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.

What is a damper? The damper is also known as a volume-directing damper. It is a movable plate fit to the air vent diffuser and grilles to control airflow volume and direction or installed in the ductwork to cut or regulate airflow to specific areas. Dampers are often used in ventilation ducts to create different airflow zones in a building. A good quality damper also helps in maintaining the desired level of humidity and temperature throughout the area. Discover additional details on chinaventech.com.
