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.

When we need to buy or change a new air terminal unit, we are facing differences in the name of the air terminal unit: air diffuser and air grille HVAC. So what’s the difference between them? Do they look the same? Okay, let’s get started now! HAVC diffuser is normally made of aluminum or plastic(pp or ABS) around the world. Some special markets prefer metal HVAC diffusers, like the US market. The function of an HVAC diffuser is to supply air and return air in buildings or houses. The HAVC diffuser’s core is removable in most models and its maximum flow area is not higher than 4 meters. The HVAC grille is normally made of aluminum or plastic(ABS) for the most market. Even US market, most of them are made of aluminum as well. Its function is mainly to return air instead of supply air. Its airflow is usually less than the air diffuser.
