CONSTRUCTION FEATURES
The BF.DEK series linear slot diffusers with concealed perimeter frame are generally installed in enclosed environments with a height ranging from 2.7 to 4.0 meters and are designed for HVAC systems operating with a temperature difference between room air and supply air of ±10 K.
The most common installation method is flush with plasterboard, either ceiling-mounted (for vertical air throw) or wall-mounted (for horizontal air throw).
In wall-mounted applications, if the distance between the upper edge of the diffuser and the ceiling is less than 200 mm, a Coandă effect is achieved; otherwise, the air throw occurs in free space.
The concealed perimeter frame, designed to facilitate placement over plasterboard, makes the BF.DEK series popular with designers who find in it not only plant functionality but also a motif for decor. They can be used for both supply and return air, and are suitable for variable air volume (VAV) systems operating within the 50% to 100% flow range. In special execution, they can be mounted one after the other to form continuous strips that, with the use of special non-active angle pieces, are able to follow the ideal line of the room perimeter.
