I'm planning to fit a bathroom extractor fan, i currently have a high level
air brick/vent in the wall with a grill over it.
Is there a proprietry kit that will either let me fit a fan into a say half
of a grill & retain some of the natural free ventilation, or a grill that
will take a fan completely?

Is there anything particularly wrong with using the existing vent?
presumably an electric fan will give far greater air flow than the vent ever
did, & save me bashing holes through etc.

Not that I've ever seen. If they are out there they'll be pricey,
standard fans are only about £20.

Nope.

Yep, got it in one. You'll need to line the existing duct though with
a pipe for the new fan.

What would the lining entail? normal ducting pipe, or something box like
with an adapter, to fill the void & then connect a fan onto?

I did this - I took the grille off, made up a wooden plate (painted mdf -
sorry!) to fit over the exisiting hole which then supports a surface mounted
bathroom extractor fan. If you don't fit a self closing louvre on the
outside then you shouldn't significantly impede normal ventilation.

A piece of soil pipe or similar 100mm round pipe. Wickes have ducting
kits, and I seem to remember seeing it by the metre. You'll have to
fill the remaining area in the existing vent duct yourself.

thanks, thats the sort of idea i've got, i didn't know if still having some
free ventilation would reduce the efficiency of the fan, i don't want to
just blow air around the vent, but looking on vent axia website they seem to
do some sort of fitment for single/double airbricks that may work, although
a home made plate sounds easier ＃.
