Duct Diffuser (Supply) – Detailed Description A Duct Diffuser (Supply) is a key component in HVAC systems designed to distribute conditioned air (cooled or heated) evenly into a room from the supply ductwork. Installed typically on ceilings or high sidewalls, these diffusers ensure proper airflow direction, speed control, and uniform air distribution, enhancing comfort and energy efficiency. Made from durable materials like aluminum or steel, supply diffusers come in various designs such as square, round, or linear patterns. They often feature adjustable blades or louvers to regulate airflow direction and volume. High-quality diffusers reduce noise levels, prevent air drafts, and blend aesthetically with interior designs. Supply diffusers are essential in both residential and commercial buildings, helping maintain optimal indoor climate while complementing the system’s performance and appearance.
