It is a complex problem. Mostly it depends on the design of the exhaust fan. Do a google search for Bill Pentz. The site has more info than I can relay. From what I know of the issue, I’d recommend you consider using it as an exhaust fan in your shop to keep a fresh supply of outside air and getting rid of the fine dust that keeps floating until it winds up in a pair of lungs.

I work with commercial restaurant equipment including exhaust fans and have never heard of one being used in this exact manner….I suppose on some level it would be possible but would require a lot of work and, more than likely quite a bit of custom fabrication.

the two common style fans used are one with a spun aluminum dome such as made by Jenn-Air or a squirril cage fan such as that made by Delphi. Any debris coming in contact with either of these fans will be the end of your fan.
DC fans are typically about 14 Ga. to 10 Ga. welded blowers vs. 24 to 26 Ga. punched out fans .
Big difference, they’ll move lots of air but thats about all

I agree that it would not work for a vacuum, not enough static pressure but it would make a serious air cleaner. I used a fan from a window air conditioner mounted in a 20” X 20” box, put 2 poly filters in front of the fan, used a extention cord for power. The wood was scrap 1/2” ply so the total cost was $12. I was in the commercial HVAC cleaning business so the filters were free, about 30 filters left before the cost goes up.
