    Smoke dampers

    They are designed to remove smoke and heat from a burning building, keeping escape and fire routes open. They are usually used in public places, such as staircases or connections of residential building wings, as well as in industrial and office spaces.


    Features:

    • GGL and GGU pivot window with factory-fitted KFM smoke ventilation motor
    • CE-marked, according to European standard 12101-2 for smoke and heat extraction flaps
    • The smoke ventilation window is offered in two versions: with or without a wind deflector, thus meeting the requirements for different types of applications (if a smoke ventilation active area is required, the window must be installed with a deflector)
    • For increased safety, all window versions have safety glass

    When the smoke ventilation function is activated, the window sash opens up to 90° with a chain drive


    Application

    The VELUX smoke and heat extraction system complies with the regulations on building smoke ventilation. The system consists of an electrically controlled VELUX rotating window with gas cylinders to assist opening and a factory-fitted smoke ventilation drive. Depending on requirements, the smoke ventilation window can be installed with or without a wind deflector.

    The required size of the smoke and heat extraction ventilation area depends on the design of the building and its purpose. VELUX smoke ventilation windows are available in different sizes to suit practically any solution. Like other VELUX windows, the smoke extraction system will provide to residents and other users of the building additional sunlight and fresh air. Additional advantages are: aesthetic appearance, attractive finish and long-term reliable operation.


    2 system solutions

    Smoke ventilation windows must be installed together with wind deflectors if the requirements apply to aerodynamically active surfaces.

    Smoke extraction windows without wind deflectors must be used if the requirements only apply to the geometric surface.


    The smoke extraction system consists of:

    The basic element of the system is the VELUX smoke ventilation window. The windows are available with standard NCS S 7500-N aluminium cladding and safety glass -70.
    On special request, the windows are available with copper or zinc titanium cladding, and energy-saving two-chamber glass -66.


    Note:

    In the case of installation of smoke ventilation windows in a combi set with a deflector, the distance between the windows have to be:
    - horizontal - 20 cm,
    - vertical - 25 cm.
