Electric fan controller

I used one like this in the past. There's a little pot on it to adjust the on/off range. Amperage draw may require two or a dual controller. 8/16 amps would be low. SPAL fans are worth investigating too. Their flow ratings are considered more accurate. I have a single 16" SPAL that moves some serious air.

that second controller is the exact one i have been seriously considering. it looks to be a quality piece and is pretty nice looking. i will have this most likely mounted in lower corner of the core support so it will be visible and am looking for a clean as possible install.
