Product applications

The centrifugal air curtain machine utilizes high-speed air from centrifugal fans to create an invisible barrier, isolating indoor and outdoor air exchange. Suitable for public spaces like shopping malls, factories, hospitals, and restaurants, it effectively prevents insects, dust, and temperature loss while maintaining fresh indoor air. The device's high-efficiency motor drives the impeller, generating accelerated airflow that forms the air curtain through aerodynamic principles, ensuring energy savings and efficient air exchange.
