Product Description

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.
