Replaced a ceiling mounted one that made the plasterboard vibrate with an inline fan. The inline fan is up in the attic and ducts through the roof. The new fan extracts 3x as much air and is much quieter.
Still need to make good the ceiling, but that’s tomorrow*'s job.
*Tomorrow in this case may not actually be tomorrow.


The main issue for mine was that it resonated with the ceiling panels, meaning there was a loud vibration that could be heard in other rooms. The noise from the new fan is just the whooshing of the air, no vibrations at all, and when the door is closed it’s almost inaudible.
