Product applications
The centrifugal air curtain machine harnesses the power of high-speed air produced by its centrifugal fans to establish an invisible barrier, effectively minimizing indoor-outdoor air exchange. Ideal for public spaces such as shopping malls, factories, hospitals, and restaurants, this device prevents insects, dust, and temperature fluctuations while maintaining fresh indoor air. The system employs a high-efficiency motor and aerodynamic principles to generate energy-efficient airflow.
