Thanks for your reply. Any advice on fan required.The 7m consists of 3m vertical and 4m horizontal below floor to exterior wall. Is larger outlet required. thanks gerry.
I am thinking of installing a 150mm inline fan to an internal bathroom. Could i use a reducer to take advantage of existing 100mm hole on exterior wall.It will need 7m of ducting and will have 2 elbows.The fan has 265m3 extraction rate.Is this powerful enough? thanks gerry.
