Product Overview
The spherical air outlet is mainly used in environments
where the distance between the air supply outlet of the air
conditioner and the area where people are active is relatively
large. When public places (such as various halls and assembly
rooms, etc.) have a large area and the ceiling air supply outlet
cannot evenly distribute the air or achieve the desired effect, in
such cases, spherical air outlets should be installed for side air
supply. When the temperature difference between the air supply and
the room temperature constantly changes, the air flow will deviate
upwards (hot air) or downwards (cold air). The air supply direction
may also be interfered with by external factors, such as local
convective air flow or lateral air flow. Therefore, some models of
spherical air outlets can be designed to rotate. The direction of
air supply can be adjusted manually on the spot or electrically
swing within a 30° range. Customized pneumatic or electric control
systems can be provided according to user needs. The spherical air
outlet achieves ideal noise control due to its optimal aerodynamic
air outlet structure design. Also, its high-quality shape design
makes it suitable for high-end places such as concert halls,
theaters, and museums. Various types of air outlets are provided,
suitable for various indoor conditions and technical requirements,
and can meet very high noise requirements. It can be used in all
possible ventilation equipment.
Construction and Dimensions:
There are various models of spherical nozzles, 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 that can be directly plugged into the round pipe.
The nozzle can be manually adjusted within a maximum range of 30°,
or it can be adjusted through electric or pneumatic devices. The
product provides flange rings and flange heads for axial
connection. The product also provides ventilation pipe interfaces
with peripheral flange rings. A flange ring with a flange can also
be selected. To be able to connect laterally with square or
circular supply pipes, the product also provides flat flange rings
and saddle flange rings for selection.
Applicable Locations
Ball jet diffusers are widely used in large space commercial buildings. Typical applications include:
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.

FAQ
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.
