Dag is going to build a downdraft booth and needs some ideas. Post your ideas, booth plans, photo’s and what have you for a homemade booth.
May be easiest to do it as a semi-down draft instead of a full down draft.

bloverby took some pretty good progress pix when he did his. maybe he will post them for use.
but I agree. A Semidown draft will be a lot easier.check this link out. Hope it works

First off let me say that now that it’s done I probably would’ve been just as well off having bought a used booth or a cheap new one, but at the time this seemed like the right thing to do. I thought I could build much cheaper than I could buy, but probably didn’t save a bunch in the end.
Other factors why I decided to build vs. buy: I didn’t like the idea of having to leave enough space on the outside of the booth to assemble it and change the fixtures because I didn’t want to give up the shop space. I wanted it 10′ tall so I could paint a lifted truck in it. I wanted to be able to store things on top of the booth so it needed to be sturdy. Lastly I didn’t want swing out front doors on it because I’d have to move stuff around too much to get something in and out of it.
I didn’t really have any plans I just started framing to the dimensions I wanted. The interiror dimensions are 24’long x 14’wide x 10’high. Wall framing was done with 2″x6″ lumber so I could recess the light fixtures. Interior is covered with 5/8″ firecore sheetrock. The right side wall is sistered to the exterior wall of the shop so the light fixtures wouldn’t poke out.
Started with a 7’x7′ industrial exaust wall w/ a single phase 1 1/2 hp 24″ tubeaxial fan that exits through a shutter on the back of the shop.

Then just framed up what I wanted.

Sheetrocked and hung the fixtures

Ended up building a plenum on the roof to keep all the shop dust from just landing on top of the ceiling filters

I also put frp panels around the bottom so I could hose the floor off without getting the sheetrock wet.

here, I believe code would require it to be built out of metal or concrete, but if no ones looking :whistle:

Just needs to have a 1 hour fire rating I believe. The 5/8 sheet rock does that. 😉
Probably should have fire suppression though :whistle:
I still love looking at that setup blove. makes me wish sometimes I didnt spend what i did on mine :blush: But only 2 more years of payments left :wak :wakhow ever we need a down draft design “which means suction out the floor” does it not? :unsure:
Down draft would be alot more work though.. As blove said may as well go out and buy a cheap downdraft or semidowndraft then you know no one’s going to hassle ya.. 😉
Thank’s for the link, pictures and suggestions. I will go for a downdraft, labour is cheap here and to import something is way to expensive.

Dag, post some pics of the work. Would be cool to see.

Judging by the link on down draft booth design, the one with a completely grated floor seems like it will produce the best finishes and help utilize the greatest square footage of the room? am i wrong? why do some down drafts have such narrow floor exhausts then?
The size is partially dependent on the filter size or type. Obviously a full floor grate helps with even air flow, but having the narrow grate makes it easier when using stands/moving stuff around etc.
