Inquiry (采购产品): Industrial exhaust fan My name Jim Potts w/ J. R. Simplot Company @ Lathrop, Ca. I need on a wall mounted w/ movable louvers exhaust fan.. Air flow is approx. 2400 cu.ft/hr., that is 6 air changes per hour. This would be a 12” fan. The fan will be mounted in the wall w/ a metal frame. Fan construction should be carbon steel with out the zinc coating (Galvanized). The fan is for providing ventilation in building and eliminating motor exhaust. This a metal building which house two fire pumps, electric and diesel.. Thank you: jim potts **** Hidden Message ***** jim potts 95330 USA Company: J. R. Simplot Co.
