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.

Double-layer louver HVAC diffusers have two layers of mutually perpendicular sheets to adjust the angle of horizontal and vertical blades, and adjust the airflow diffusion surface to change the range. The outer frame width of the HVAC diffusers has two kinds of wide frames and narrow frames. Double-layer louver HVAC diffusers can be used by manufacturers in ventilation systems with special requirements. The double-layer louver HVAC diffusers have two layers of movable blades with adjustable angles, and the short blades are used to adjust the diffusion angle of the supply airflow and also to change the direction of the airflow; The adjustment of long blades can make the air supply flow stick to the ceiling or incline downward at a certain angle (when supplying warm air). The outer blade of the double-layer louver vent or the blade of a single-layer louver vent can be parallel to the long side or the short side, which can be selected according to customer requirements.

Used in heating and cooling air conditioning systems, can be installed on the side wall or ceiling. The vertical louver-type air outlet has a positive-pressure air conditioning room for automatic exhaust. Normally, the louver at the air outlet will naturally sag by its own weight to isolate the indoor and outdoor air exchange. When the indoor air pressure is greater than the outdoor air pressure, the airflow will blow the louver open and exhaust outwards. Conversely, when the indoor air pressure is less than the outdoor air pressure, the airflow cannot reverse into the room, and the air outlet has a one-way check function.
