| High Light | 4-Way Uniform Air Supply Square Ceiling Diffuser ，High-Strength Aluminum Air Grille ，Removable Core Design Ventilation Louver | ||
Product Introduction
The Square Ceiling Diffuser is a 4-way uniform air supply terminal specifically designed for commercial building HVAC systems. Manufactured from high-strength aluminum profiles, it delivers air in a horizontal (attached) discharge pattern that diffuses in all directions. Widely used in office buildings, hotels, shopping malls, hospitals, and other commercial spaces, it ensures comfortable, even airflow distribution while providing an aesthetically pleasing appearance — making it one of the most commonly used air terminal devices in commercial projects.
Applicable Locations
Square ceiling diffusers are widely used in commercial buildings with ceiling heights under 5 meters. Typical applications include:
| Facility Type | Specific Application | Recommended Configuration |
|---|---|---|
| Office Buildings | Standard floor air supply | 4-way diffuser + OBD damper |
| Hotels | Guest rooms, corridors, lobbies | Narrow frame + Coated finish |
| Shopping Malls | Public areas, retail stores | 4-way diffusion, aesthetic design |
| Hospitals/Clinics | Waiting areas, patient rooms | Low noise + Removable core |
| Schools/Libraries | Classrooms, reading rooms | Cost-effective configuration |
| Theaters/Concert Halls | Auditorium air supply | Low noise, high comfort |
Product Advantages
1. 4-Way Uniform Airflow — Draft-Free Comfort
Square ceiling diffusers deliver air in a horizontal (attached) discharge pattern that diffuses in all directions. Available with 1 to 4 airflow directions. The 4-way pattern ensures even coverage across the space below, rapidly equalizing temperature, reducing air velocity, and effectively preventing discomfort from direct drafts.
2. Aluminum Construction — Aesthetic and Durable
Manufactured from high-strength aluminum profiles with anodized finish for excellent corrosion resistance. Available with electrostatic powder coating or baking paint finish in custom colors — integrates seamlessly with various ceiling designs.
3. Removable Core Design — Easy Installation and Maintenance
The frame and inner core are separable for easy installation and adjustment. For maintenance, simply remove the core without dismantling the entire frame — significantly reducing service time and effort.
4. Damper Compatible — Precise Airflow Control
Can be paired with air volume control dampers (Herringbone/OBD opposed blade damper) at the rear. Multiple configurations available with wide-range airflow adjustment to meet different zone requirements.
5. Low Noise Operation — Quiet and Comfortable
Square diffusers feature excellent induction performance, rapid and even diffusion, and low noise characteristics. Particularly suitable for noise-sensitive spaces such as hospital patient rooms, hotel guest rooms, and libraries.
