Embedded Circular Diffuser – Minimalist Hidden Supply & Return Air Terminal
To meet the demands of high-end residential fresh air systems, QIYUE proudly launches the embedded Circular Supply & Return Diffuser. As a new-generation indoor air terminal, it achieves dual breakthroughs in decorative aesthetics and ventilation comfort.Manufactured by one-step injection molding with virgin ABS material, the diffuser features a rigid, deformation-resistant structure. It effectively resists ageing and yellowing even after long-term installation within ceiling cavities. The unique 360° peripheral air outlet disperses airflow, eliminating uncomfortable direct draughts caused by conventional vents. It is widely adopted in new residences, luxury villa fit-outs and commercial office ventilation projects.Equipped with a perforated embedded flange for pre-installation during ceiling construction, only the central adjustable disc is exposed upon project completion, delivering a seamless minimalist ceiling appearance. Fitted with orange spring clips, the unit allows tool-free assembly and disassembly. A removable insect and dust filter is built inside, and airflow can be precisely regulated via the central adjusting screw.It saves significant installation time and facilitates easy maintenance. Ideally compatible with balanced ventilation and HRV heat recovery systems, this product can function as both supply air terminal and return air terminal.
🔹 Gentle peripheral airflow, no uncomfortable direct draughts:The central guide disc distributes air evenly around the perimeter for mild airflow. Unlike standard diffusers with concentrated direct airflow, cold or warm air will not blow directly on occupants to greatly boost living comfort. Ideal for long-term continuous ventilation in living rooms, bedrooms and studies.
🔹 Concealed embedded design, perfect for high-end minimalist interior finishes：Comes with a perforated embedded base to be pre-installed within plaster ceilings during construction. The whole flange stays hidden, leaving only the central disc exposed after renovation. Boasting a plain elegant finish, it fits seamlessly with modern, light luxury and other mainstream home styles. Compatible with plasterboard ceilings, balancing decorative appearance and ventilation performance.
🔹 Spring clips for tool-free assembly & disassembly, cutting construction and maintenance costs：Adopts spring clip fixing structure, installed in a similar way to downlights. One person can complete installation quickly. The unit can be detached manually for filter cleaning and maintenance, saving on-site labour and simplifying long-term upkeep.
🔹Built-in filter protects ventilation ductwork：A removable filter cartridge inside blocks insects, hair, dust and debris from entering ducts. It prevents duct blockages from accumulated dirt, reduces deep duct cleaning frequency and extends the service life of ventilation units and heat recovery cores.
🔹 Continuously adjustable airflow for various room conditions：Rotating the central adjusting screw changes the air passage size to achieve stepless airflow regulation. Ventilation volume can be adjusted separately according to room size and application, balancing the fresh air efficiency of the whole property.
