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.
Not exactly easy, as the part of the attic I was working in is not boarded, so lots of twisting to get angles for screwdrivers etc. The existing ducting was long enough that it easily accomodated the new fan. Snips and zip-ties FTW. Took an hour and a half and I managed to strip the head of the last screw I put in to secure the new fan into the bracket holding it onto the rafters. That is also future me’s problem.
