In the first quarter of 2025, we received an instruction from the consultant to resolve the issue where the original aluminum round diffusers could not effectively deliver airflow to the podium. After conducting on‑site airflow data analysis and calculations, we proposed two cost‑effective improvement options. The client ultimately selected the higher‑cost option that provided better performance: replacing the original round diffusers with our Anti-Drop coated nozzle‑type jet diffusers (Model: NTJN), and installing a reducer adapter behind each diffuser.

The jet nozzle diffuser offers a longer throw distance, and its anti‑drop coating prevents condensation water droplets from falling. Post‑completion video footage shows that the plants on the podium were visibly swaying due to the airflow, confirming that the air delivery performance was achieved, and the client accepted the work with satisfaction.
