We are in the process of rebuilding a spray booth. It would be more =

to have the exhaust out the top of the booth opposed to most plans I have =

showing out the back. Is there a reason that =22out the back=22 is =
preferable.
Some physics of air movement etc ? Would modify plans to exhaust out the =
back
if there are compelling reasons for doing so. Thanks a bunch. Marj.B.

Marj -
It only makes sense to have the exhaust out the back because that is the
direction the overspray is headed. Place your filters (furnace filters work
well) on the front of a small boxed-in area, with a plywood baffle spaced
three or four inches out in front of the filters, so that the air is drawn
around the baffle. That way, most of the overspray settles on the baffle
and the filters last longer. Place your fan in the roof of the spraybooth
opening into the box behind the filter. Be sure to use a vane-type blower
or fan and not a squirrel-cage blower. They tend to clog quickly.
