That's a massive air flow for ventilation purposes. At least it would be in a greenhouse. My greenhouse is 32x54 and air flow for effective cooling is 16,000 cfm. I can run 24,000 but that only lowers temperature by about 2F.

My wet wall is 4x28ft so I'm moving 143 to 214 cfm per sq ft. The wet wall works good even at 8,000 cfm.

I'd think you should check with the company that makes the wet wall
.

Yeah its definitely a lot of air. The application is not a greenhouse, more of a factory building. However I figured I would post here because it seemed like greenhouses are one of the most common applications of these walls. Thanks for the response! I have a few similar emails in to manufacturers as well.

Wow, one air change per minute at 600,000 CFM would be a building 40'X60'X250' tall.

Haha you are correct. However we do more like one air change per 5 seconds. Our ceiling isn't quite that tall.
