Spray Booth

[dbiggied]

Personally I'd suggest one of the shaded pole blowers from Grainger. Less than $200 will get you enough fan for a big spray booth, less if you only need a small booth. Intrinsically safe fans are really intended for venting highly flammable vapors, gasoline, natural gas and such, not spray paint. None of the commercially available booths use an intrinsically safe fan, most use a shaded pole blower.

This is the one I used on my booth, it is 485cfm. 2ft x 2ft x 16" tall booth, cross flow out the back with a heater filter and 6" ducting. It works great, no overspray or odor using full size spray cans. It is a very well made, heavy duty blower that will probably outlast me.

I see your 485cfm and raise you 549cfm for about $15 less...now I know where my Christmas money is going.
