Fab5Freddy Posted October 10, 2023 Share Posted October 10, 2023 I can only seem to find round pipe for venting out of the cooker hood. Am I missing a part/adaptor from here to round for this? (photo is from above and sideways ) Can anybody point me to one please? Link to comment Share on other sites More sharing options...
ProDave Posted October 10, 2023 Share Posted October 10, 2023 Yes there is a part missing, almost certainly specific to that particular hood and not available as a spare part. If you have just bought it, take it up with the supplier. If this is an existing old hood, time to get inventive and make something. Link to comment Share on other sites More sharing options...

So long as it's sealed , it'll be good enough? No real safety issues with a none standard vent? (I won't make it with plastic or cling film haha) Edited October 10, 2023 by Fab5Freddy Link to comment Share on other sites More sharing options...
ProDave Posted October 10, 2023 Share Posted October 10, 2023 Simplest form, cut a piece of say plywood to fit the rectangular hole then drill a large round hole to match the ducting. It will probably be noisier than the proper bit as that would have been some form of tapered transition. Some more inventive people here would make something on their 3d printer.

Fab5Freddy Posted October 10, 2023 Author Share Posted October 10, 2023 (edited) The thought just came to me I might be able to use a tapered dust hood from a wood working extractor - they end in round exit of roughly similar size? Then some tape on the joint Or....even better (cheaper) , a rain water/gutter hopper Edited October 10, 2023 by Fab5Freddy Link to comment Share on other sites More sharing options...
saveasteading Posted October 10, 2023 Share Posted October 10, 2023 These bixings are usually taken up to the ceiling. Then you use plastic ducts, either round or rectangular, through the wall or through the ceiling, to outside. Angles or battens fixed to the ceiling will give you something solid and rectangular to fix to. The main fan section will usually have a round spigot that takes a standard flexible duct. If not, the vented air will find its way through whatever outlet. you provide. Link to comment Share on other sites More sharing options...
Fab5Freddy Posted October 10, 2023 Author Share Posted October 10, 2023 (edited) Cheers @saveasteading I just found these adaptors from square to round. It might help get a better seal, and cheap too. Various sizes. https://www.amazon.co.uk/Kair-Offset-Straight-Rectangular-Adaptor/dp/B004X4S1K0/ref=sr_1_30?keywords=cooker%2Bhood%2Bducting%2Bkit&qid=1696958221&sr=8-30&th=1 Edited October 10, 2023 by Fab5Freddy Link to comment Share on other sites More sharing options...

ProDave Posted October 10, 2023 Share Posted October 10, 2023 What are the measurements of your rectangle? I suspect those stock rectangular to round adaptors are way too small. I like the idea of a re purposed drain hopper. Take some measurements and visit a builders merchant to see what (nearly) fits. Link to comment Share on other sites More sharing options...

Yes, I should have put that in original post. 100mm x 120mm external Link to comment Share on other sites More sharing options...
