Quiet bathroom extractor?

I was quite pleasantly surprised by the Manrose MF100 from our hosts, the only downside is that you need to find a separate fitting kit. I don't rate the smaller inline Manrose ones as I've had to take several of them back to SF due to excessive vibration (one of them sounded like a petrol generator!).

I've just finished installing a Vents VKO 150mm inline fan for a customer in a small 2mx2m bathroom - whilst the fan itself is quiet, it's rated at 365m3/h and the noise of the air being sucked out of the room is a bit louder than I would personally like.

 

These inline fans have a base which you then screw to a joist or piece of batten
Any noise and vibration produced by the fan is then amplified and transmitted across the house by the timbers

Simple fix is to sandwich between the base and the timber with something soft to soak up the noise - think carpet, underlay, foam, rubber, etc

Shower pumps usually have rubber feet to alleviate this same problem but again, standing them on a piece of carpet offcut will deaden noise even further

Give it a try

 

As above, I use 20mm rubber grommets, as I have a glut usually.

 

Why's that Rulland ????

Never use them on back boxes

Only messing .....

 

Lol, I always seem to find the little blighters strewn everywhere in the van

 

They are a bit like wire coat hangers. You can never find one when you need one. But, leave two together in a wardrobe and a week later you have ten!

 

Very true Bazza, I quite often find myself working on new builds, and inevitably when the suspended ceiling chaps come in you'll find this shady looking security installer scuttling around locating offcuts of grid suspension wire.

Tbh I've got more than enough now I'm thinking of slipping all my runaway grommets onto a length for storage

 

Noticed in Edmundson's yesterday, something advertised as a silent fan.
Didn't note the manufacturer though, sorry.

 

I actually went to the trouble of mounting an in-line fan on 4 springs - bounced about a bit, but boy it was dead quiet!

I bought a XPELAIR CT4S. So quiet on normal speed i actually started fault finding assuming it had no power. Even at full speed barley noticeable
