Fan with included AC Wiring and Variable Speed Control.
I picked this cooling fan up primarily to put together a Stir Plate design that works with it. I chose this model because… 1. It’s a good size (4.7″ square), 2. Is already wired for AC and, 3. Includes a variable speed function.
I’d call this just a hair under 1″ thick
This thing is all but begging to become a stir plate. I put four of these rubber bumpers in the four corners (to hold the erlenmeyer in place and give it a little bit of clearance) and then put four magnets in the center. Those just stuck on there with magnetic force and they ended up deciding to stack themselves two high. It’s kind of hard to tell with this photo, but this is a 5L Erlenmeyer Flask with 2L of water with a vortex using that setup. I’m not suggesting this as a final design. I’m only that this fan is a great candidate for conversion.
This photo shows the magnet/rubber bumper setup
I use a similar fan for recirculating air in my kegerator. See: Kegerator Beer Line Temperatures & Reducing Foam with a Recirculating Fan
