Purpose
The air curtain is installed above the entrance of refrigerated, air-conditioned, dust-proof, and heat-insulated spaces such as theaters, hotels, restaurants, conference halls, cold storage, and homes. When activated, it separates indoor and outdoor air and dust, providing convenience for entry and exit while preventing the exchange of cold and hot air between indoors and outdoors.

At the same time, it also has the effects of preventing odors, pollution, and mosquitoes and flies. Currently, air curtains are widely used in industries such as electronics, instrumentation, food processing, footwear manufacturing, services, and commerce, creating a favorable business environment for many establishments.
