HOL 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. HOL 12v 56inch DC Ceiling Fan is the only low
voltage AC/DC fan allowed using these revolutionary new fan long 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 AC/DC Ceiling
Fan the most energy efficient DC powered ceiling fans available.
Besides the Gossamer Wind Technology blades, the energy efficiency of
the HOL solar DC Ceiling Fan results from a permanent magnet, TENV
(totally enclosed non-ventilated) motor with long life brushes. SPACECIT
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 HOL
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.
