General questions about BORA
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.
BORA Professional cooktops are characterised by an extra-depth of 540 mm and a width of 370 mm, which allows for more cooking space. They are controlled via stainless-steel knobs with touch operation on the front cover. Thanks to a large number of different cooktops and ventilation components, BORA Professional systems can be constructed in a modular way, they are highly variable and can therefore be planned individually.
BORA Classic cooktops have a standard depth of 515 mm and are controlled via touch operation . Thanks to a large number of different cooktops, BORA Classic systems are highly variable and can therefore be planned easily and individually. Click here to view all BORA Classic products
BORA Basic is a compact unit with a size of 515 x 760 mm or 515 x 830 mm in the case of BORA Basic with surface induction (BFI), comprising a large cooktop with four cooking zones and a centrally positioned extractor. BORA Basic is also controlled using an intuitive touch operation up front in the middle of the cooktop. The new BORA Basic BFI has an innovative, new operating concept of a touch-operated round slider.
BORA Pure is immediately recognisable by its central, round and slightly recessed air inlet nozzle as well as its flush design. Thanks to the central control and optimum layout of the cooking zones, BORA Pure offers a lot of cooking space. The system is operated by simply sliding the vertical sControl touch slider up and down or by clicking the plus/minus control directly. BORA Pure is a compact unit consisting of a powerful induction cooktop with various functions and an efficient cooktop extractor. Two products under one product number. This means that the kitchen planner has to initiate and check only one ordering process.
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 Basic and BORA Pure models, larger volumes of up to 3 litres of liquid can be caught. The housing base can be removed for simple cleaning.
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.
The grease filter and covers can be removed easily by hand and cleaned in the dishwasher.
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 depends to a large extent on the individual installation and space.
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 his or her clothes and hair remain fresh and unaffected by cooking vapour.
Cooking vapour is easily absorbed even from a pan with a height of 20 cm. We recommend that for pans with a height of approx. 21 cm and over, you position the pan lid diagonally to conduct the vapours in the direction of the extractor.

Questions about humidity
Relative humidity gives the saturation level of the air at the current temperature. Warm air can take up more water, cold air can take up less water. I.e. cold air is saturated more quickly. For a comfortable heat, the relative humidity lies between 25 and 60% at a room temperature of 20 to 25 degrees Celsius.

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%.
Watch the video "How humidity develops during cooking” here.
In compliance with current building standards and the German Energy Saving Ordinance (EnEV and DIN 4108), mould formation is excluded when using BORA air circulation or exhaust systems in old and new buildings, and in a normal indoor climate. Wood and kitchen components, as well as other components, are not damaged.
In general: Observe the general instructions in BORA’s assembly documentation for air circulation and exhaust operation!
Questions about the exhaust solution
In the case of BORA Professional and BORA Classic, it is possible to implement exhaust ducting of up to 16 metres using various fan modules and the BORA Ecotube duct system. For individual planning, you can always contact your professional BORA partner.
In the case of BORA Basic with surface induction BFIA, exhaust ducting stretching 10 metres is possible when using the additional duct fan ULIE.
For BORA Basic BIA and BHA and BORA Pure, the exhaust channel should not exceed the maximum length of 6 metres.
Yes, each of the cooktop extractors needs separate exhaust ducting with separate wall sleeves or, optionally, its own recirculation unit.
Questions about air circulation
Yes, all BORA cooktop extraction systems can be planned both as air circulation and as exhaust air variants.
The recirculation unit ULB1/UUE1 has to be replaced annually; the recirculation unit ULB3/UUE3 every two years. The integrated filter in the BORA Basic (BAKFS) and the BORA Pure cooktop extractor system (PUAKF) should also be replaced annually or after 150 operating hours. The integrated filter indicator notifies you when this period has passed. Click here to access mybora Shop, where you can order your replacement filters.
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.
To guarantee optimal performance from the odour-neutralising activated charcoal filter, we always recommend the automatic cut-off. This takes 20 minutes and adjusts itself automatically as soon as the ventilation is turned off. Basically, you should ensure that there is sufficient ventilation (e.g. an open window) when cooking in recirculation mode.
Questions about cooktops
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 Basic cooktops are available as Hyper, induction and surface induction models. BORA Pure is purely an induction cooktop. Here you will find more information on our product ranges.
BORA cooktop extractors are only available in combination with BORA cooktops.
The cooktops are precisely tailored to the measurements of the cooktop extractor and therefore enable optimal installation.
All BORA product lines can be installed flush and surface-mounted. For Classic, there is also the option of installing the standard combination with 2 cooktops and 1 cooktop extractor virtually flush on worktops made of any kind of material, including laminate, with the help of the BORA Classic CER frame.
No, the product lines cannot be combined with each other.
The BORA brushed stainless steel cooktop frame is an accessory for surface mounting. It is available in two sizes: BKR830 with a width of 830 mm for BORA Basic BFIA/BFIU and BKR760 for the 760 mm wide BORA Basic BHA/BHU/BIA/BIU cooktops and for BORA Pure.
The black air inlet nozzle is available as an accessory for all new Basic models.
However, this combination is not recommended for BHA/BHU and BIA/BIU Basic cooktops that have already been installed due to to the fact that the fit will not be exact or joints will appear.
The standard delivery includes the black PUED air inlet nozzle. The colour versions rose gold (PUEDG), blue (PUEDB), jade green (PUEDG), red (PUEDR), orange (PUEDO) can be ordered separately as accessories.
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 depends on the position and 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 Basic BFIA/BFIU, the floor unit must have a width of 900 mm. With BORA Basic BIA/BIU/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 Basic and BORA Classic.
The installation depth of BORA Professional varies according to the type of installation. A minimum depth of 650 must be given (plus worktop overhang, if present).
For all three BORA cooktop extractor systems, we need a worktop with a thickness of between 10 and 40 mm, including base. The basic needs to be notched accordingly for thicker worktops.
