Last week, Plant Engineering presented EXAIR’s Long Super Air Knives the Bronze award for Product of the Year in the compressed air category. In 2014, EXAIR introduced one piece, seamless Long Super Air Knives up to 108″ in length. No other company in the world can provide a one piece compressed air operated air knife over 54″ long. This one piece design allows for minimal footprint for long units, and an unparalleled uniform sheet of laminar air flow. These long Super Air Knives conserve compressed air over drilled pipes or a manifold of air nozzles. Their compact design excels at large web drying and cleaning operations i.e. paper, rolled steel, aluminum foils, or plastic sheets. Air knives also excel at cooling extrusions, molds, heated rollers, or components. The air knives entrain ambient air at 40:1 ratio (40 parts ambient to 1 part compressed air) which means it moves a tremendous volume of air and delivers it to your target. The Super Air Knives provide all of these benefits quietly and efficiently. The air knife creates only 69 dBA of noise at 80 PSIG of pressure and it would be a great addition in areas where anyone is trying to limit harmful noise exposure to personnel.
These air knives continue EXAIR’s history of pushing the envelope in air knife technology. In 2010, EXAIR introduced the first polyvinylidene fluoride (PVDF) air knife to the market. The PVDF Super Air Knives provide resistance to UV light, inorganic chemicals, solvents, ozone, weather, fungi, chlorinated hydrocarbons, highly corrosive acids, weak bases and salts while maintaining a quiet operation (69 dBA). This material change opened EXAIR to a variety of environments that cannot be served by blowers, aluminum, or stainless steel air knives.
