The energy-saving wall box

Technically sophisticated, optically appealing, and with high-quality workmanship: The berbel wall box is the perfect termination for any exhaust duct. When the extraction system is switched on, the wall box opens automatically; it then closes automatically once the extraction system is no longer in use. This means that valuable heat is not lost from the room. For a great kitchen climate!

A robust exhaust system

When it is closed, the berbel wall box has an excellent insulation value of 0.95 W/m2K - that corresponds to triple insulation glazing or a 24 cm thick brick wall with an insulating course of at least 6 cm. In conjunction with berbel exhaust pipes and a berbel extractor hood with an EcoSwitch function, this enables energy savings of up to 50%. In addition, the air remains clean and unpleasant odours cannot spread to other rooms.

Planning information

Planning Guide
    • Installation dimension for BMK-F: 325 mm respectively
    • Installation dimension for BMK-L: 325 mm; if using a 90° bend + 100 mm; if using a transitional round pipe to a flat duct, + 250 mm
    • If using BMK-Z with a BMK-L, window contact switch 1002265 is required for connecting the devices.
    • The BMK is motor-driven and requires an external power supply - socket within 1 m or extension cable (see recommended accessories).
    • Wherever possible, only use pipes with a smooth inner surface/rigid plastic pipes. If flexible or spiral tubes are used, there will be a reduction in performance (40%) due to air flow turbulence. We recommend that any existing flexible/spiral tubes be replaced.
    • Fixation material (screws/dowels) must be purchased in accordance with the façade material.
    • The standby value of the wall box is around 0.3 watt.
    • Required core holes:
      BMK 150 mm Ø: min. 162 mm
      BMK 125 mm Ø: min. 137 mm
