Air Curtain


As per the scientific definition, an air curtain is a fan-powered device that creates an invisible air barrier over the doorway to separate efficiently two different environments, without limiting the access of the people or vehicles. The Air curtain was an invention that reduced heating and cooling costs by up to 80% while protecting the internal climate with energy-saving air screens. Also, It keeps the atmosphere clean from pests and insects, dust, airborne, pollution, smells, odors, and stops droughts and cold or hot air entrances.

Functioning of Air curtain:

The functioning of an air curtain is based on a high-velocity jet of air that covers all entrances. In air curtain air jets need to be placed on the top, which divides warm and cold areas into two thermal zones. So the air curtain keeps the internal environment at a comfortable warm temperature and avoids cold air penetration from outside. Effective positioning of the air curtain saves up to 80% of the energy and improves effectiveness.
