Inquiry (采购产品): Ventilation System I am looking for a portable ventilation unit for a 3500 cubic foot tent that is compatible with vapors from a 20% hydrofluoric acid/20% nitric acid solution. I need 4 air changes per hour. Do have anything that would meet this need or suggest a company that provides such equipment? **** Hidden Message ***** Tekla Staley P.O.
