[quote]10,000 cubic feet per welder, with a ceiling of 16 feet with no partitions, balconies or other structural barriers.[/quote]
10Kcuft/welder sounds like alot of air, but then again it doesn't mention any sort of time frame for the exchange rate so it "may" or "may not" be alot of air...depending on the amount of time.
Are we talking about 10k cuft/welder over an hour's time or 1 week's time?.....might be getting short on clean air by the end of a week....LOL
