As Larry has already pointed out, the Fantastic Fan on Low draws pretty minimal power, about 0.3 Amps. Even with that low a power draw, the fan still manages to move a whole lot of air. It also makes a fair bit of noise while it's at it. I find there are times when I want more quiet and less breeze, so I decided to alter my Fantastic Fan to add an ultra-low fan speed switch.
I added a circuit-interrupter switch that re-routes the fan's electric supply through a 10-Ohm, 10-Watt resistor (available at most Radio Shacks that aren't located in a big shopping mall). When switched to its new low-low speed the fan moves a steady, quiet breeze that doesn't dominate conversation over the dinette table, moves just the right amount of air for a warm day or to exhaust cooking fumes so the smoke alarm doesn't go off, and consumes about 0.16 Amps.
When the interrupter switch (the black, cylindrical thing with wires leading to and from in the lower right corner of the picture below) is closed, electricity takes the path of least resistance through the normal fan wiring, but, when the switch is open, the electricity has no choice but to go through the 10 Ohm resistor to get to the fan.
The resistor is mounted using a pair of blind rivets (Pop Rivets) that secure its leads to the fan housing on either side of the ventilation opening that allows cool air to move over the resistor coils in the factory speed selector switch. This is quite important because the new resistor will get quite warm, hot to the touch, and needs to use some of the air the fan blows by to cool it.
(Yes, I know the soldering job sucks. My soldering iron wasn't heating properly. It got the job done, barely, and I replaced it after this project.)
