I have to retro-fit an exhaust duct to a previously installed, un-ducted bath fan. The orientation of the fan would require about 180 or so degrees of bend, and about 8 ft. of straight run. (The Broan website is down, so I cant look up the maximum values.) Anyone have any insight?
Redsy: If Broan is down, try Nutone, the stuff is basically the same, or close for your purposes. Off the cuff, I think your numbers would get by, or can you change the fan to 80CFM. John
