Product of the month October: our ALD
The ALD is an outer wall air vent which enables draught-free, diffuse air inflow due to its wind pressure protection and flow-optimised screen and is therefore particularly suitable for living, working and sleeping areas. Our ALDs even achieve up to 75 dB standard sound level difference and can be used perfectly with our Silvento series exhaust air units.
Depending on the requirements, the ALD can be selected with high sound values and, due to the integrated volume flow screen, also in all volume flow ranges. The accessories are also freely selectable and can thus be precisely adapted to the customer's requirements.
Our ALD-SV can be installed for volume flows up to 25 m³/h for increased sound insulation. This is particularly characterised by excellent sound insulation at the highest possible volume flow rate, which can be adjusted by means of a reduction cover.
The ALD-S is a specialist for maximum sound insulation, because sound insulation values can be achieved that were not previously possible. It contains a new flexible material that achieves a high specific weight while maintaining high flexibility.
