An air curtain (sometimes called an “air door”) is a device used to separate two spaces from each other using a controlled flow of air to restrict the combination of the two environments. The most common configuration of an air curtain is a downward-facing blower fan (with or without a heating element), blowing air across the area of the opening.

About Air Curtains
Air curtains are most often mounted at an exterior entrance to a building, but can also be used effectively between two spaces conditioned at different temperatures (between a refrigerated area and an ambient temperature area, for example). They are often utilized in grocery stores and retail shops with exterior entrances. Other common applications include drive through windows, cargo doors, airplane hangars, and shipping/receiving doors. Air curtains are most often used to keep heat in and cold out, or vice versa. They can also be employed to keep insects out by creating forceful air turbulence. This turbulence can also be used to keep dust and other environmental contaminants from entering a work area. Air curtains are an effective way to reduce energy costs. They reduce the load on a building’s heating and/or air conditioning system, and these energy savings are generally substantial enough to pay for the cost of purchasing and installing the air curtain in just a year or two. Many air curtains also utilize a door switch or other mechanism which turns the unit on or off as the door opens and closes, eliminating unneeded usage and further boosting energy savings. Air curtains typically operate in high face velocities in industrial settings. In commercial applications, lower face velocities are generally preferred for customer comfort.
