Air Knife is a kind of industrial instrument that creates a consistent, high-velocity airstream using compressed air. To enable an uninterrupted flow of air, it typically consists of a narrow, flat profile that spans the breadth of a surface or conveyor. In industrial settings, air knives are frequently used to clean, dry, chill, or remove dirt from surfaces. Air knives can also be utilized as a component of a manufacturing process to control product temperature or to act as a barrier to stop contamination.
