garage air filters for paint spraying?
blakep82 - 6/1/08 at 09:50 PM

anyone tried making one?

getting to the time where i'm gonna start doing more paint spraying using the compressor, and while painting my axle with aerosol cans today as the colour i wanted wasn't available to use in my spray gun, i realised just how much airborne paint there is that doesn't make it to what ever you're painting.

not really liking the idea of just extracting it outside the garage, so thought of the old kitchen hood extractors that just filter and recirculate the air. that combined with the face mask seems perfect.

so, has anyone made one on the cheap?

was thinking the filter element from a cooker extractor and a car radiator fan behind it.

any more thoughts? looking at locost here. can't afford proper filtered extractors etc

Although I have yet to try my new stuff out, I have a powdercoat setup. You should be able to make an enclosure around whatever you are painting and use a heat gun afterwards for melting the paint on. This is the theory; however it would solve your problem. The guns are cheap now.

you want a sort of welding extractor with a long tube so you can move it about where your spraying. the filter system doesnt have to be all that big then.

oh, yeah, i forgot to add that too, that way, like you say, the ducting(s) can be placed right near where i'm spraying, by hanging from the roof for example.

this was only after about 10mins of spraying... also it was only powered by me breathing, so a car rad fan sucking through a large filter should be quite good

Too much movement of air will bring up dust and debris. Not what you want around wet paint. But I get your drift.

well, i suppose it can extract to outside, as long as the paint is filtered out so it doesn't coat other cars in the street.

so, build a plastic sheeting booth in the garage, with my panel filter/fan/shroud arrangement outside the booth, and some ducting inside? ha ha, i'm probably gonna end up coating the whole nside of the garage and the cars outside with paint anyway lol

we have a spray booth at work and when we do cars (because when they are in the booth there not any room to move around them)
we have to use the mobile ducting system. we put them about 1.5-2 meters away and it works fine. and if you use a gravity fed gun you get less over spray. and a better finish.

Not if it's not HVLP you won't get less overspray. The finish will only be as good as the operator's limits whatever gun you use, suction or gravity feed.
