I’m finally getting around to making some kind of booth/filter design for cleaner paint job - does the intake side need to be roughly equal to the exhaust side ? I’ve read all about calculating proper air flow. Just trying to improve on what I do now which is box fans under my garage door. If my exhaust area is going to be 30 square feet - do I need the same for intake - my exhaust is low on back wall and intake will be on opposite wall up high near ceiling - I’m thinking it should but keep in mind it’s a garage and I’m limited due to garage design- my exhaust fans ( recent acquisitions ) are 2 big furnace fans welded together- don’t know CFM’s but they’re BIG AND HEAVY !
