Super Air Knives – A Plethora of Materials and Sizes

EXAIR manufactures the line of air knives known as the Super Air Knife. We pride ourselves on the wide array of material types and lengths that we offer, all from stock.

The Super Air Knife is the latest generation of engineered air knife that dramatically reduces compressed air usage and noise when compared to other blowoffs.  It is a very efficient way to clean, dry, or cool parts, webs, or conveyors.  It delivers a sheet of laminar air flow across the entire length, with a smooth and consistent delivery of air.

In order meet process environments that may be hot or corrosive in nature, EXAIR offers the Super Air Knife in four standard materials.  The materials for stock air knives are aluminum, Type 303 stainless steel, Type 316 stainless steel, and PVDF (Polyvinylidene Fluoride.) Aluminum is well suited for a wide variety of environments where corrosion or contamination is not a factor. Type 303 stainless steel is a very common grade of stainless steel, and is good for mildly corrosive environments up to 400 °F. Type 316 stainless steel offers excellent corrosion resistance, better strength properties, and resists pitting. It can handle temperatures up to 800°F.  Lastly, the PVDF air knives offer many benefits including resistance to UV light, inorganic chemicals, solvents, ozone, acids, weak bases and salts and can withstand temperatures up to 275°F.  If there is a certain material required, EXAIR can also do custom Super Air Knives and have done them in PVC and other plastics.  Check out this write up about a very unique custom material Super Air Knife that we made.

Not only is there a wide offering of materials of construction to meet the process needs, the Super Air Knives are available in many lengths to fit into the space available. From stock, we offer Super Air Knives in these lengths-

3″, 6″, 9″, 12″, 18″, 24″, 30″, 36″, 42″, 48″, 54″, 60″, 72″, 84″, 96″, and 108″

If a special length knife is needed, or one longer than the 108″, the Super Air Knives can be coupled utilizing the stocked Air Knife Coupling Kit to join multiple air knives as needed. If space is an issue, and certain length that is not stocked is needed, just give us a call –  we can manufacture them to your specifications, to the exact length that you need.  It takes just a few days and then the Super Air Knife of exactly the proper length will be on its way.

If you have questions about the Super Air Knives, or would like to talk about any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.
