NTDL-D: Anti-Drop™ Drum Louvers

Anti-Drop™ Drum Louvers are characterized by their robust construction that delivers long-distance airflow. They consist of extruded aluminum blades within a rotating drum, which control the direction of airflow and reduce noise. They are commonly found in airports, high-speed rail stations, and large air outlets.
