| High Light | Ball jet diffuser for commercial spaces ，Long throw air supply diffuser ，Large space HVAC ball diffuser | ||
The Ball Jet Diffuser is a long-distance air supply terminal device specifically engineered for commercial large-space HVAC systems. Its spherical design enables 360° manual or electric adjustment, delivering air up to 25 meters away. Ideal for mall atriums, airport terminals, exhibition centers, sports venues, and industrial buildings, it effectively solves the common problem of traditional grilles having insufficient throw distance to reach occupied zones.
The Ball Jet Diffuser consists of a spherical housing, an inner nozzle, and an adjustment mechanism. The aerodynamically optimized interior projects air at high velocity, inducing surrounding air to move along with it — creating an "air column" that delivers conditioned air to distant areas.
Ball jet diffusers are widely used in large-space commercial buildings. Typical applications include:
| Facility Type | Specific Application |
|---|---|
| Shopping malls / retail | Atriums, high-ceiling areas, anchor stores |
| Airport terminals | Departure halls, arrival halls |
| Exhibition centers / convention centers | Exhibition halls, main conference rooms |
| Sports venues | Spectator areas, athlete zones |
| Hotel lobbies | High-ceiling atriums, ballrooms |
| Industrial buildings | High-bay workshops, warehouses |
| Transportation hubs | Train stations, high-speed rail waiting halls |
| Cultural venues | Theaters, concert halls, museums |
Core Value: In high-ceiling spaces, traditional grilles have a throw distance of only 3–8 meters — cool air cannot reach the occupied zone. Ball jet diffusers deliver air directly to target areas 15–25 meters away, enabling precise air supply and significantly improving comfort and energy efficiency.

Ball jet diffusers operate on the jet induction principle:
| Season | Nozzle Angle | Effect |
|---|---|---|
| Summer | Horizontal or slightly upward (0°–15°) | Cool air naturally drops — "air cushion" effect |
| Winter | Downward angle (15°–30°) | Warm air reaches occupied zone directly |
| Installation Method | Application | Features |
|---|---|---|
| Circular duct suspension | Spaces with suspended ceilings | Direct connection to circular duct — clean appearance |
| Rectangular duct side-mount | No ceiling or wall mounting | Round-to-rectangular adapter — saves space |
| Independent bracket | No ductwork available | Separate bracket — flexible positioning |
| Electric remote control | BAS integration needed | Electric actuator — remote control capable |
| Ceiling Height | Recommended Nozzle Diameter | Recommended Throw | Spacing |
