Hi everyone I have just re-installed my in-line extractor (the type wit
a down light in the centre of the ceiling cowell). Anyway I have now go
the timer working (previous owner connected the lives the wrong wa
round). I have mounted the fan on the wall in the loft so it pushes th
air upwards I take it this is O.K. as I always see them installed on
joist moving the air sideways if you see what I mean, and B&Q now hav
the kits in visi packs so you can't get to the instructions anymore
Also it seems to make a faint booming sound which we didn't notic
before but now it stays on you can hear it at night when in bed. Th
boom is similar to the noise of a car stereo where you can hear th
Bass of a song but nothing else and it gets a bit annoying sometimes
Mind you if I drink a few Stellas or Kronies I go to sleep instantl
but my wife doesn't see this as a long term solution
One like this, with an in-line fan, right?:
Can't see how the orientation of the fan would make any difference. Can
you tell if the noise is coming down the vent, or through the ceiling?
If the former, maybe an inline damper (www.bes.ltd.uk) would help (or
shut the bathroom door! :-) ); if the latter, maybe more ceiling insulation?
But either way, the first thing I'd try is mounting the motor on
something with a bit of 'give' to dampen any vibration: mine is attached
to a roof purlin, but with large rubber washers between the timber and
fan. Helps a lot.
