Ball Jet Nozzle Diffuser

1. Overview of Ball Jet Nozzle (Spherical Jet Diffuser)

1.1

Ball jet nozzle is general‑purpose HVAC supply air terminal, specially designed for large high‑ceiling spaces such as airports, railway stations, gymnasiums and workshops. Wall‑mount or duct‑mounted for long‑distance jet air supply. Inner spherical nozzle can deflect within ±30°. It tilts upward for cold air supply in summer and tilts downward for hot air supply in winter, solving insufficient throw distance of conventional grilles for high spaces. Optimized aerodynamic structure delivers long air throw with low noise. Mainly round shape, nominal size DN100‑DN630. Main material is aluminum alloy; ABS and stainless‑steel are optionalMade-in-Ch…。

‑ Manual Ball Jet Nozzle: Spherical nozzle angle adjusted manually on‑site during commissioning, widely used for large‑space projects. ‑ Motorized Ball Jet Nozzle: Equipped with DC24V electric actuator, adjusts nozzle angle remotely by 2‑10V signal, compatible with building management system. ‑ Thermo‑self‑actuated Ball Jet Nozzle: Built‑in thermal actuator automatically adjusts jet angle according to supply‑air temperature, no external power supply required.

1.2 Product Classification

‑ By structural shape: Round type. ‑ By adjustment mode: Manual‑adjust type, Motorized‑adjust type, Thermal self‑actuated type.

2. Operating Conditions for Ball Jet Nozzle

Operating temperature: ‑20 ℃ ~ +80 ℃ Relative humidity: less than 90% Medium condition: Conditioned HVAC supply air; stainless‑steel version for mildly corrosive environment.

Power supply: No power for manual & thermal‑actuated models; DC24V for motorized version.

4. Manufacturing Process of Ball Jet Nozzle

4.1

Aluminum version is precision‑machined and riveted from aluminum profiles. ABS version is integrally injection‑molded. Wear‑resistant rotating bearing fitted between spherical nozzle and housing for smooth deflection. Motorized type features reliable connection between actuator and nozzle shaft. Surface finishes include electrostatic powder‑coating and anodizing with custom colors available。

4.2

Rear neck is assembled with outer housing with flat flange for convenient round‑duct connection.
