You could just buy this one and save effort. But I did and I still have it up all the way anyway. I don't really use the features of the speed controller because it seems like you don't hear difference in fan speed except for like the top %4 of the rotary dial.

You need a potentiometer and rectifier. but for $14.99 I'd think of a different DYI project.

Thanks for the help dude, 14.99 is a little costly though.
Basically, i have a large in line fan that i want to run in a small area, so i don't want it running on full speed, only half would do.
How can i get the fan running at half speed, it's currently on 230v.
thanks for the help peeps.
You need to place a rheostat in series with your AC of the fan. The same thing is accomplished with a light dimmer switch you can get at lowes or HD. However, these are usually of low current capability of under 100 watts (If they are higher of course they cost more) The 300 + CFM fans can run over 100 watts so be careful. Don't buy an under-rated dimmer switch.
The previous poster is correct in saying it's better to just buy one. This is one DIY that, unless you're electrically inclined, is dangerous. Also, the price of a good dimmer is that of the referenced dimmer from HTG (which by the way is an excellent product)
the fan uses 50w, would a light dimmer do what i want?
I just want it running at half speed.
+reps peeps
Ok, i have a light dimmer in my hand now which i rated 100w.
So this will work, i'l just wire it up like you do lights?
I was told a dimmer would not work, i know know why.
Peace
