An air curtain uses a blower or fan to force a directional stream of air in a downward direction. The forced air creates an invisible barrier that helps to control temperatures by preventing hot or cold air from entering a doowrway or building at an opening. Air curtains also are used to keep contaminants such as insects, dust, pollen, and other debris, from entering an interior space.
