In summary, the purpose of an air curtain is to improve energy efficiency, maintain environmental separation, enhance comfort, and ensure cleanliness by creating an effective barrier of air across openings.

Air curtains work by creating an invisible barrier of high-velocity air across an opening, such as a door or window. This barrier effectively separates two different environments, typically the inside and outside of a building. The air curtain is installed above or alongside the opening and consists of a fan and a nozzle or series of nozzles that direct a stream of air downward or across the opening. When the air curtain is activated, the fan draws in air from the surrounding environment and forces it through the nozzles at high speed. This creates a continuous stream of air that forms a barrier. The air stream is usually angled slightly outward to ensure that it covers the entire opening and prevents the mixing of air from the two sides. The primary function of an air curtain is to maintain the desired indoor climate by preventing the infiltration of outside air, which can carry dust, pollutants, insects, and temperature variations. In heated or air-conditioned spaces, air curtains help in reducing energy consumption by minimizing the loss of conditioned air and the entry of unconditioned air. Air curtains are commonly used in commercial and industrial settings, such as retail stores, warehouses, and food service establishments, where doors are frequently opened and closed. They are also used in cold storage facilities to maintain temperature control. In addition to energy savings, air curtains improve comfort by reducing drafts and maintaining a stable indoor environment. They also enhance hygiene by acting as a barrier against airborne contaminants and pests. Overall, air curtains are an effective solution for maintaining environmental separation while allowing easy access through open doorways.
