First Looks: Variable Speed AC Fan for DIY Stir Plate or Kegerator Circulation

img_img_7320Fan 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.

Here’s a first look…

DIY Homebrew Yeast Stir PlateThe specs say this is 4.7″ square.  From side to side, I get 4 11/16″.  As you’ll see it’s large enough to hold a 5 Liter Erlenmeyer.

DIY Homebrew Yeast Stir PlateThis 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 of these 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.

I use a similar fan for recirculating air in my kegerator.  See: Kegerator Beer Line Temperatures & Reducing Foam with a Recirculating Fan

If you’re a close reader of Homebrew Finds you’ll know that I’ve been playing around with a couple of rapid prototyping-related products for use with homebrewing.  One is littlebits, the other is a XYZPrinting Da Vinci 3D Printer.  Related to the latter, I’ve printed out a few interesting things including multiple tap handle designs and a fair number of… chip clips :).  I think the technology has a lot of potential.

Anywho… there are a number of stir plate STL designs already out there.  Existing Stir Plate STL projects (at least that I’ve found) tend to use “the fan I had laying around”.  I plan to source this specific cooling fan and put together a Stir Plate design that works with it.  I like 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.   If you’re experienced designer and want to help, I’d be happy to work on this with you.  Just Email Us and we’ll get rolling.
