Rocky Creek Hydro now makes two types of DC ceiling fans: the
Vari-Fan and the Vari-Cyclone.
Vari-Fan
The Vari-Fan comes with all the hardware that allows it to be mounted close to
the ceiling or hung from its 4" down rod (longer rods available - see below).
Each fan comes with 5 blades and blade arms leaving the
choice up to you whether to mount
 the fan with 4 or 5 blades. Each wooden fan blade is reversible with a
light oak finish on one side and a dark oak finish on the reverse side - again allowing you to choose the
finish that will go best with your decor.
The Vari-Fan is a brand new fan (not a retrofit) made of
light but very durable ABS plastic, cast metal blade arms plated with a bright brass finish, and balanced
wood blades. A heavy duty permanent magnet motor - drawing only 0.4 amp at 12 or 0.8 amp at 24 V DC powers
each fan. The Vari-Fan comes with all mounting hardware requiring only a screwdriver and pliers for minor
assembly and hanging.
The molded housing of the Vari-Fan comes with a matte black
finish. It will not dent or scratch easily, or be subject to corrosion in humid climates. Painting
instructions are included with each fan. Estimated time to prepare and paint the Vari-Fan is one hour.
Vari-Cyclone
The Vari-Cyclone uses
"Gossamer Wind" technology in the design
of its blades allowing the Vari-Cyclone to produce up to 40% more air flow than the 5 blade
Vari-Fan
described above while using the same amount of energy. The motor and motor housing are the same for both fans.
The Vari-Cyclone can be mounted close mount position or on a 16" down-rod included with the fan. This fan has
four 60" blades and is painted all white. Painting instructions are included as is all necessary mounting hardware.

Variable Speed Fan Controls
Recommended by Rocky Creek Hydro for their ceiling fans,
these are very quiet, dependable speed controls. They will work equally well on
both 12V or 24V battery systems. On either battery bank voltage it allows the
fan to run from 12V to 28V DC. i.e it acts as a "voltage doubler" on
a 12V battery bank and a speed control on a 24V battery bank. The control also
incorporates a reversing switch with a center "OFF" position allowing
easy duplication of an optimal speed setting. This control is internally
protected from wiring the input with incorrect polarity. It also features
output short circuit protection. Each unit comes complete and ready to install
with a mounting plate for a single gang box. A 48 VDC version is available for
operating a RCH fan on a 48V battery bank. .

These fans are very popular for winter air circulation. They move 105 cubic feet of air per minute. The outside dimensions are 4.75'' X 4.75''. You can mount them in the corner of a doorway to circulate woodstove heat around the house. The 24V fan uses .35 amps. and the 12V fan uses .55 amps. We have 120V AC fans that use 14 watts.
