Bathroom extractor fan died!

[dGray]

Ive got a bathroom extractor fan that vents through a vertical pipe that sits on the fan and goes out through the roof. Trouble is that the condensation collects on the duct and runs down back onto the fan. This is what has killed it i think.

-Are any ceiling fans designed against this?

-The other option would be to put a condensation trap in the duct in the loft, but would rather not have to do this, as then i have to run a drain pipe outside somehow.

Can anyone recommend a fan that would suit? There seems to be a lot of choice ranging from £20 to £200!

I havent been able to find one that
-is designed for vertical ducting.
-has humidity on/off
-backdraft flaps.
-mounted directly above shower.
-Anything else i have missed.

Any help or buying links much appreciated.
Cheers

Could you cut a section out of the vertical pipe & replace it with a flexi hose & create a u-bend into it?

Could put in a big snake of 100 ducting, but looks a bit unprofessional surely?!

if you wrap the duct in insulation, it will not be chilled by the cold roofspace, so will not be so prone to condensation. Most loft ducts are horizontal, and you can flop loft quilt over them. As your is vertical, I suppose you could use the stuff with a plastic sleeve, and tape or tie it into place.

I have recently been using the white loft insulation from B&Q, it is not glass so does not have itchy fibres. It is made from recycled plastic soft drinks bottles and is quite pleasant to handle.
