Thom, Funny thing, I went and read that after I sent the email. Thanks for the direction, though. The plenum is fresh air supply. I've done many paint booths before, but I believe that this is the first one that hasn't had the plenum as exhaust. It's just throwing me for a loop. I saw that 90 sf as well in the annex and was wondering why since EH calculated systems are allowed to be 100sf.

EH 90SF head spacing, Are there any EC EH heads? If so go with their listing. Specifically speaks of Exhaust ducts and spray areas, because supply ducts wouldn't collect paint residue, but a re-circ might, and would need protection. So is it a fresh air supply or a re-circ?

I need the help. Thanks, Bk -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Knight Sent: Wednesday, September 24, 2008 11:47 AM To: [email protected] Subject: Spray Paint Booth Forum, I have a couple of questions in regards to spray paint booth for a MAACO facility. 1) The spray paint booth has an interior dimension of 13'1". Are two branch lines required, or can one be used? Per 13 EH max is 12', is there anyway to use one line? 2) This booth has a plenum between the top of its structure and the interior ceiling. This plenum is for air intake. Per NFPA 33 air recirculation units are to be protected. Does the air intake fall into this category, and will it require sprinklers? 3) This booth has booth intake and exhaust ducts. Do both types need sprinklers or only the exhaust?
