I posted a description of a simple spraybooth some time ago, but I know what a
challenge it is to access the archives, so here's an approximate repeat. For a
compact studio I like to use a collapsable spraybooth mounted above an existing
table or wide shelf. In any spray booth the one place you don't want to skimp
is in the fan. Get ahold of a Grainger's catalog, and buy a good 1/4 hp fan.
As an alternative, sometimes you can get used furnace fans from junk stores or
heating/air contitioning servicers. Cut and frame in an appropriate hole in
the wall, and mount the fan on the outside, with appropriate protection from
the weather. I prefer to mount the fan outside because it saves space and
reduces noise on the inside. Some fans are available with self-closing louvres
to elminate drafts when not in use. If yours doesn't have these and/or you
don't want the additional expense, just build a cover for the inside.
Mount a furnace filter element (available from most building supply or heating
and air conditioning stores) over the opening on the inside to stop the
overspray from clogging up the fan. On either side of the filter build a pair
of simple hinged swing-out vertical frames, like window shutters. With them
swung out 90 degrees to the wall, staple heavy cloth or poly sheeting over each
frame and draped across the top, creating an enclosure over the table or shelf
with the front open. When the "wings" are in the open position, just place a
length of board between the frames on the table or shelf to hold them open.
The fan should keep the air moving adequately to pull all overspray and vapors
away from you. When not in use, you should be able to fold the "wings" back
against the wall and secure them with a latch, so that the table or shelf space
is available for other purposes. If you do big work, use a lower shelf or
table to make a larger spray booth. If you make one that is REALLY big you
must use a larger fan.
