The EXAIR Super Air Knife is a Highly Engineered and intelligently designed point of use compressed air powered device that delivers a 40:1 air amplification ratio! This simply means that for every one part compressed air supplied to an EXAIR Super Air Knife it will entrain 40 parts ambient air into the exiting compressed air stream. Almost as good as “money for nothing”! Also the EXAIR Super Air Knife is designed to provide an even or “laminar” flow of air. This is due to it being an intelligent, highly engineered compressed air product.
However if an EXAIR Super Air Knife is not connected to the compressed air supply with the appropriate number of inlet ports being fed, poor and/or erratic performance is likely. This would manifest itself as uneven air flow and lower performance from the air knife. In order to make this plumbing easier we offer optional plumbing kits for all Super Air Knives starting with the 24″ length all the way up to the 108″! The 24″ and longer Super Air Knive’s require that compressed air must be supplied to multiple air inlets along its length for optimal performance. This will ensure that the air flow is laminar and the force is even across the entire length of the Super Air Knife. All our products are shipped with an installation guide referencing the proper recommended pipe sizes for various lengths of supply pipe.
The Plumbing Kits for Aluminum Super Air Knives provide properly sized Nitrile/PVC Hoses, Brass Fittings and a Pressure Gauge which monitors the inlet pressure to the air knife. If the gauge shows a pressure drop when the Super Air Knife is turned on this indicates that there is an air starvation issue. For the 303SS, 316SS and PVDF Air Knives the Plumbing Kits contain 5/8 OD SS tubing X .034 wall thickness tubing and SS fittings.
So when ordering your next Super Air Knife be sure to designate the Plumbing Kit to ease your installation and to ensure top performance.
