So here it is guys [and gals] the most amazing air cleaner system ever. And the beauty of it all is every thing was free and home made. I’ve had this project in mind for about ten years now but never had the materials to build it. Now i’m sure i’m not the first guy to do this but here’s my version. This is a furnace fan and moter a colleague at work gave me when he upgraded to an energy efficient unit The box is oak plywood and I hung it from the cealing about 10 inches down. I made it with two air filters so it would suck lots of air. To clean the filters I simply blow out with compressed air. It just moves a ton of air and as an added boness it blowes all the trapped warm air up by the cealing back down to the floor. I could add a deflecter plate at the air outlet on the bottom and also to make it variable speed you would have to change the moter to a DC. moter with a variable speed control switch. I think I will just leave it as is for now I couldn’t be more pleased on how it works. Maby one day i may even finnish the shop….... grumpy

Nice! I have been thinking about doing the same thing but haven’t been able to find a fan and motor yet.

That’s a very nice design and looks good. I just don’t think those filters will do a very good job at filtering the very tiny particles (like 1 micron stuff). I think most guys will do 3 filters back to back to back or something like that. Or use some sorta hepa filter???

Very nice. I have three of those that I built (not as fancy as yours…I used cheap ply scraps) and the total cost was less than the Jet model I purchased several years ago. I made 2 of mine with wheels so I could move them around the shop.
I would suggest looking into washable electrostatic filters…alot cheaper in the long run.

I really like things that are free. With just time invested, it is always worth more that any amount of money

I have a similar central fan and have considered making a regular fan in a box for hot days but like this idea better. This way it will serve both functions.

Very nice. I also had a left over central furnace fan that I used for an air filter, but I incorporated it into a base unit so it could also be used as a downdraft/sanding table. Like childress mentioned, I used 3 stacked filters from course to fine.

Mine is not as finished as yours, but it is a different end product using the same concept. Nice job!!!

Nicest looking unit I’ve seen so far : )
Let us know how it works out for you after a month or so of use.

Great job. Just like jewisbey said, I’m looking at a similiar idea in a downdraft table. This is just what I needed to make it happen. I just got done salvaging a old upright piano for hardware and wood. The back structure is going to be another workbench. Now, that workbench may have a downdraft table in it. Thanks for the idea.

Nice job. You may find it clears the air in the shop faster if you go ahead an put the deflector on it. The air should circulate around the shop, to bring the dust back to the filter. Doubling up the filters will also collect the finer dust particles. Thanks for the post.
