Exair air knife kits are used to enhance the working mechanism of air knives for cleaning, drying, cooling or blowoff applications. These kits include a super air knife, shim set, filter separator and a pressure regulator. The super air knives are used for delivering a quiet, hard hitting curtain of air across the entire length for maximum efficiency. Shim set allows increase / decrease in the force & volume of both consumed air & output airflow. Filter separators are ideal for separating water, dirt and scale from compressed air & keeping output clean while pressure regulators (w/ coupler) adjust the pressure required at the point of use and relieve undue pressures on fittings, hoses and tools. All models are CE compliant and are available in overall widths ranging between 3 and 54 inches.
