Q: Is a 7700 cfm fan adequate for a booth the size of the one in your video?
A: In terms of power, yes; a 7700 cfm fan is adequate for that size booth, but that assumes a small exit port paired with a well designed booth. Remember, a booth is a funnel that channels a large volume of air (from where you stand) through a small opening (the filter covered fan.) That means you will be standing in clean air because the airflow will go smoothly from behind you, past the piece you are spraying, through the funnel and out, as opposed to creating turbulence that just blows fouled air around the shop. It’s that directional flow that is critical, and that’s the crux of why you make a spray booth.
It’s also why you use a turntable. Once you make a booth, it is vital that you spray only in one direction; toward the fan. Only a turntable will allow you to spray all sides of an object and still be facing only one way.

Gentle reminder: A modest donation to this finishing blog can keep it going to help others. Thanks!
