Powder Spray Booth Fan CFM?
I have been reading about several spray booth designs. I am looking to build a 7'x4'x6'. I am trying to figure out the size of fan to use. I intend on using 4 furnace filters, but don't want tooo much draft. I am not reclaiming powder...just want to keep it out of the shop and off me! I have seen booths ranging from 80CFM to over 1000. I wanted to have an idea before i bought a fan to avoid trial and error. Any opionions?
