Air Curtain is a device designed to be mounted above or on the side of the door covering the full entrance width. Curtains provide an invisible air barrier that separates the internal and external environment and stops cooled air escaping in a summertime or heated in a winter. Using Air Curtains is the most convenient and comfortable way of separating different temperature zones without interrupting people traffic.
Air curtains produce fast-moving airflow that blocks air movement through the building entrance. By stopping the air movement, curtains reduce heat loss, seal the building from the environment and saves an energy. It is very important to fit the width of a device and a doorway as incorrectly installed barriers may produce a too weak air stream to stop air movement.
