Paint booth/exhaust air pressure question

[64SS350]

This is for those well versed in negative and positive air pressure. I have an old fruit cellar that I boarded and sealed off years ago. It has a metal foundation vent for outside air, is approximately 6'x8'. If I vent through the door from a paint booth, would the fan be able to exhaust properly. I believe at this point, I may go with a marine engine bay exhaust fan, as suggested from another paint booth build thread.

Thanks

If the ceiling is 8' tall, you'll be venting 384 cubic feet. My marine engine bay exhaust fan runs at 170 cfm. My math says it'll take 2 minutes and 15 seconds to evacuate that space, theoretically. it's not going to be as simple as that because those fumes will linger and mix with any other open vented air entering the room. I'd connect a paint hood or as some call them a paint booth to the exhaust which will capture more of the fumes. In addition, you must wear a respirator. Those fumes will linger longer than 2 minutes and 15 seconds. I still get a slight whiff of paint odor from my enclosed booth which is 2x3x3 or 18 cubic feet after a few minutes of spraying.

Sorry, let me clarify. I will be exhausting into the closed room. I would cut a 4" hole in the door

Doesn't sound like a sound idea. Suggest looking for a way to vent to the outside and not another enclosed structure.
