ASV: Aluminum Return Air Louver

The Aluminum Return Air Louver consists of multiple large, approximately 45-degree angled slats horizontally fixed to the outer frame. The slat spacing is determined by the required effective area, providing excellent ventilation. Commonly found in wall-mounted ventilation structures, customers can optionally equip it with mesh/insect netting for even better sound insulation.
