I rethought this flow thing. This is entirely based on my opinion. I would think if you are using a single 4” pipe with an area of 12.57 square inches from your machines. Then you should have a opening at least 3 times that area for the exit of your cabinet. To calculate the area of a pipe you take the diameter of the pipe multiplied by pie so 4 times pie is 12.57 SQ inches or 12.56637061435917 to be exact. 12.57 sq inches times 3 is 37.71 square inches. So you could build your exit 4×9.4275. As long as your exit is larger than three times the size of your pipe it seams like there wouldn’t be a restriction in flow that would effect the performance of your collector. What would Jet say if asked about the air flow needed to run this collector?
