Project Information

3/4 hp. Air handler from a local A/C company: Free. You just have to ask sometimes, which I did. Only took one stop and bam had a free squirrel cage with working 110 motor.

1/2 ply all around, 20×20 household filters, one 700. the other 1200, whatever that means other than one being more expensive than the other.

glued and screwed it all together, made a separate baffle which holds the actual fan cage and cut a hole in the skin for the clean air exhaust ,where I used a standard household diffuser, which I found later would have been better with no bent blades to direct the flow. Better off with it going straight out the back I think now.

Wired it up with a manual 3 speed switch. Googled for way too long looking for a an actual 3 speed rotary switch, and this works just fine. Lots cheaper too.

Now just need to paint it, or not…and hang it on a wall. The wife doesn't want it hanging from the ceiling over her Miata. I think there's a trust issue here.

Works very well, and much more powerful than the 1/4 and 1/3 horse motors you usually see on ebay.

Those work quite well. I have 3 in my shop that I built from squirrel cage motors and also have a Jet unit I bought over 3 yearsd ago. My homemade ones have wheels on them so i can easily move it around the shop.
One suggestion…buy a permanent washable filter as they are alot cheaper in the long run.

Great Idea Scott! I like it a lot!! Is there a reason your wife don't want this hanging over her Miata?
