ALD-R 160 filtered fresh air device with sound reduction

Lunos ALD-R 160 - Fresh air device

More Details


The new ALD-R 160 with weather protection grille, for new or existing buildings

Since its development in 2002, the ALD-R 160 has become one of the top selling air transfer devices in the LUNOS range. Its versatility has been demonstrated by the wide spectrum of applications for which it has been used. It is used in combination with the 9/MRD installation block in new buildings, for example, 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 façade element.

Compatibility

The objective when re-developing the ALD-R 160 was to achieve higher versatility and greater noise protection. The ALDs available from LUNOS up to now, in their various design forms and flow rates, are to be replaced by an ALD which 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 façade element.

New vibration control units

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.

One for all – One air transfer device for all applications

In working towards improving the level of comfort, attention was paid to ensuring even greater flexibility and a wider scope of possible applications. In the past, LUNOS 3 included a range of different air transfer devices for different applications and also for different volumetric flow rates. The new, optimised ALD-R 160 is now equipped for use in all types of application. 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-R 160 provides optimum ventilation and comfort in various sizes of room and with various air exchange requirements.
