Product applications
Air curtain machines contribute to energy savings by reducing air conditioning loss through open doors, leading to lower energy costs and a reduced environmental footprint. Additionally, they support sustainability by minimizing the need for chemical pesticides.
Air Curtain Casing
The air curtain's casing features a sleek design that combines modern aesthetics with artistic elements. Its unique shape and smooth lines enhance the upscale atmosphere in luxurious settings like hotels and malls, functioning both as essential equipment and an elegant decorative piece. Every detail reflects meticulous craftsmanship, from precise welding to flawless polishing and perfect painting, ensuring a premium finish that signifies superior quality.
Air Curtain Motor
The air curtain's motor features ball bearings and pure copper construction, delivering enhanced efficiency and durability. Pure copper ensures excellent conductivity, efficient operation, reduced 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. The precision design enhances overall performance and reliability in various environments.
Air Curtain Impeller
Our air curtain features a fiberglass impeller, providing exceptional strength and flexibility for stable, high-speed operation under heavy loads. Its lightweight design facilitates easy installation and handling, making it ideal for environments requiring frequent reconfiguration. Fiberglass's excellent corrosion resistance ensures long-term reliability by protecting against chemicals and moisture, even in harsh conditions.
