An air curtain, also known as an air door, is a device used to prevent air or contaminants from passing through a doorway or window opening. Air curtains are used in various settings, including office buildings, factories, hospitals, and grocery stores.
Air curtains work by creating a barrier of air that is forced downwards across the opening. The airflow prevents outside air and contaminants from entering the space while allowing people and objects to pass through.
Air curtains can be used in both indoor and outdoor settings. They are typically mounted above doorways or windows and can be operated manually or automatically.
