The air curtain can inhale the air inside the room through the cross flow fan, and then blow it out in
continuous, high-speed ow downward to the oor, 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�
