This is something that’s popped in and out of mind over the last couple of years. Has anyone heard of, or had an experience with building a little spray booth/box hooked to a dust collector to draw in the fumes? Of course, I don’t want all of that going into my pipes and hoses, and don’t want flammables flying past the motor, or gumming up the impeller, but with the right filter, or filter combo, perhaps there’s a way to entirely cleanse the air of things like aerosol spar urethanes, or HVLP varnish coats.
I have a woefully small shop. I’ll post about it here someday with pictures, and it’s smallness will fill you with woe. I have to double-up on things, and one problem I have, encountered again just this afternoon on my lunch break while coating a lazy susan with spray-on spar urethane outside, is wind. It is always windy midday here. It quite literally never hasn’t been. It’s something about neighborhood life in west LA. There are just always whirling breezes making good spray coats in my back yard mostly impossible. I can’t spray in the garage, because it’s so tiny. I tried it once, and the fume-fogged garage was too noxious to enter for a whole day, and the film of the spray settled on everything. I had to do a lot of wiping down of things.
My DC pulls in a good amount of air, though, and spraying smaller things up on a workbench with something like 2’x2’ hood leaned over the area, with some side walls to channel the airflow over the piece would catch everything. I’ve taken to setting up a hood in this fashion when random-orbital sanding a piece, taking off the collection bag and just keeping the vent pointed toward the hood. The shop air stays quite clear.
I’m curious to know if something like this has been done to create spray booths, if there are standard drawbacks to be aware of, and if any standard [Home Depot?] filter or combos thereof can really catch it all without killing the airflow too much. Thanks!
Edit: I just did some deeper digging after posting this, and stumbled onto airbrush spray booths for hobbyists, and at the bottom of e.g. this model's page are replaceable filters in the $30-$60USD range. Seems a good place to start, though the booths are a bit pricey. I feel I could rig something myself that’s more suited to my space, and probably even collapsible/winchable into the rafters. The models seem designed to blow the air right back into the room with you, so perhaps the filters do completely clean the air.
