The Ball Jet Diffuser is a long-distance air supply terminal device specifically designed for commercial large space HVAC systems. Featuring a spherical design that allows 360° manual or electric adjustment, it can deliver air up to 25 meters away. Ideal for mall atriums, airport terminals, exhibition centers, sports venues, and industrial buildings, it effectively solves the 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.
Core Advantages:
Long throw distance (15-25 meters)
360° adjustable air direction
Gentle airflow, low noise
Aesthetic appearance, flexible installation
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.
Throw distance up to 15-25 meters (30m for large sizes)
Covers occupied zones in high-ceiling spaces
Solves the "hot ceiling, stuffy floor" problem
Spherical design supports 360° manual adjustment
Electric actuator option for BAS remote control
Summer: horizontal/slightly upward — Winter: downward angle
Nozzle design induces surrounding air
Velocity gradually decays — soft and comfortable at occupied zone
No cold draft sensation — even temperature distribution
Optimized airflow path
Operating noise ≤ 45dB(A)
Suitable for quiet environments like malls and hotels
Modern, clean spherical design
Custom colors available to match interior décor
Aluminum alloy — premium quality feel
Circular duct suspension, square duct side-mount, independent bracket
Adapts to different building structures

Ball jet diffusers operate on the jet induction principle:
Conditioned air is projected from the nozzle at high velocity
The high-velocity jet induces surrounding stationary air
Induced airflow can reach 3-5 times the primary air volume
Velocity gradually decays — soft and comfortable at destination
Seasonal Air Supply Strategy:
| 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 |
|---|---|---|---|
| 5-8m | 100-160mm | 8-12m | 4-6m |
| 8-12m | 160-200mm | 12-18m | 6-8m |
| 12-18m | 200-250mm | 18-25m | 8-10m |
| 18-25m | 250-315mm | 25-30m | 10-12m |
Selection Tips:
✅ Throw distance should cover occupied zone
✅ Nozzle spacing typically 1.5-2 times throw distance
✅ Electric type recommended for BAS integration
✅ CFD simulation recommended for large projects

Q1: What is the difference between a ball jet diffuser and a swirl diffuser?
A: Ball jet diffusers are designed for long throw distance (15-25m), ideal for high-ceiling spaces. Swirl diffusers have high induction ratio and uniform diffusion, suitable for medium-height spaces.
Q2: How is the electric type controlled?
A: Electric models come with 24V or 220V actuators. They can be connected to building automation systems (BAS) or controlled independently with manual switches.
Q3: Can colors be customized?
A: Yes. Standard colors are silver (anodized) and white (painted). Custom colors are available upon request.
Q4: Can the direction be adjusted after installation?
A: Yes. Manual types can be adjusted on site by hand. Electric types can be adjusted remotely via the control system.
