For new or existing buildings, with weather protection grille
The ALD (formerly called ALD-R 160) outer wall air vents serve as passive inflows for living rooms and bedrooms.
It is mainly used in combination with LUNOS Silvento series exhaust air units and in combination with the 9/MRD installation block in new buildings, as well as in many types of restoration projects where a core hole is drilled through the wall. It can also be combined with the LUNOtherm facade element.f
By means of its reduction screen, three airflow levels can be set: 15, 20 and 25 m3/h. The ALD is thus able to provide ideal and comfortable ventilation of various room sizes with different air requirements.
Higher versatility and greater noise protection. Thanks to various design forms and flow rates, it is also compatible with the new e2 and AB 30/60 fans. The basis for these various fans is the 160 circular tube which also enables combination with the LUNOtherm facade element.
In order to improve vibration control even further, experiments were carried out with various forms of vibration control system. A staggered arrangement of polyhedral vibration-control modules proved to be the most efficient option. Using these vibration control units, Dn,W values of 50 and 55 dB were achieved with wall thicknesses of 36 and 50 cm.
In working towards improving the level of comfort, attention was paid to ensuring even greater flexibility and a wider scope of possible applications. The Lunos ALDs is now equipped for all fields of applications. A new flow-reduction cover allows the volumetric flow rate to be adjusted to 15, 20 or 25 m3/h. This means that the ALD provides ideal ventilation and comfort in various sizes of room and with various air exchange requirements.
