This is the air filtration unit that I built for my shop. I used a dual squirrel-cage blower attached to a 1.5hp, 220v electric motor that I was given. I attached a timer as the activation switch so that I can set it and forget it and allow it to run after I am done for the day. The cfm rating is such that it will cycle the entire volume of air in the shop about once a minute!
The first photo is of the intake side which houses two separate filters. The forth photo shows the slots where the filters live. They just slide in and out via a sliding “door” on the bottom of the unit. The fifth photo is the exhaust side which houses one filter. I always put the least capable filter on the outside intake, backed by a more capable filter. The exhaust filter is the best that I can buy at Lowes.
It works fabulously! Although it is not that pretty…sorta like me!

Thanks for posting. I was measuring up my squirrel cage this afternoon and planning to do the build tomorrow.

The squirrel cage reminds me of An exhaust hood for over the stove. Is that what you used and if not does anybody have any insight on using one? looks like a great idea and old stove hoods might be had on Craig’s list. Mike

GOOD JOB I WISH I WOULD HAVE THOUGHT ABOUT A TIMER ON MINE , I’LL HAVE TO MAKE A CHANGE
I HAVE A 600 CFM STOVE HOOD WITH A HEPA FILTER IN A BOX LIKE THIS ONE, WORKS GREAT IF YOUR SHOP IS NOT TOO BIG

I really need to make one of these for my shop. Can these fans (or something else adequate for the purpose) be picked up inexpensively somewhere?

You can find these squirrel cages for little or nothing at garage sales. I got three of them for around 3 dollars each, all run like new and they work great. I made two blower units much like Bullgoose’s but mine are with 1 blower unit and I run exhaust across the shop to eliminate cycling good air through the unit. Mine work great except I too forgot the timer. Nice looking air cleaner you made Bullgoose. Mine are only 110 v.
