General questions about cooktop extractor systems

Steam and vapours rise at a maximum speed of one metre per second. The BORA cooktop extracts with cross flow suction that is higher than the speed at which cooking vapours rise. In this way, the cooking vapours and odours are effectively extracted on the cooktop.

At BORA you can choose between the modular extractor systems BORA Professional and BORA Classic, and the compact systems BORA X Pure, BORA Pure, BORA Basic and BORA GP4 (only available from nobilia retailers). Our product finder will help you and your BORA retailer will be happy to advise you so that you can find the system that best suits your cooking style and design requirements.
The modular extractor systems give you optimum design freedom and flexibility when choosing your cooktops (induction, surface induction, Hyper and HiLight glass ceramic, gas, Tepan, wok). BORA Professional boasts extra-deep cooktops and operation via a control knob (like in professional kitchens). All functions are easily, conveniently and intuitively activated by turning the knob and tapping the central touch-operated surface. BORA Classic is operated on the cooktop itself using the intuitive sControl+ touch controls. The compact systems also combine a cooktop with four cooking zones and an effective extractor: BORA X Pure: surface induction; BORA Pure: induction; BORA Basic: Hyper. The compact appliances have intuitive touch controls on the cooktop. With standard dimensions and the combined design, they can be installed quickly and easily.

Depending on the system, up to 300 ml of liquid can collect in the cooktop extractor and be washed away without issue. If more liquid than this gets into the cooktop extractor, this cannot damage the electronics as the air flow does not pass through the electronics.

With BORA X Pure, BORA Pure and BORA Basic models, larger volumes of up to 3 litres of liquid can be caught. The housing base can be removed for simple cleaning.

You can find a video about it here.

Objects that fall into the cooktop extractor land in the collection dish and can be removed easily. The stainless steel grease filter prevents objects from being drawn into the airflow.

All parts that come into contact with cooking vapours can be easily removed through the wide and easily accessible air inlet opening. These removable parts, such as the grease filter, grease filter tray and air inlet nozzle/cover flap, can be cleaned in the dishwasher, where they take up very little space. Then, in a few simple steps, you can wipe away any remaining cooking residues from the extractor opening using a cloth. In these videos we show you how to clean the cooktop extractor and the Tepan stainless steel grill

In contrast to traditional extractor hoods with a high noise level at head height, BORA is quieter when cooking than normal noises that occur during roasting. The volume level largely depends on the BORA system used, the individual installation situation and the room conditions.

Cooking vapour, evaporated grease and the odours that go with them are completely extracted where they arise – directly on the cooktop. The cook stands in fresh air, while their clothes and hair remain unaffected by cooking vapours. Find out more in the video.

Cooking vapour is easily absorbed even from a pot with a height of 20 cm. We recommend that for pots with a height of approx. 21 cm and over, you position the pot lid diagonally to conduct the vapours in the direction of the extractor.

Our BORA systems can be planned individually. For price information and an individual offer please contact a BORA partner in your area.

No, you only need to register one of the cooktop extractors. The warranty then covers the whole system (cooktop extractor/cooktops through to the pipes and wall sleeve. For further details, please see the warranty conditions).

Yes – in the case of BORA Classic and BORA Basic, the air inlet nozzle simply needs to be replaced to do this. In the case of BORA Professional, both the control knobs and the cover flap and cover frame must be replaced. To do this, please contact your local BORA retail partner.

The plastic parts that you can see on the cooktop, such as the air inlet nozzle and grease filter, can be cleaned in the dishwasher at temperatures up to 65 degrees. However, they may melt if exposed to hotter temperatures, so do not place hot pots and pans on the air inlet nozzle, for example.

During normal cooking, say cooking for approx. 30 minutes e.g. vegetables, fish or meat, the increase in relative humidity in the exhaust air is barely measurable. If water is boiled vigorously for 30 minutes, the relative humidity increases by approx. 10%. You can find a suitable video here.

Questions about the exhaust solution

As a general rule, a 6-metre exhaust air channel with up to 6 bends in the duct is possible. In the case of our compact systems BORA X Pure, BORA Pure, BORA Basic and BORA GP4, the exhaust air channel should be no longer than 6 metres. In the case of the BORA Professional and BORA Classic, an exhaust air channel of up to 16 metres is possible with the use of additional BORA fan modules.  These specifications only apply where our own BORA Ecotube piping is used. A BORA retail partner near you will be happy to help you with your individual planning needs. 

Yes, each of the cooktop extractors needs separate exhaust ducting with separate wall sleeves or, optionally, its own recirculation unit.

Ecotube is BORA’s own customised exhaust air duct system, which is easy to install and perfectly designed for BORA cooktop extractor systems to ensure optimum air flow with a 100% functional guarantee.

Questions about air circulation

Yes, all BORA cooktop extraction systems can be planned both as air circulation and as exhaust air variants. You can find more information here.

