Hi,
I have a 52 inch model 22274 and a 36 inch model 22270. They are both really cool, but run really fast on their slowest (second) speed. Is there a way to slow these things down? Also are there alternative blades or something of the sort to use the fans in the winter?
Thanks,
MR |

You can get a capacitor and a 3 speed pull chain (L+1, L+2, and L+3), and wire the capacitor to low wire. As for a 52" one, I heard that 8uf will cause 15 RPMs, and 12uf will cause 70 RPMs. Or you can get a solid state speed control with minimum speed adjustment.

Yes, you can add a third speed like Jonathan said, but the RPM calculations aren't as cut-and-dry as he posted. There isn't a set RPM value depending on the capacitor. It also depends on what amp motor your fan has, how lubricated the motor is and its condition, etc. I've had fans not start at all even with a cap value higher than 7.5. Anything too low and the motor won't start on its own. I have a Reversaire in my parents' bedroom with I think either 10 or 11uf worth of capacitors crammed in it for low speed and it has to be push started on low if the blades are in a particular spot. Once it gets up to speed it runs at about 55 RPM or so.

I know what you mean about the fan not wanting to start. I had put the 52 on a dimmer switch. If the switch wasn't up to mostly full speed this fan does not move.
Also where do you find these capacitors and speed switches? Would it be a electronics specialty store or online?
Thanks for both of you guys help.

Dimmer switches are bad for the motor, unless it's a dimmer made for fans instead of lights. A normal capacitive wall controls would not work because ampage on 52" one is too high. A solid state speed control would probably work. |

Hunter makes a special three speed wall control for the original models, available on the web and ebay. I use them for both my originals and put the switch on low and the pullchain speed on low. This setup achieves a double low that works great for running slow on reverse to invert the air in the winter.
