Air Curtains An air curtain is an invisible wall of air. Air curtains are installed at entrances and exits. The air blows vertically downwards. It has a specific direction and is suitable for areas where it is inconvenient to install a fence gate, as well as areas that require frequent access. It can effectively differentiate between internal and external environments. The air curtain prevents internal air from flowing out and into the interior, with an obstruction rate of 70-90%. Air curtains help prevent dust, exhaust fumes, odors and insects from entering the room.
