Parents have a couple of these. They do open slowly, but technically,
there's a choice between using a magnetic solenoid which opens with
a load bang (not great in the middle of the night), or a thermal
solenoid which is silent but takes a minute or so.
The two my parents have open very smoothly, but they're only about
18 months old. Maybe when they're clogged with dust, they won't
work so well. OTOH, they're on the end of such a long length of
ducting, that there's probably no airflow anyway - they were mainly
to satisfy the BCO, where being fitted is what counts, not that they

I fitted a fan to please the BCO not long ago. I might as well have put two
10mm holes through the external wall for all the good that it did as the
ducting was that long and the owner did not want to pay for a decent inline
I have just seen the Vent Axia silent range at the wholesalers. It looks

I've not looked to see if Greenwood extractors are still around but
mine started being unreliable 2 weekends ago. It long since got
disconnected from the light and used by a pull cord only as having a
bath with a whirring fan is not conducive to relaxing bath enjoyment.
The fault was not the Greenwood which with a simple repair is
functioning again fine, but it took a morning to sort it out.
I hold up my hand at this point and admit that I had wired it in
without any isolation, so when it started cutting out I had no idea
what wiring laziness I had employed to power it. This was further
compounded by the bathroom ceiling being lowered 22 years ago and the
wires running therefore in a now inaccessible slot.
It was in the end sorted out, an FCU installed and calm returned - the
Sunday morning calm being disturbed of course by my troublesome
language on the matter.
And the fault - the screw on the line connector in the extractor had
come a little slack and erratically breaking contact. Here endeth the
story - I just do wonder how many other home wiremen are saying 'there
but for the grace ... etc'!!
