A clean room with a compact design must be used because its height is limited by the height of civil engineering. Aluminum alloy air supply outlet characteristics of some local purification equipment The aluminum alloy air supply outlet has an adherent (horizontal) airflow, and its structure is a multi-layer cone. As the indoor-induced air flow is greater than the exhaust air volume, the blowing air flow decelerates rapidly. Therefore, relatively large air volume can be supplied for any size area and the size of the diffusion radius changes within the given air volume range.

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.

In HVAC a grille is a vent cover through which air is blown into or out of a room for circulation back to the central heating or cooling unit. It is mounted in duct, wall, roof, floor, and ceiling to direct the flow in the air conditioning system. The air grille can be single-deflection and double-deflection type, which single-deflection grilles providing vertical airflow direction control. Meanwhile, double deflection grilles allow both vertical and horizontal airflow direction control. See additional info on chinaventech.com.
