An Energy-Saving Air Curtain provides a small volume of compressed air in blade form through slots along its entire length, for wide-area blow-off applications. Air Curtains (also known as Air Knives) are tools that are often employed to blow liquid (drying applications), dust, or other debris from products travelling along conveyor systems. Air Curtains are also used within recycling facilities to move lighter or smaller particles at certain steps in the process, to remove other foreign particles from products/areas, may be used in drying and also in cooling applications.
