Round Ceiling Diffuser with Multi-Layer Conical Structure for Uniform Airflow in High-Strength Aluminum and Removable Core

Product Introduction

The Round Ceiling Diffuser is a circular air supply terminal specifically designed for commercial building HVAC systems. Manufactured from high-strength aluminum sheet using spin forming technology, it delivers air in a horizontal (attached) discharge pattern that diffuses evenly in all directions. Widely used in shopping malls, offices, hotels, hospitals, and other commercial spaces, it offers wide diffusion area, uniform airflow distribution, and aesthetic appearance.

Applicable Locations

Round ceiling diffusers are widely used in commercial building HVAC supply air systems. Typical applications include:

Product Advantages

1. Multi-Layer Conical Structure – Uniform Airflow Distribution

The round ceiling diffuser features a multi-layer conical design delivering horizontal (attached) airflow. Since the induced airflow exceeds the exhaust volume, the discharged air decelerates rapidly, enabling uniform airflow distribution across any given area with variable diffusion radius as needed.

2. Aluminum Construction – Aesthetic and Durable

Manufactured using high-quality aluminum sheet spin forming technology for high structural strength and attractive appearance. Available with electrostatic coating, anodizing, or other finishes in custom colors — integrates seamlessly with various ceiling designs. Aluminum diffusers offer excellent appearance and superior diffusion characteristics.

3. Removable Core – Easy Maintenance and Adjustment

The diffuser core assembly is separable from the outer frame for easy installation, cleaning, and airflow adjustment. Inner blades can be adjusted in two positions for different seasonal conditions — horizontal airflow for summer, vertical for winter.

4. Damper Compatible – Precise Airflow Control

The diffuser neck can be fitted with a round volume control damper (OBD opposed blade damper) for convenient front-side airflow adjustment. Dampers can be configured at the diffuser rear as needed.

5. Two Airflow Patterns Available

The round diffuser can be adjusted for two airflow patterns based on room function requirements: attached airflow and vertical airflow. Install by inserting into duct and securing through mounting holes in the diffuser ring.
