I am creating a "room" in my shop that could/would be used for priming and possibly painting.

I have been waffling for months as to how big (how many CFM) of a fan to install in outside wall

and how many square feet of filtered air do I need coming in from LARGE shop, that I can heat/warm up ??

Also in placing filter(s) over exhaust fan how much does that cut down on the CFM rating ????

and lastly what about explosive proof fans versus any other type ????


Thanks
