Product applications
The centrifugal air curtain machine is a device that utilizes the high-speed air generated by centrifugal fans to create an invisible air barrier, isolating indoor and outdoor air exchange. Widely used in public places like shopping malls, factories, hospitals, and restaurants, it effectively prevents insects, dust, and temperature loss while maintaining fresh indoor air. The machine employs a high-efficiency motor to drive the impeller, generating airflow that accelerates to form the air curtain through aerodynamic principles, ensuring energy savings and efficient air exchange.
