Hi Everyone,
I purchased a house a year ago and noticed that the bathroom fans exhaust to the attic (its an older house). I want to avoid drilling holes in the roof since I just had it done. So I wanted to run the exhaust hose 30 feet to a gable and exhaust out that way. The smaller bathroom is 8Lx4Wx8H and the bigger bathroom is 10Lx6Wx8H. I was going to get a 110cfm fan for the bigger bathroom and a 80cfm for the smaller bathroom. As for the duct i was going to use a Insulated flexible duct R6 silver jacket. Is 30 feet to long? Also would a centrifugal fan be better then the ceiling one? Any help would be greatly appreciated.
