The spherical air outlet is primarily used in environments where the distance between the air-conditioning supply outlet and the occupied zone is relatively large. In large public spaces — such as various halls and assembly rooms — where ceiling supply outlets cannot evenly distribute air or achieve the desired effect, spherical air outlets should be installed for side air supply.
When the temperature difference between the supply air and the room temperature constantly changes, the airflow will deviate upwards (hot air) or downwards (cold air). The air supply direction may also be disturbed by external factors, such as local convective airflow or lateral airflow. To address this, certain models of spherical air outlets are designed to rotate. The air supply direction can be adjusted manually on site or electrically swung within a 30° range. Customized pneumatic or electric control systems can be provided according to user requirements.
The spherical air outlet achieves ideal noise control through its optimized aerodynamic outlet structure design. Its high-quality form also makes it suitable for high-end venues such as concert halls, theaters, and museums. A variety of outlet types are available to suit different indoor conditions and technical requirements, including very high noise-reduction demands, and can be used with virtually all ventilation equipment.
Spherical nozzles are available in a wide range of models suitable for almost all application scenarios. The fixed spherical nozzle is a nozzle with installation holes. The exhaust nozzle of the adjustable spherical nozzle is spherical and is inserted between the shells, equipped with an installation decorative cover plate and a circular connector that can be plugged directly into a round pipe. The nozzle can be manually adjusted within a maximum range of 30°, or adjusted via electric or pneumatic devices.
The product provides flange rings and flange heads for axial connection, as well as ventilation pipe interfaces with peripheral flange rings. A flange ring with a flange can also be selected. To enable lateral connection with square or circular supply pipes, flat flange rings and saddle flange rings are also available.
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 |
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 are designed for long throw distances (15–25 m), making them ideal for high-ceiling spaces. Swirl diffusers have a high induction ratio and uniform diffusion, making them suitable for medium-height spaces.
Electric models come with 24V or 220V actuators. They can be connected to building automation systems (BAS) or controlled independently with manual switches.
Yes. Standard colors are silver (anodized) and white (painted). Custom colors are available upon request.
Yes. Manual types can be adjusted on site by hand. Electric types can be adjusted remotely via the control system.
