How to connect ducting to this odd shaped tile vent?

[Andy.T]

Hi all,

We're in the process of replacing an underperforming extraction fan (read all about that over at the electrics forum!).

In tackling it I've removed the existing ducting to look at what I'll need to get move from 4" to 5" ducting. I was surprised though to find that the recently installed roof tile vent is neither compatible with circular or rectangular ducting. It's hard to take a good photo of it but the aperture (when viewed from inside the loft) looks a little like this...

...and the circular ducting you see in the top picture was just vaguely duct taped next to it, but not forming a good seal.

Does anyone know what sort of tile vent that is likely to be? And whether an adaptor exists to go from standard 5" circular ducting to it.

Thanks in advance for any help!

Try roofing vents .co.uk there will be an adapter but you will need to know what vent you have.

Cheers for that, yeah it looks like this would be close to what I'd need. I'll do some digging!

Nope that one is too small and so is this one. So it doesn't appear to be from Manthorpe or a Klober?

It's a ropey picture but the oval port is about 180mm at the widest and 100mm at the narrowest.

Anyone got any ideas?

Cheers for that, I think it is actually a Redland DuoPlain Redline like this.

I just need to find someone that sells them now I guess.
