I can't seem to find the ACH requirements for a tractor trailer repair facility in NJ. The shop volume is 260,000 cft. The floor area is 3,260 sqft. Fuel will not be dispensed. I recall seeing somewhere that the "recommended" number of ACH is 20-30, which works out to be roughly 130,000 cfm at 30 ACH. Assuming 12 exhaust fans, each would have to exhaust 11,000 CFM. This would present some serious heating and cooling problems for the make up air. Would these run all the time the shop is occupied, or be controlled in some way? Any ideas would be appreciated.
