ᐅ Which downdraft vent system would you recommend for a new kitchen? Any suggestions?

Looks like our Bora, and what you describe about the functionality sounds the same.

We have a downdraft extractor from Gaggenau. In my opinion, it is very slim and barely noticeable between the two cooktops. The control panel in the middle is for the downdraft unit above it. It works well and delivers good performance. Regarding boiling over: the exhaust air is drawn off sideways inside the duct, not from below. There is only one removable tray down there, so if something boils over, it flows into the removable tray, which fits in the dishwasher (removal takes about 15–30 seconds). The two hours of installation time mentioned earlier probably refers to the installation of the complete system.

Please show a bit more of your kitchen. Even just the cutout looks amazing.

I still have a few questions. We are planning to install a cooktop with a ventilation system (ducted exhaust). As a precaution, a 200mm (8 inch) spiral duct (including insulation) was installed a few days ago. I have read that most systems use a 150mm (6 inch) connection, but I hope the 200mm diameter will help reduce noise. Since the cooktop is located on an island, the duct will have three bends with a total length of about 5m (16.5 ft).

As you can tell from the questions below, I have only looked into this topic at a basic level so far.

Should I install just one damper at the end (house wall)? Should there also be a fan installed there? Does the cooktop provide a signal that can be passed on to an external fan? Do you have a function that checks whether a window is tilted open? An extraction rate of up to 700 cubic meters per hour is quite high.

Hello Sichtbeton82,
take a look at the exhaust wall vent box.
Usually, an additional indicator is needed because of the window.
I also know of solutions where there is additional draft.

@sichtbeton82 ... who recommended spiral-seam ducting? For kitchen extractor hoods, it’s best to use smooth ducting. And of course, an external wall vent should be installed. Additionally, fresh air intake should be planned during the construction phase.

We have the Berbel Downline cooktop operating in recirculation mode, and it works very well!
