CONSTRUCTION FEATURES
The single slot linear diffusers with concealed perimeter frame of the DL.LM series are generally installed in confined spaces with a height between 2.7 and 4.5 m and designed for systems operating with temperature differences between room air and supply air of ± 10 K. The most frequent type of installation is flush with the ceiling, so they can fully exploit the Coanda effect. They can also be installed on the wall. In this case, if the distance between the upper edge of the diffuser and the ceiling is less than 200 mm, a Coanda effect is still achieved; otherwise, a free-field discharge is achieved. By setting opposite throw directions for each slot, the so-called “opposite throw” is achieved.
The concealed perimeter frame, designed to facilitate the laying of plaster, makes the DL.LM series popular with architects and 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 so as to follow the ideal line of the room perimeter. A deflection element that can be manually swiveled from the front is mounted inside the diffuser, allowing for a variable throw direction from horizontal to vertical.
