I ask a friend who installs heating and cooling for a used squirrel cage blower. Couple of day later he show up like a true friend with a blower in hand. He subscribed to the theory more is better and brought me a commercial blower. I had plan to make me a air-filtration system. A year later, I found the time this weekend. I thought before I went through the trouble of building a box, I need to make sure this blower even operational. So took an old power cord and wire it to the blower. When I plugged it to the wall plug, the blower roar to life, spewing a years worth of shop dust in to the air. Once I caught my breath, I was pleasantly surprise that the blower ran perfect. With no more excuses I drew up a air-filtration system in sketchup . So this weekend I finished! The box is 3/4 poplar I had left over from another job. On the in take of the box I install a frame to hold a two filters ( 24 X 24).With such a large blower I went with the larger filters. I built a hatch on the side to access the filters.On the out take side I installed another filter. (12×15). So the air is filtered through three filters. I hung the box from my ceiling with eye bolts and hard wired it to the house with a timer. So now as I head up stair from my shop my filter system runs for an hour clearing the air. The finish size is 25 1/2’’, high, 36” long and 24’’ wide.I put a like to my sketchup model. I ran the filter for about 30 today and the filter already had a brown tint to it. Better in the filter than my lungs!

Is that 110 or 220? I’ve got a 220 blower from my own house that I kept, but I don’t have 220 in my shed :(

@TelescopeMaker, You can get a converter/reducer to pull it down from 220 to 110. I bought mine at the heating and air place I got my blower from. The blower was free but I paid the guy to wire mine cause I didnt know how. The reducer cost like $20, paid him $15 to wire it for me.

WooHoo! I like it. This will definitely be my next project. I built my $2 dust collector for my machines but still end up with a LOT of dust floating around in the air. Thanks for a great idea.

The blower is 110…..It puts out a pretty strong exhaust . So I positioned the intake toward the main work area of my shop and the exhaust away from the work area. I am hoping the set up will clean the air, while at the same time no cause a dust storm with the exhaust.

Very nice build. I had a few of those large blowers cross my path, and they were all dead as a doorknob… So I bought mine. I would rather have built one…

I built one for my shop as well, they are great. Mine is smaller, it takes 12”x24” hepa filters, on two sides. Draws air in on both sides, and exits out the front.. you don’t realize how much dust they collect until you look at the filters after a busy day.
This one belongs on monster garage.. it would likely pick a small child up and stick him to the filters..LOL

Great job, I know you will enjoy it.

wow, that looks like one heck of a filter :)

I’d probably find a shop cat stuck to the filter!

That’s about as good as it gets !

Nice job !

You think about putting a timer—multiple hour timer—instead of an on/off switch ?

Nice to have the thing run for a couple hours, after you leave the shop.
