Product applications
The centrifugal air curtain machine is a powerful air isolation solution, ideal for commercial buildings, factories, and warehouses. By accelerating air through a high-speed rotating centrifugal impeller, it creates an effective air barrier that minimizes indoor-outdoor air exchange. This maintains stable indoor temperatures, prevents dust and insects from entering, and enhances both environmental comfort and energy efficiency.
