Air curtain is an electrical appliance usually used to separate two different temperature environments. When a temperature controlled room is frequently accessed by opening the door a significant amount of cold or hot air is lost. This usually spikes up the overall consumption of electricity used for cooling or heating the interior of a room or building. It is usually mounted over top of the door, which produces a high velocity air stream blowing from top to bottom, which acts as a barrier preventing the air escaping from inside or outside.
