The special-shaped louver vent is a kind of air distributor. In air conditioning engineering, various types of air supply outlets and return outlets (or exhaust outlets) are generally referred to as air distributors. Common louver HVAC diffusers include single-layer louver HVAC diffusers, double-layer louver HVAC diffusers, side wall grille HVAC diffusers, and slot grille HVAC diffusers. Single-layer louver HVAC diffusers are often used for return HVAC diffusers, sometimes with an aluminum alloy mesh filter or nylon filter screen. The double-layer louver HVAC diffusers are composed of double-layer blades. The front layer of the blades is adjustable, and the back layer of the blades is fixed. The opposite multi-blade air volume regulating valve can be configured as required to regulate the air volume of the HVAC diffusers.

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.

The damper is easy to move to control airflow. For a damper with manual control, there’s one handle you just move the handle to control the blade open and close. About the one with mechanical control, there’s a screw control part, you just use the screwdriver to move the screw will be ok. The damper is an essential part of the air diffuser and grille and HVAC system. They are used to regulate the temperature in your building while providing efficient heating and cooling. Without these dampers, the air is not evenly distributed, making your building’s temperature inconsistent. This can make the heat and cool the area not getting proper airflow. So they are very important for the duct works. Read more information at https://www.chinaventech.com/.
