Inquiry (采购产品): Exhaust Fan cover I am looking for information and a possible product suggestion for an exhaust fan cover or damper (perhaps actuated) approximately 28"x28" to fit onto my existing pool area fan. The current fan runs continuously as the former louvered cover is non-fuctional and we would like the capability of switching the fan on and off for the winter months. **** Hidden Message ***** Rob Van Dine 13901 USA Company: YWCA Binghamton E-mail: robvandine@hotmail.com **** Hidden Message ***** robvandine@hotmail.com
