Planning to install a bench fan ("hob with integrated fan"), which would then go down into the laundry room under the kitchen. The exhaust from the laundry room goes into the ceiling height through the adjacent room (asbestos pipe marked in orange in the photo). Would it be possible to run the fan exhaust through this pipe? This is what we currently use for the kitchen fan.
The room in the picture is a shower room where we've taken down a wall (formerly a sauna), now 12m2 shower + bath - and there we now have two exhaust pipes (both marked in red). The last one (marked in green) ventilates a separate 2m2 guest WC.
Could we perhaps make do with the square pipe (red) from the shower room and then use the round 160mm spiro from the laundry room as exhaust?
It’s sensitive to do something unwise with ventilation, especially from a basement. My next best option is to create a new duct that I lead out through the facade (by blocking a window). Hmm, I also need to keep an eye on the operable windows here. I realize I'm not very knowledgeable about ventilation, which I'm sure is noticeable
, so I'd like to hear opinions.

What does it look like around the channels?
The duct from the kitchen hood should meet fire class EI 15

In addition to the channel needing to be fireproof, there are also requirements for the outlet that can cause problems if it goes out through a wall. You need to have fireproof material around the outlet, and a good bit upwards.
Yes, you probably won't do that since it's asbestos cement, but asbestos cement is extremely fireproof. I was mostly thinking that it is practically the duct we are using now, and it was approved by the fire authorities as recently as six months ago. But maybe it only applies to new installations.H hempularen said:
