Air Doors, also known as air curtains, are specialized devices installed above or alongside doorways to create an invisible barrier of high-velocity air. This air stream effectively separates indoor and outdoor environments while allowing unobstructed physical access. Air doors are commonly used in commercial, industrial, and retail spaces to maintain interior climate conditions, enhance energy efficiency, and improve overall air quality.

By preventing the entry of dust, insects, pollutants, and unconditioned air, air doors help maintain a comfortable and hygienic indoor environment. At the same time, they reduce the load on heating and cooling systems by minimizing temperature fluctuations, making them a cost-effective solution for energy conservation.
