Product of the Year Award Winner- Long Super Air Knives

20150327_134253

Plant Engineering’s 2014 Product of the Year Award!

 

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.

72″ Long Super Air Knife – One Piece Air Knives available in lengths up to 108″

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.

Long Super Air Knife Dries Cast Acrylic Sheets

5967985755_91dd48ce36_b

I have a customer who works for a company that produces plain, acrylic sheets which are used to produce various products used in high end bathrooms. Generally, those products are bathtubs, shower surrounds, floor pans, etc.

Our customer produces the flat sheet which is produced by pouring a liquid resin between two glass sheets which is then cured to a solid phase. Once the glass molding material has been stripped away, the edges are finished and the sheet is washed and dried.

The drying part is where EXAIR 84” Long Super Air Knife comes into play. The customer’s sheet is two meters wide and so the 84” Super Air Knife provides a continuous curtain of air across the surface of the acrylic sheet to drive the rinse water off the sides and edges. Once dried, our customer lays a protective sheet of heavy paper between the sheets of acrylic to keep the surfaces from being scratched or otherwise blemished from rubbing during transport.

Prior to moving to the Super Air Knife for this production, the customer was using a series of 40 pieces of a flat, plastic, two inch wide, air nozzle made by a company who specializes in water nozzles. The nozzles themselves were designed to consume 24 SCFM @ 80 PSIG each. The customer had these mounted to a 1” pipe that was hung above the acrylic sheet. The problem was that these nozzles used so much air that they could barely keep 30 PSIG on the header pipe supplying them due to pressure drop in their system and the noise level was up over 90 dB. The result, poor blow off performance. The estimate for their air usage was in the range of 450 SCFM for this project.

After installing the 84” Super Air Knife, the customer was able to finally maintain a reasonable header pressure of 80 PSIG at the inlets to the Super Air Knife which provided for a solid and consistent blowing velocity all the way across the width of the material. The sound level was also able to drop down to a more pleasing 75 dB with implementation of the Super Air Knife. Finally, the air consumption was dropped to a more reasonable 244 SCFM for the 84 inch Super Air Knife. A 46% reduction on air usage.

If you have a wide format type of product that you are trying to cool, dry or blow debris from, consider the Long Super Air Knives. They will provide you with a forceful, even velocity across the full width of your material.

New Products To Serve New Applications Available In EXAIR Catalog 27

John of Partech CorporationJohn Son of Partech Corporation, South Korea

Last week I had the pleasure of meeting with the EXAIR distributors for South Korea (Partech Corporation) and Japan (CS Tech).  While there, we spent a great deal of time discussing applications for various EXAIR products, especially those which are new to our product lines. EXAIR’s NEW catalog 27 is now available and contains all of the details regarding our new product additions!

With the addition of Long One Piece Super Air Knives, the High Lift Reversible Drum Vac, and new Atomizing Nozzles we had “lengthy” discussions about the possibilities of the new products and the new application problems which can be solved.

For example, in a blow off application with critical need for a long length of fully laminar and continuous blowoff, the long, one piece Super Air Knife can provide a viable solution.  Or, when liquid needs to be vacuumed from a vessel that is 4 meters (13.2 feet) deep, the High Lift Reversible Drum Vac can be used.  And, for an enclosure coating application, the new Internal Mix Deflected Flat Fan Atomizing Nozzle can provide an atomized liquid spray at a right angle to the nozzle orientation, spraying the internal sides of the enclosure.

These new products, and all others, can be found in EXAIR’s catalog #27.  Click here to request your copy today.
