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.
Casing
The air curtain's casing features elegant, unique shapes and flowing lines, enhancing luxury venues like hotels and malls. Each component is meticulously crafted, from precise welding to flawless polishing and painting, ensuring a premium finish that reflects superior quality.
Motor
The air curtain's motor features ball bearings and pure copper for enhanced efficiency and durability. Pure copper ensures excellent conductivity, efficient operation, lower energy consumption, superior heat dissipation, and minimized overheating risks. Ball bearings reduce friction for smoother, quieter operation, support high-speed stability, and extend the motor's lifespan. Precision design boosts overall performance and reliability in diverse environments.
Impeller
Our air curtain boasts a fiberglass impeller, delivering outstanding strength and flexibility for stable, high-speed operation under heavy loads. Its lightweight design eases installation and handling, perfect for environments needing frequent reconfiguration. Fiberglass's excellent corrosion resistance guarantees long-term reliability by shielding against chemicals and moisture, even in harsh conditions.
