I like the metal case. I made mine out of 3/4 MDF and hung it from the ceiling, yours is much more refined. Nice job!

One thing I did was use a rotary timer switch so I could leave it running in the shop when I go up for dinner & for 10-15 minutes to really scrub the air. I also put two filters on the intake, a nice HEPA inside of a cheaper paper filter to catch the big particles then the smaller ones. I don’t have a filter on the output end.

nicely done, easy replacement of filters too… inspiring.

how big is the entire unit? ho well does it work? do you feel the difference immediately? in the long run? I’m contemplating of building one of those out of ply/mdf the moment I get my hands on a blower assembly of some sort and could use the input. thanks

Hersh, the timer isn’t a bad idea, I forgot all about them. Purp, I just built the unit according to the physical size of the blower, and whats available in a generic size for furnace filters, I haven’t tried it yet in a dusty enviroment, but I see no reason why it shouldn’t work well. The price was right, and so are the filters, plus it’s portable, and could be used in home remodels. It could be built without the mobile base and hung from the cieling, I just chose to go this route because I allready have a brand name air filtration machine hanging out in the main shop, but between you and me I think filters for those things are outrageous.

I too built one for the ceiling about 4years ago out of a furnace motor over my lathe and ran duct work to the other end of the shop where I hung the blower and I had the 2 filters over the lathe. Works great. Cost me about 15 bucks, I change the filters weekly or sometimes more. They get dirty fast. I made another without duct work I’m hanging from the ceiling in my main shop. Am going to Put two filters on two sides and none where the air comes out as that end of the blower is sealed to the out side of the box. They work perfect. Cost is minimal. I think I will put timers on both I didn’t before, great idea. Yours looks professionally made. Very cool.

This is a great looking unit that will go a long way toward improving the air in your shop. This is one of the better designs that I have seen posted.

Nice job.

Well, I apreciate the comments, but I know how this place can be, alot of people here like to sugar coat other peoples achievements. I have sent basically the same information and pictures to a few local longtime friends, that are in the construction trades, and to close relation that would understand it. After almost a week, not a one reply, good or bad. Maybe it wasn’t such a good idea to have spent all that time on makeing this thing. But yet, I still continue to work on it, yesterday I bought a electronic timer switch, like what was mentioned earlier in this post, and bought some material to make a grill for the exhaust so no one sticks their hands or fingers in it. Then I’ll be freakin done with it, and I can move on to some other mindless crap that not many people care about. I’ve had the same experience with woodworking, people don’t understand the time it takes, and by the time I’m done, I’m lucky if I made $5 an hour. It gets old, REALLY OLD.

Don’t beat yourself for your acheivements! It is people like me that learn from people like you and the other SKILLED pros here. I bookmark them and hopefully will someday be able to show some of mine with pride also:o)
Thanks to you and the others for all the wisdom, ingenuity, and postings.

Well, this morning I finished it up, I mounted a electronic timer switch, and installed the grill I was working on earlier this week. Now it’s officially a done deal.
