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.

• Long throw distance (15–25 meters)
• 360° adjustable air direction
• Gentle airflow with low noise
• Aesthetic appearance and flexible installation

Ball jet diffusers are widely used in large-space commercial buildings. Typical applications include:

• Throw distance up to 15–25 meters (30 m 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 or slightly upward — Winter: downward angle

• Nozzle design induces surrounding air
• Velocity gradually decays — soft and comfortable at the occupied zone
• No cold draft sensation — even temperature distribution

• Optimized airflow path
• Operating noise ≤ 45 dB(A)
• Suitable for quiet environments such as malls and hotels

• Modern, clean spherical design
• Custom colors available to match interior decor
• Aluminum alloy construction for a premium quality feel

• Circular duct suspension, square duct side-mount, or independent bracket
• Adapts to different building structures

Ball jet diffusers operate on the jet induction principle:

1. Conditioned air is projected from the nozzle at high velocity.
2. The high-velocity jet induces surrounding stationary air.
3. Induced airflow can reach 3–5 times the primary air volume.
4. Velocity gradually decays — soft and comfortable at the destination.

• Throw distance should cover the occupied zone.
• Nozzle spacing is typically 1.5–2 times the throw distance.
• Electric type is recommended for BAS integration.
• CFD simulation is recommended for large projects.
