energy efficient ceiling fans, look no further. The Vari-Cyclone’s 60 inch diameter blades, designed by the Florida Solar Energy Center in cooperation with a major fan manufacturer, use “Gossamer Wind Technology”.
Vari-Cyclone is the only low voltage DC fan allowed to use these revolutionary new fan blades. The Gossamer Wind Technology blades allow the fan to produce up to 40% more air flow with no increase in power consumption, making the Vari-Cyclone the most energy efficient DC powered ceiling fans available.
Besides the Gossamer Wind Technology blades, the energy efficiency of the Vari-Cyclone fan results from a permanent magnet, TENV (totally enclosed non-ventilated) motor with long life brushes.
The Vari-Cyclone draws 0.5 amps @ 12 VDC (only 6 watts!) and 0.78 amps at 24 VDC. At 12 VDC the 3-blade fan will turn at approximately 102 rpm moving 1,476 cubic feet of air per minute when mounted at least 8 feet above the floor in an open room. At 24 VDC the 3-blade fan will turn at approximately 138 rpm moving 3,925 cubic feet of air per minute when mounted at least 8 feet above the floor in an open room.
