Hey folks,
I spent a week at Arrowmont last month, and was interested in their spray
booth set up. It's vertical! See it here:

It seems that all the information on Clayart about home made spray booths
has the exhaust fan set horizontally to the flow of the spray, rather than
this booth that would pull down, or vertically.
Does anybody have an opinion on the efficacy of this set up?
Thanks! Lea in Memphis

Lea:
In the world of automotive painting older spray booths are of the
horizontal design. Air is sucked through a huge filter in the booth
doors, past the car being painted and then through more filters designed
to remove the overspray. One problem with this setup is this: as the
painter moves around the car he often ends up spraying "upwind" with all
the overspray blowing right back in his face. Although he wears a mask,
there's the problem of getting paint spray in his eyes, on clothing etc.
Another problem with this configuration is partially dried overspray
moving the length of the freshly-painted car, creating all kinds of
opportunities for problems in the wet finish.
The newer generation of spray booth is "downdraft" of the type you
call "vertical." The advantage to the automotive painter is that all
overspray moves downward through the floor instead of horizontally. This
virtually eliminates the overspray problems for the painter.
Re ceramic glazes, I don't see much difference between the two methods
with the possible exception that fewer eddy currents are generated by your
body with the downdraft approach. It would seem a downdraft booth could
be designed to be more compact, taking up less floor space.
Regards,
Fred Parker
