| High Light | 30 meters throw distance Ball Jet Diffuser ，±30° directional adjustment HVAC Diffuser ，High-strength aluminum Air Supply Terminal | ||
The Ball Jet Diffuser is a long-distance air supply terminal specifically designed for commercial large-space HVAC systems. Manufactured from high-strength aluminum, the spherical nozzle provides ±30° directional adjustment with a maximum throw distance of 30 meters. When conventional ceiling diffusers cannot deliver air evenly in large halls or high-ceiling spaces, ball jet diffusers are the ideal solution. Widely used in airport terminals, theaters, sports venues, exhibition centers, commercial atriums, and other high-ceiling spaces.
Ball jet diffusers are widely used in commercial buildings requiring long-distance air supply in large/high spaces. Typical applications include:
| Facility Type | Specific Application | Key Reason |
|---|---|---|
| Airport Terminals | Departure/arrival hall air supply | Very high ceilings requiring long throw |
| Theaters/Concert Halls | Auditorium air supply | Low noise requirement, aerodynamic design |
| Sports Venues | Spectator area, arena air supply | Large area, long-distance delivery |
| Exhibition Centers | Exhibition hall, conference room supply | High-ceiling spaces with long throw requirements |
| Commercial Atriums/Lobbies | Shopping malls, hotel lobbies | Combines function with aesthetic appeal |
| Industrial Facilities/Assembly Halls | Large workshop ventilation | Eliminates air supply dead zones |
| High-speed Rail/Bus Stations | Waiting hall air conditioning | High-occupancy spaces require uniform airflow |
1. Ultra-Long Throw Distance – Covers Large Spaces
Engineered with aerodynamically optimized structure, ball jet diffusers achieve a throw distance of up to 30 meters. When supply air temperature differs from room temperature, the airflow automatically adjusts its trajectory — horizontal for cooling, downward for heating — enabling efficient air mixing. Compared to conventional diffusers (3-8m throw), ball jet diffusers significantly reduce the number of terminal devices required.
2. ±30° Directional Adjustment – Adapts to Seasonal Changes
The spherical nozzle can be manually or electrically adjusted within ±30°. Horizontal delivery in summer allows cool air to naturally drop; downward tilt in winter delivers warm air directly to the occupied zone. Thermal control models feature built-in temperature sensors that automatically adjust the nozzle angle based on supply air temperature — no manual intervention or power required, offering energy-saving and maintenance-free operation.
3. Low Noise Operation – Suitable for High-Requirement Spaces
Ball jet diffusers employ optimal aerodynamic design to control noise while delivering high airflow and long throw. Measured data shows noise levels as low as 20dB(A) at 20m throw distance, making them ideal for theaters, concert halls, hospital waiting areas, and other noise-sensitive environments.
4. Aluminum Construction – Aesthetic and Durable
Manufactured from high-strength aluminum with powder-coated finish (standard RAL9010/9016) and custom color options. Equipped with aluminum decorative rings, the sleek modern design complements various interior styles while providing corrosion resistance for long-term use.
5. Flexible Installation – Electric Option Available
Supports both direct circular duct connection and side-wall mounting on square ducts. The spherical nozzle fits securely in the housing with a circular connector for quick installation. Electric actuator options enable remote centralized control for building automation integration.
6. Wide Size Range Available
Available in diameters from 100mm to 630mm for flexible selection based on space height and airflow requirements. All sizes support customization to meet diverse project specifications.
