This Manrose CF234 Ceiling Exhaust Fan can be ducted up to 3 meters. Anything longer would probably result in a considerable loss in capacity. When ducting please remember to keep the duct run as straight and tight as possible.
The CF234 ceiling fan only requires an installation space in a roof cavity of 141mm. It is a good choice if you have a particularly small roof space. The fan is side ducted and will connect to 100mm ducting. See the additional information tab below for more information. The Manrose CF234 exhaust fan comes with three selectable speeds:
High Speed – 205m3/hr
Mid Speed – 142m3/hr
Low Speed – 95m3/hr
