I am getting started on building my paint booth. It will be modular, 12 x 24 ft, with 6 x 8 ft panels that will be fastened together. I've got a 5000 cfm exhaust fan, and was planning to use it to blow air into a plywood plenum, through a dozen intake filters, and then exhaust out the other end through exhaust filters.
This will be inside my 40x50 shop that has heat and AC. It will pull conditioned shop air in, but I am uncertain if it can be just be exhausted through the exhaust filters into the shop, or if I need to make it a negative pressure booth, pulling air out and exhausting it outside.
I was thinking of using zipwalls to allow me to enter/exit, and also for the truck parts to enter and exit.
I would sure appreciate any info/recommendations anyone to help me figure this all out.
