The black area is where I will be placing gable vents/filters. One on each side. The air will go into the attic and pass a second set of filters before it enters the booth.
I have no way of controling fan speed. These fans are not suited for a speed controler. I am afraid of having too much air flow. I have been thinking of ways to reduce air flow. Is too much air flow a bad thing?
I really ball parked the fans CFM. I reviewed paint booths that are a similar size. They move about the same amount of air.
And I do not have a drain. I will be pushing the water out with a broom.
