product applications

The uses of air curtains include: separating different areas of airflow, maintaining indoor temperature stability, preventing external dust, insects, and pollutants from entering, reducing the exchange of hot and cold air, improving energy efficiency, enhancing air quality, and increasing comfort. They are widely used in supermarkets, shopping malls, hospitals, cold storage facilities, train stations, airports, restaurants, factories, and recreational environments.

product casing

Our air curtain features a curved design and metal coating. The curved casing not only offers a sleek and attractive appearance but also reduces sharp edges, lowering the risk of accidental injuries and enhancing safety. Its ergonomic design ensures comfortable operation and maintenance. The metal coating improves the casing's corrosion resistance, extends its lifespan, and provides various color and texture options, meeting personalized needs while enhancing both aesthetics and functionality.

product motor

The air curtain features a pure copper motor and ball bearings. The pure copper motor offers excellent conductivity and efficient operation, reducing energy consumption. Its superior heat dissipation ensures stable performance over extended periods, minimizing the risk of failures. Copper also enhances the motor’s durability and reliability. Ball bearings significantly reduce friction, allowing the air curtain to operate more smoothly and quietly. Their high load capacity ensures stability during high-speed operation, extending the equipment's lifespan. Additionally, the precision of the ball bearings improves the overall performance and reliability of the air curtain.

product impeller

Our air curtain features a fiberglass impeller with multiple advantages. Firstly, fiberglass offers excellent strength and flexibility, allowing it to withstand the stresses of high-speed operation and ensure stable performance. Secondly, its lightweight nature reduces the overall weight of the air curtain, making installation and movement easier. Additionally, fiberglass is resistant to corrosion and wear, extending the impeller's lifespan. Furthermore, its superior insulation properties effectively prevent electrical leakage, ensuring safe operation.
