New Air Knife Can Cut It At Higher Temperatures.A bar-type air knife An air knife is normally used in manufacturing or as the first step in a recursive recycling process to separate lighter or smaller particles from other components for use in later or subsequent steps, post manufacturing parts drying and conveyor cleaning, part of component is newly available in stainless steel stainless steel: see steel. stainless steel Any of a family of alloy steels usually containing 10–30% chromium.
