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 rooms, and residential 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.

Additionally, it offers benefits such as odor prevention, pollution control, and protection against mosquitoes and flies. Currently, air curtains are widely used in industries including electronics, instrumentation, food processing, footwear manufacturing, services, and commerce, creating a favorable business environment for many enterprises.
