Scale for discharge angle Throw distance 60 %, with swirl unit and cap Acoustically and technically optimised The new TJN jet nozzle offers improved acoustic properties and is also more energy efficient. Up to 6 dB less noise than with DUK jet nozzles due to optimised nozzle contours Discharge angle indication, limiting and setting (±30°) using a concealed scale Visible parts made of high-grade polymer in RAL white aluminium or pure white Easy to remove face cover ring with bayonet fixing Throw distance 80 %, with swirl unit 5 nominal sizes, each with a circular spigot or, as an option, with a connection piece for circular or rectangular ducts Optional equipment and accessories Swirl unit for two-step reduction of the throw distance due to air control blades with unique saw tooth edges Compact height actuator that requires little additional space; mounted externally hence not affecting the differential pressure Actuator allows for integration into the central BMS All variants also with outer casing
