Supply Air Element Series
The ALD-SV is an outer wall air vent. Outer wall air vents are used as passive air diffusers for living rooms and bedrooms. They are mainly used in combination with the exhaust air units of the Silvento range. These extractors create a constant negative pressure that transports fresh air into the house via the outer wall air vents.
The ALD-SV is the outer wall air vent for high volume flows up to 25 m³/h with simultaneous high sound insulation. Three volume flow rates can be set by means of the reducing screen. This means that different room sizes with different air requirements can be optimally and comfortably ventilated by the ALD-SV. A staggered arrangement of multi-surface sound absorber modules has proven to be the most efficient variant.
The module is inserted into the round duct 9/R 160 (ø 160 mm). The electrical connection is not required, as the ALD-SV is a passive supply air element.
The comfort in the living rooms depends to a large extent on the positioning and condition of the outer wall air vents. Therefore, the installation position must be carefully planned. If the incoming air is heated as quickly as possible and outside the occupied zone, there is no risk of draughts. Therefore, an optimal arrangement of the outer wall air vents in relation to the heating surfaces is necessary.
Our outer wall air vents ensure user-independent ventilation in accordance with DIN 1946-6 when planned in accordance with standards.
