would a variac wreck a box fan?
I just bought a new 18" box fan (Patton U2-1803), but the lowest of its
3 speeds is too fast and noisy. Would I be a'hurtin' the fan to throw a variac betwixt outlet and fan and run it at lower voltage(?). I'm am electronically challenged. |

Just use the highest speed switch setting and reduce the voltage for your desired speed. Note that some fan motors will hum when controlled in this way. As an alternate method, get a fan speed control. Looks like a rotary lamp dimmer. (DON'T use a lamp dimmer.) Remove the existing switch and mount the fan dimmer in the same hole. Use the high speed wire from the switch and tape the other(s). If this is beyond you get a geek to do it for you. Advantage over the variac is convenience. -- Rich Greenberg Marietta, GA, USA richgr atsign panix.com + 1 770 321 6507 Eastern time. N6LRT I speak for myself & my dogs only.

thanks Rich for the prompt reply. Where would I find a fan speed ctl?
The large HW chains? Or Radio Shack? I'm sure the switch is much lighter than the Variac i have in mind. |

Some devices work by reducing the voltage by bleeding the current across a seperate device. IN this case the same wattage is burned off no matter what speed. Others reduce the voltage in a more spohisticated way. I think the fan controller will probably do it right. But you can only be certain if you buy it in Home Depot or the like. Buying it in radio shack means you have to know what your looking for. -- Respectfully, CL Gilbert |

Go to a large hardware store or home depot's electrical dept and ask for one. BUT If you are not comfortable opening up the fan and replacing the switch with the fan control, stick with the Variac. -- Rich Greenberg Marietta, GA, USA richgr atsign panix.com + 1 770 321 6507 Eastern time.
