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.
Casing
The casing of the air curtain boasts a sleek and elegant design with unique shapes and flowing lines, making it a perfect fit for luxury venues like hotels and malls. Every detail reflects meticulous craftsmanship, from precise welding to flawless polishing and painting, ensuring a premium finish that signifies superior quality.
Motor
The air curtain's motor features ball bearings and pure copper construction for enhanced efficiency and durability. Pure copper provides excellent conductivity, efficient operation, lower energy consumption, superior heat dissipation, and reduced overheating risks. Ball bearings minimize friction for smoother, quieter operation, support high-speed stability, and extend the motor's lifespan. A precision design ensures optimal performance and reliability in diverse environments.
Impeller
Our air curtain incorporates a fiberglass impeller renowned for its exceptional strength and flexibility, ensuring stable, high-speed operation even under heavy loads. Its lightweight design makes installation and handling easy, ideal for environments requiring frequent reconfiguration. Fiberglass’s superior corrosion resistance offers long-term reliability by protecting against chemicals and moisture, even in harsh conditions.
