5 Piping Diagram
The air curtain can inhale the air inside the room through the cross flow fan, and then blow it out in 
continuous, high-speed flow downward to the floor, which will form an invisible “wall”. It typically is installed at 
the door or above the window. When the door or the window is opened, it can effectively separate the inside 
and outsider air. Thus, it can as much as possible reduce the loss of the cool air and prevent the dust and insect 
coming in.
