QXY PVC air knives provide a cost-effective and corrosion-resistant solution for low-pressure drying, cleaning, and liquid blow-off applications. 

They are especially suitable for acid and alkali environments, chemical processing equipment, PCB wet lines, and applications where metal materials may react with the production medium. 

With simple adjustment, flexible sizing, and reliable performance, PVC air knives are a practical choice for large-scale or budget-sensitive industrial airflow systems.
