DURAVOLT AC DC solar ceiling FAN is the most energy efficient solar ceiling fans, look no further. It is av12v 56inch DC Ceiling Fan blade diameter is designed with Gossamer Wind Technology that makes it blow fast and makes the room cool. DURAVOLT 12v 56inch DC Ceiling Fan is the only low voltage DC fan allowed using 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 DURAVOLT DC Ceiling Fan the most energy efficient DC powered ceiling fans available. Besides the Gossamer Wind Technology blades, the energy efficiency of the DURAVOLT solar DC Ceiling Fan results from a permanent magnet, TENV (totally enclosed non-ventilated) motor with long life brushes. DURAVOLT solar DC Ceiling Fan draws 0.5 amps 12 V (only 6 watts) and 0.78 amps at 24 V. At 12 V 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 V 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. For maximum efficiency use the optional Speed Control in conjunction with the DURAVOLT solar DC Ceiling Fan. The Speed Control makes clockwise and counter-clockwise rotation possible. Without the Speed Control the fans operate at one speed determined by the input voltage. The Speed Control outputs an adjustable 12 to 30 volts DC from an input 12volts DC. It has a voltage control potentiometer with an on – off switch and an output voltage reverse switch to reverse the fan’s direction. It is overload protected by input and output self-resetting fuses.
