I got a dual industrial blower unit given to me and I'm going to make a
downdraft sandign table with it.
I've been all over the FAQ, google, etc. and while I've found a few
insights but not really enough to get going with. I like this design:
But my blower is essentially TWO of what thay guy has and while I could
conceivably separate the 2 (they share a common shaft which I'd have to
cut and re-locate the end bearing), I'm thinking that more airflow is
I think I need more filter area.
I've seem commercial kits that have filters all the way around, but my
kind of blower isn't conducive to such a design.
The only other idea I have is to build a carcass, put the blower in the
bottom and put a 'ceiling' of filters above it, covering the entire
inside area of the carcass, and then put the swiss-cheesed work surface
My concern with that is that it doesn't have the sloped surfaces that
other designs incorporate which seem to be there to equalize the airflow
at the edges.
Anyone care to share their thoughts ?
