Manrose CF100T Centrifugal Bathroom / Toilet Extractor Fan with Timer for 100mm/4" Ducting

Excellent extractor fan - my previous fan was a cheap axial fan from a local trade merchant which didn't really work that well and was noisy/rattley. This one is the same size as that axial fan but sits far further from the wall (approximately 4 cm or so). It is much more effective however, it has a different sound (more of a 'whoosh') but it's not too loud and you can see it pulling the air through far better than before. These centrifugal fans have much more 'push' than an axial fan and are particularly well suited if extracting along ducting or against any kind of resistance. This fan clears our bathroom so much quicker than before and was easy to install so highly recommended!

The noise takes a little getting used to. It's not the dull whir of the conventional fan extractors but more a high pitched whine you get from a hoover or jet engine but at a lower decibel. I did notice it to start with but now I hardly notice it at all compared to my older and much more distracting fan. The power is also pretty impressive too. Damp in my bathroom has been an issue and this things sucks out the air in the room at an impressive rate and at a power that allows it to fling out the moist air along a long vent to the outside wall (around 15"). The installation is pretty straight forward, although I found the front guard distorted rather easily and required a bit more finessing with the screws than a more solid guard would have provided but a very minor niggle for a good quality vent at a solid price.

I bought this to replace a simpler Manrose fan that has died after a good number of years of service. The connections are identical so fundamentally it was not hard to install. There were some fiddly steps but that had more to do with it being fitted to the ceiling other than the wall, and more so the location of the power supply cable in my ceiling. Some modding to allow the power cable to be threaded through was required but it went in in the end. It is quiet enough for me and I am happy with it.

Bit noisy

Good product, good value

the fan is noisy when running and does a mediocre job of extracting the steam. the big problem with it the backdraft doors that are suppose to keep out drafts. the doors keep opening and closing when the fan is off due to a updraft when wind goes over the house, so there is a constant clicking as they open and close. To fix this I am going to have to go into the attic and see if they can be removed from the fan.

Replaced a Manrose quiet/slim fan and the difference is night and day. It is definitely noisier - a lower pitched hum - but it really extracts a lot more moisture from our en-suite (via ceiling mount and a somewhat twisted ducting pipe). The product is also very deep and sticks out from the ceiling a fair distance. One thing to note is the mounting points are not in the same place as the Manrose quiet fan, just in case like me you were hoping for a swap-in/out. Very happy with it's performance though, massive difference!

Old manrose fan was a little noisy after 20 years so swapped it. If its a swop, look at the new fan where all the fixings are. The circuit board cover is a little flimsy. Its a quality fan, but if you need it to rotate when switched, buy the basic type which is cheaper. all the dimensions are the same, but doesn't have the run on option when switched off. If its a new fan for a new application, get an engineer in, its a lot of work and you may need ducting
