The ALD-S serves as a passive supply air element for living and sleeping rooms. In combination with the LUNOS exhaust air units, such as Silvento ec, a constant negative pressure is created by the base load operation in the bathroom and/or kitchen, which ensures that fresh air is transported into the house via the ALD-S - completely without disturbing noise from outside.
New flexible material
The new flexible material made of granules is a composition of technical foams which, due to the manufacturing process, achieve a high specific weight while maintaining high flexibility. As a result, sound insulation values can be achieved that were previously not possible in this way.
The insert is inserted into the wall-tube 9/R 160 (ø 160 mm). The electrical connection is not necessary because the ALD-S is a passive supply air element.
Please follow the installation instructions and have the ALD-S installed professionally.
