The spherical adjustable air outlet is a nozzle-type air supply diffuser designed to direct a high-velocity airflow toward a specific direction through its nozzle body. The direction of the airflow jet can be conveniently adjusted both vertically and horizontally, while the airflow volume can be regulated by adjusting the degree to which the internal valve is opened or closed.
Spherical adjustable nozzles are widely utilized in large public spaces, high-ceilinged industrial facilities, and environments where there is a significant distance between the air supply outlet and the area of human activity. They offer an air supply throw distance ranging from 5 to 30 meters. Typical applications include concert halls, theaters, museums, cinemas, airports, high-speed railway stations, and similar venues.
