Extractor fan into this opening?

[pilsbury]

Welcome to my world of spending ages thinking, planning, doing, then realising down the line that things don’t line up. This keeps us mentally agile. Real problem solvers. Would be so boring if things went as they should.

What I would do (which looks like the option mentioned) is get a hood minus fan, fit one of those turbo 140mm in line fans to your ducting and then lay square/rectangular section ducting on top of your wall cupboards to outside. Looks like the fan may fit in the chimney opening between the beam. Ducting up the chimney is asking for gunk to roll back down.

Made my own from a cupboard, 200mm duct fan, commercial grease filter and some metal parts. Much more flexible and better than anything buyable

Bet that sucks like a...... something that sucks hard.

Over a million litres a hour on full, sounds like an aeroplane! But of course I used a massive fan to make it quiet at normal air flow, not to move a lot of air.

Top bodging!! I like that

That's a gratuitous slur on my wood working skill!

Sorry John, my phone must have auto corrected 'engineering' to 'bodging'.

I've just bought a 90cm telescopic Elica Elite for £20, it should come Friday so I'll see how it fits together and if I can use it.

It came today. I've pulled off the bit I need so can now get bodging.

Only thought so far is the electrics, the plug onto the fan also controls the lights. The fan could possibly sit in the web of the RSJ, it's not huge and I could put a round to square 90bend on the top.

They say necessity is the mother of all invention. Look forward to seeing your engineering masterpiece.

Don't forget your fire protection to the steel. Normally need a layer of pink plasterboard or equivalent.

Surely a decent fan as per John D's design fixed within a wall unit to the left, ducted either side, with a hood of your choosing is the best solution? Assume no problem penetrating the LH face of the chimney breast.

Just my 2c

Beers!"

 

[Ian H]

No problem with penetration

I'm off work next week so will try and get this done.
