​An air curtain is an invisible barrier of air that separates two different environments, such as indoor and outdoor spaces. It works by using high-speed fans that blow a stream of air down across the opening to create this barrier. The force of the air creates a seal over the entrance, preventing insects, dust particles, and pollutants from entering.

air curtain is another form of local air supply. Its purpose is to create an air barrier to reduce and block the convection of indoor and outdoor air, or to change the direction of polluted air flow.

The air curtain uses strip nozzles to send out a curtain-like air flow of a certain speed, a certain temperature and a certain thickness, which is used to block another air flow.

Depending on the state of processing of the airflow transmitted, the air curtain is divided into an unheated air curtain and a hot air curtain. The air curtain is divided into two types of installation, horizontal and vertical, and the types of heat sources include hot water, steam, electricity, etc.
