The supply air diffuser has the function to take air from the outside environment and let it pass through it,then enter the indoor atmosphere. This process not only helps in enhancing HVAC performance but reduces energy wastage as well. With a damper, the air diffuser can control the volume of air flowing into a room or area you have chosen and helps in controlling the direction of airflow. When air coming directly from the air ducts sometimes causes noise. The air diffuser also can reduce noise as air comes out of the vents in a minimum amount in different directions which makes the noise process less.
