Can you vent the kitchen fan through a fitting like this?

[MTech]

Hello Hello!

I am going to fix the ventilation for the sewage and kitchen fan now as there is a vacuum valve for the sewage and the kitchen fan blows through a hole in the roof sheathing right onto the tiles, meaning there is no penetration in the tiles...

My question to you is if it is possible to use something like this also for the kitchen fan?

It's significantly cheaper than this one:

The roof tile itself should work, but the flexible hose underneath that is tailored for sewage might become a fire hazard if you connect it to the kitchen fan?

What do you think?
I would save a considerable amount, but I don't want to be penny wise and pound foolish, so I'm checking with you now!
During inspection, the current solution was flagged precisely for the fire risk, they built houses strangely in the 70s:x

But it will rain into the fan, in the ventilation that doesn't matter.

Ha ha yes of course, I didn't think of that But there must be some simpler version than the hood I linked to above? I think 2 thousand+ is a bit expensive but well

I'm using this: http://www.luftbutiken.se/takhuvar/1349-takhuv-abc-vhs-160-svart-avlufts-uteluftshuv.html
(also available for just over 1000 in 125mm design)

It should be approved as an imkanal and I'm satisfied with both the fit and quality so far.