The recirculation filter unit ULBF must be replaced every 1.5 years (300 operating hours), recirculation unit UUE1 once a year and recirculation unit ULB3X every three years or every 600 operating hours. The integrated filter (PUAKF) on the BORA X Pure and BORA Pure cooktop extractor systems and on the BORA Basic (BAKFS) and BORA GP4 (BAKFS) should also be replaced on a yearly basis or every 150 operating hours. The integrated filter indicator "F" notifies you when this period has passed. This link will take you to mybora shop, where you can easily order your replacement filter. You can find more information on changing the filter here.

The recirculation unit ULBF is the follow-up model for ULB1 with Ecotube connection. For all Naber duct connections, ULBF is supplied with an adapter.

The purified air is fed into the plinth area from where it is released back into the room through a return flow aperture measuring at least 500 cm² per recirculation unit. Gas cooktops require a return flow aperture measuring at least 1000 cm² per recirculation unit.

In a normal indoor climate and with proper installation, there is no risk of condensation or mould. With regard to this, please take note of the operating instructions. You can find a suitable video here.

The automatic after-run function is activated when the extractor is switched off and runs for approx. 10–20 minutes on the lowest setting (a 20-minute after-run period is preset). This dries the airways and filter units and thus guarantees that the cooking vapours will be extracted seamlessly. Once the automatic after-run period has lapsed, the cooktop extractor switches itself off.

The filter change depends on the chosen recirculation model from the BORA product line and the recirculation filter used. In the videos you will find instructions on how to change the filter and reset the filter service display. Please bear in mind that the filter service display is linked to the filter change. For more information and details, please refer to the operating instructions. You can find them in digital format here. See information on changing the filter here.

Questions about cooktops and accessories

Yes, a large range of modular cooktops is available from the BORA Professional and BORA Classic product series. Here you can choose between induction cooktops and HiLight or Hyper cooktops – the classic models with radiant heating elements. The gas cooktop and Tepan stainless steel grill complete the assortments. BORA Pure and BORA GP4 are induction cooktops, BORA X Pure is a surface induction cooktop. BORA Basic is available in Hyper. You can find further information on our product range here.

Our BORA hob extractors are specially matched to our BORA hobs. Therefore, they are only available in combination. Only in this way can we guarantee the optimum effectiveness and functionality of our BORA hob extractor systems. There is a wide range of BORA hobs, which can also be combined within some product series.

In the case of BORA Classic, X Pure, Pure and Basic, this is not possible. In the case of BORA Professional, the cooktops can be ordered and operated independently from the cooktop extractor.

All BORA cooktop extractors and cooktops can be installed flush or surface-mounted. In the case of the BORA Classic, it is also possible to install the standard combination virtually flush in worktops made of any material with the help of the BORA Classic inlay frame CER. In the case of our compact systems BORA X Pure, BORA Pure and BORA Basic, a cooktop frame or modern trim are available (also in All Black), which we recommend in order to protect the glass ceramic when surface mounted. The trim can be retrofitted in just a few simple steps. Access the MyBORA Shop here. 

No, the product lines cannot be combined with each other.

The BORA brushed stainless steel cooktop frame is an accessory for surface mounting. They are available in two sizes: BKR830 for BORA X Pure with a width of 830 mm, and BKR760 for the 760 mm wide BORA Basic cooktops BHA/BHU, for BORA Pure and BORA GP4.

The trim, made from 100% stainless steel, provides protection for the sides of all BORA cooktops with a depth of 515 mm. The trim can be retrofitted in the case of surface-mounted systems. The All Black model comes with our tried-and-tested diamond-like carbon coating.

The standard delivery includes the black PUED air inlet nozzle. The colour versions greige (PUEDG), blue (PUEDB), jade green (PUEDJ), red (PUEDR), orange (PUEDO) can be ordered separately as accessories in our online shop.

No, despite having the same outer diameter of 173 mm, the removal technology (tilt mechanism) prevents the X Pure air inlet nozzle from being inserted flush into the BORA Pure. The same applies vice versa, i.e. the colourful Pure air inlet nozzles do not fit the X Pure.

Questions about planning and assembly

Yes, but you may need to shorten the depth of the drawers, depending on the installation.

Basically, this is not recommended, as the BORA system will not be accessible to service engineers when the appliance needs to be serviced. In addition, the cooktops could overheat.

This varies depending on the selected product, the position and the number of cooktops and cooktop extractors. With a standard arrangement involving two cooktops and one cooktop extractor, you need a floor unit with a width of at least 900 mm for the BORA Professional and BORA Classic ranges. With three cooktops and two cooktop extractors, a width of 1,400 mm is required. This can be created by installing a single front cover across multiple floor units arranged in any format. With BORA X Pure, the floor unit must have a width of 900 mm. With BORA Basic BHA/BHU and BORA Pure, the floor unit must have a width of 800 mm.

From the front edge of the front cover, a depth of at least 600 mm must be available (plus worktop overhang, if present) for the installation of BORA Classic, BORA X Pure, BORA Pure and BORA Basic. The installation depth of BORA Professional varies according to the type of installation. We recommend a minimum depth of 700 mm. (plus worktop overhang, if present).

For all four BORA cooktop extractor systems, we need a worktop with a thickness of between 10 and 40 mm, including base. The base needs to be notched accordingly for thicker worktops.
