Coast to Coast and Beyond

Recently, I was working with  a customer looking for a Premium Reversible Drum Vac and wanted it shipped to the Northwest Territories of Canada –  which we could do!  It got me to thinking, what are the farthest US state and territory locations EXAIR has shipped to in the North, South, West and East directions.  I ‘scoured’ the records and came up with these.

Furthest North- We have shipped to Prudhoe Bay, Alaska.  Most recently, believe it or not, we shipped a NEMA 4X Cabinet Cooler to an Oil and Natural Gas Exploration Company.  Goes to show that even the coldest environments still have the need to provide cool, clean, dry air to cool and protect electronics in electrical enclosures.

Furthest South – We have shipped to the US Territory of Puerto Rico, city of Santa Isabel.  An Aerospace company needed a strong, laminar blast of air and utilized a 6″ Stainless Steel Air Knife.  An Air Knife offers a quiet, efficient way to clean, dry or cool parts, webs, or conveyors.

Furthest West- We have shipped to the US Territory of Guam.  The local University ordered a model 1111-4 Super Air Nozzle Cluster, for a good strong blast of air flow for a cleaning operation.  The model 1111-4 delivers 3.2 lbs of force, at just 82 dBA of sound. A safe and efficient nozzle for blowoff operations.

Furthest East- We have shipped to Eastport, Maine.  The customer in Eastport ordered a Line Vac and a section of Conveyance Hose.  The Line Vac is a great tool for conveying large volumes of material over long distances, through a standard hose or tube.  The compact design features large throat diameters for maximum throughput capability.

 

It was interesting to look back and see all the places that EXAIR has shipped.  We have customers from all over the globe. If you are outside the of 50 US States and Canada, we have a dedicated team of International Application Engineers that will work with you to select the best EXAIR product for your process and application, and direct you to your local International Distributor.

If you 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.

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.

Super Air Knife – Free Air Via a 40:1 Amplification Ratio

Intelligent Use of Compressed Air – Most industrial facilities have at least one air compressor.  The compressor is used to power anything from pneumatic tools, air powered equipment, compressed air cylinders, blowoffs and many more types of operations.  Improper use of compressed air can lead to unnecessary energy costs, high noise levels and dangerous exposure of personnel to high pressure air.

The EXAIR Super Air Knife uses only 1/3 of the compressed air of typical blowoffs.

By taking advantage of the Super Air Knife’s highly efficient design and the action of air entertainment, the Super Air Knife draws in large amounts of surrounding free outside air into the air stream. The result is a strong powerful air flow made up of a small amount of compressed air and a large amount of ambient air.

Capture

  • Compressed air flows through an inlet (1) into the plenum chamber of the Super Air Knife. The flow is directed to a precise slotted orifice. As the primary airflow exits the thin slotted nozzle (2), it follows a flat surface that directs the airflow in a perfectly straight line.  This creates a uniform sheet of air across the entire length of the Super Air Knife. Velocity loss is minimized and force is maximized as room air (3) is entrained into the primary air stream at a ratio of 40:1.  The result is a well defined sheet of laminar airflow with hard-hitting force and minimal wind shear is delivered.

By using a Super Air Knife – and the advantage of the high amplification via air entertainment – for part blowoff, cooling, or drying you can reduce energy costs, reduce noise levels, and eliminate harmful dead end pressures. Other air knives typically entrain surrounding air at a ratio of 30:1 or less.

EXAIR offers the Super Air Knife with materials of construction of aluminum, Types 303 and 316 Stainless Steel, and PVDF to cover a wide variety of application temperatures and environments. Other materials may be possible, pending review by our Product Design Engineers. The Super Air Knives are offered as the knife only, as part of a full kit, which also includes a shim set, auto drain filter separator, and pressure regulator.  The Super Air Knife can be fitted with Plumbing Kits and/or Electronic Flow Control making installation easier and help to save on air usage.

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.

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.
