Downdraft extractor

[G1ABB]

Something for the technically minded.

Due to cock up by kitchen designer, I need a downdraft extractor with an external motor. I'm struggling to find one which shows the dimensions and extractor point options. Essentially the designer forgot to include the motor housing and the only answer is to use a unit with an external motor. Ducting will have to run in channel through concrete floor. I'm hoping motor housing can be at low level and not higher up our external wall and therefore more visible.

I have thrown the problem back to the kitchen company to sort out but I want to look for myself to see what the options are.

It's amazing what you learn when you start these little projects!

Any help?

My folks used to have a Gaggenau downdraft extractor which was very effective

The spec sheet for one of the current Gaggenau units seems pretty comprehensive in terms of dimensions and whatnot,and you can find it here: https://products.bsh-partner.com/picenterext/specs...

Try this website as it's quite a good motor unit!
By external motor do you mean it will be fitted outside ? if so you are probably best looking for an American manufacturer.
Lots of these need 200mm ducting so make sure this is even possible before ordering anything!
Good luck.

I have fitted one of these , I liked the Luxair ones but size wise didrnt work for me . Landed up with a De-Dietrich

I didn't need an external fan unit managed to get this hidden in a space where I might have other vine had a corner unit,, but still remote from the pop up unit . My fan unit,is,next,to the wall and exits at low level. It's all very quiet,even on full blast .

The extract quality is not as good as good over head but then it has to.drag stuff downwards. But the fan are powerful and are designed for whole room clearing , there are calcs somewhere on net for this

We love ours

Gutmann make some great units which can be used with external motors.
Kitchen company should sort it out if it's their cock up.

We have a Wolf with an external fan unit. Was a squeeze to get the extractor into the island but using 450 deep Blum drawers and runners I got it in OK - maybe rejigging drawer depths would help you in this case? Large cross section extract pipe is needed, I think it was 150 or 200 mm ld, run under the (fortunately) suspended floor. Sucks from the base of the extractor, with a rectangular to round ducting adapter.

I've seen a few where the manufacturers spec 8 inch ducting; therefore I'd say it's good advice to tell the OP to keep an eye on it. Also the yanks have a lot of high end kit we don't typically see or think about here as we think ze germans are the be all and end all - given the OP needs a product to fit a particular situation I'd say widening his net to consider yank stuff is good advice too.

For the external extract aspect: http://www.justfans.co.uk/swf-sidewall-mounted-ext...

100mm, 150mm and 200mm options. Minimise the number of bends, use spiral wound, galavanized round ducting if possible, try not to go lower than 150mm if you want reasonable extraction.

Just bought this extractor - not wired it in yet, but is chunky and heavy and looks up to the job. (150mm xl )

We've got a Caple which has a kick plate motor so it all fits in a 600 x 500m cupboard and then a 300 behind it for the extract housing. 150mm ducting if I remember correctly.

We love it, and it work's very well. I specced the wrong size motor (physically) to start with so now have an external motor sat in the corner of the garage gathering dust!

Weston's are British.

Well done OP, 150mm dia is spot on for your needs. Just make sure all pipe work is Regid. Any bends in flexi will flatten the pipe when the extractors on and badly reduce extraction.

We have one getting fitted to our kitchen this week.
Heard good reviews and was the best option for our design.

[Chippo1]

I used 200 x 90 rectangular ducting which run between the legs under the units the only flexible duct was from the fan unit and through the wall which was 150mm diameter , all as speced by the manufacturer .

Getting the unit to,fit between the backs of the units was a mission , one set of cupboards not only lost the service duct but also the original back up,tight to the rear of the draws , the old adage of measure once twicQe and and cut , was,very true for this as it took some messing about to,get the unit in the right place , they are not small . Had to adapt a few bits of the plastic trunking to fit properly and keep,the number and off direction changes to the minimum

Fan unit for,me was the easy bit , I had huge space next to,diswaher in the corner the fan unit came with extended cables for remote fitting .

Wow, thank you for all the responses, I've been busy so only just had a chance to look.

I'll start working through your responses now...

Thank you very much PH's

[Paul Drawmer]

I have some spare 150mm steel ducting left over from an extract project if anyone is interested.
1 X 3m and 1 X 2m(approx) lengths plus 1 90deg bend and some support brackets.

Deddington North oxon.
PM me if you want it.

I'm on the case with the supplier. I've had to give them a great deal of grief, along the lines of get it sorted or bring your van tomorrow and take the entire kitchen away as it is sat in my garage unused and isn't fit for purpose. Already a week since problem first identified.

Hopefully everything will get resolved today. Fingers crossed.

I've sent all the relevant details of the external motor options and await some feedback.

Meanwhile, thank you so much for all your help. Google doesn't always give the answer easily... Some of the options mentioned I've never heard of before despite searching over the weekend.

Thanks again.

PS I'm glad I don't run my business that way!
