Ball Jet Diffuser | Long Throw Air Supply Solution for Commercial Large Spaces

Product Specification

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.

1. Product Overview

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

2. 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.

3. Core Advantages

3.1 Ultra-Long Throw Distance

• 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

3.2 Flexible Air Direction

• Spherical design supports 360° manual adjustment

• Electric actuator option for BAS remote control

• Summer: horizontal/slightly upward — Winter: downward angle

3.3 Comfortable, Gentle Airflow

• Nozzle design induces surrounding air

• Velocity gradually decays — soft and comfortable at occupied zone

• No cold draft sensation — even temperature distribution

3.4 Low Noise Operation

• Optimized airflow path

• Operating noise ≤ 45dB(A)

• Suitable for quiet environments like malls and hotels

3.5 Aesthetic Appearance

• Modern, clean spherical design

• Custom colors available to match interior décor

• Aluminum alloy — premium quality feel

3.6 Flexible Installation

• Circular duct suspension, square duct side-mount, independent bracket

• Adapts to different building structures

5. Working Principle

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 destination

9. 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.
