Custom Products for Custom Applications

Here at EXAIR we pride ourselves on the number of problem solving products we have on the shelf that can ship same day if ordered by 3 PM Eastern Time. But some times a stock product doesn’t quite fit the bill for every application.

Since EXAIR manufactures our products at one location in Cincinnati, Ohio, this gives us the flexibility to do many things like making custom configurations with our Line Vac Systems.  Here is one example of a custom Line Vac and how the customer is using it!

The photo above shows two custom 1″ Aluminum Line Vacs with custom threaded outlets. This customer wanted to use the line vac to remove fumes from a welding application and wanted to attach one of their flame retardant filter bags to the outlet of the Line Vac! These custom threads allowed them to screw the filter bag directly onto the line vac with the added insurance of a threaded connection to prevent sparks from escaping the bag.  

No matter what your application is EXAIR is capable to work with you to create custom solutions for your application. Whether you need a different material, size or dimensions or design, EXAIR is able to meet your requirements. These Line Vacs represent only one of our many product lines that can be custom made to your specifications.

Custom Air Amplifiers: Customization to Fit Your Needs

EXAIR’s line of Air amplifiers can be found in thousands of applications across the world from everything as simple as blowing parts off to exhausting fumes. The Air Amplifier comes in two different styles either the Super Air Amplifier or the Adjustable Air Amplifier. Super Air Amplifiers come in a stock Aluminum Body with a diameter that ranges from ¾” to 8”. This differs from the Adjustable Air Amplifier which comes in either type 303 Stainless Steel or Aluminum and are Sized from ¾” to 4”.

Super Air Amplifiers are supplied with a .003″ (0.08mm) slotted air gap which is ideal for most applications. Flow and force can be increased by replacing the shim with a thicker .006″ (0.15mm) or .009″ (0.23mm) shim. Model 120028 is supplied with a .009″ (0.23mm) air gap. A .015″ (0.39mm) shim is available for Model 120028.

Even though there is a wide variety of sizes and materials for the Stock Air Amplifiers they don’t always match a customer’s specific need or application. Over the years EXAIR has produced a slew of different custom Air Amplifiers for a customer’s specific need and the following are just a few of what we have done.

  • Depending on the environment certain specific materials may be required like the food industry which requires specific Stainless Steel for various applications. One customer had a special PTFE plug made for the Adjustable Air Amplifier to help pull a sticky material through the process. The PTFE helped prevent the material from depositing on the inside diameter of the Amplifier.
  • For applications where mounting may be an issue, special attachments have been made to assist. For instances where an Amplifier may need to be mounted to a pipe, we manufactured a custom Stainless-Steel Adjustable Air Amplifier with class a 150 raised face flange.
  • Applications that are in a hot environment may require a special high temperature version which has be developed to operate in areas up to 700°F. The High Temperature Air Amplifier was so widely sought after that we turned it into a stock item.

No matter what your application is EXAIR is capable to work with you to create custom solutions for your application. Whether you need a different material, size or shim thickness, EXAIR is able to meet your requirements. These Air Amplifiers represent only one of our many product lines that can be custom made to your specifications.

Vortex Tubes can be Customized to Suit Your Application

Vortex tube

EXAIR’s Vortex Tubes are a low-cost, reliable, and maintenance-free solution to a variety of industrial spot cooling problems. With just an ordinary supply of compressed air, the Vortex Tube produces two streams of air: one hot and one cold. This is achieved without any moving parts or refrigerants!!

The Vortex Tube is capable of achieving a temperature drop/rise from your compressed air supply ranging from -50°F to +260°F (-46°C to +127°C). Flow rates range from 1-150 SCFM (28-4,248 SLPM) and refrigeration of up to 10,200 Btu/hr. With all Vortex Tubes constructed of stainless steel, they’re resistant to corrosion and oxidation ensuring you years of reliable, maintenance-free operation.

How A Vortex Tube Works

In addition to providing a range of different Vortex Tubes available to ship same-day from stock, EXAIR also has a few options available for cases where a stock Vortex Tube may not be the right solution. The standard Vortex Tube is suitable for use in environments with ambient temperatures up to 125°F (52°C) due to the plastic generator and Buna o-rings. For more extreme environments and ambient temperatures up to 200°F (93°C), we install a brass generator and replace the Buna o-rings with Viton seals.

All standard Vortex Tubes are adjustable. A small valve is located at the hot air exhaust end of the tube. Using a flat-tipped screwdriver, you can adjust the amount of air that is permitted to exhaust from the hot end. As more air is allowed to escape, the temperature at the cold end of the tube drops even further. The volume of air at the cold end as the temperature drops will also decrease. The percentage of air exhausting from the cold end relative to the total air consumption is referred to as the cold fraction percentage. Lower cold fractions will produce lower temperatures, but there won’t be as much volume. Finding the proper setting for your Vortex Tube can take some adjusting.

As we all know, if there’s a knob to turn, button to press, or adjustment that can be made an operator is inevitably going to tinker with it. Day shift will blame the night shift, night shift blames the day shift, and it can present a problem when the Vortex Tube has been specifically tested and set to achieve the desired cold fraction. If you know the cold fraction you need, but would prefer to prevent it from being able to be adjusted, EXAIR can install a precisely drilled hot plug to set the cold fraction percentage to your specifications and eliminate any potential for it to be changed.

If you’d still prefer to keep the adjustability, but don’t have the capabilities to measure and set it yourself, we can also set any Vortex Tube to the desired cold fraction with the adjustable valve and send it to you ready to be installed. We’ll provide you with a special model number so you can rest assured that any time you need another it’ll come set to your specification.

At EXAIR, we’re committed to providing you with the best solution possible for your application. Sometimes that isn’t going to be achievable with a standard stock product. Just because you don’t see it in the catalog or on our website, doesn’t mean we can’t do it. If you have a unique application and would like more information on getting a special Vortex Tube, contact an Application Engineer today.

EXAIR Super Air Knives: Customized for You

In a recent blog “EXAIR Super Air Knives: Overview”, I shared the features and benefits that puts the “Super” in the Super Air Knives.  But, let’s not define ourselves by our widest range of lengths and materials that we stock.  EXAIR can also customize the Super Air Knives to fit your requirements.  Many manufacturers like to make their standard items and expect the customers to adapt to their design.  But at EXAIR, customer service is our primary focus.

EXAIR manufactures our products at one location in Cincinnati, Ohio.  So, this gives us the flexibility to do many things like making adaptive configurations with our Super Air Knives.  Here are some examples that our customers requested.

  • Special lengths: EXAIR stocks standard incremental lengths from 3” (76mm) up to 108” (2.74 meters) in aluminum, 303SS, and 316SS materials; or 3” (76mm) to 54” (1,372mm) for PDVF Super Air Knives. But sometimes, the Super Air Knife has to fit into a specific area where a standard length will not work.  This is where EXAIR exceeds, and we can make any length metric or imperial between the ranges above.

    PVC Super Air Knife
  • Other materials: There isn’t a single material that is inert to all chemicals. In some rare cases, the environment can chemically attack our Stainless Steel or PVDF Super Air Knives.  So, a different material may have to be used.  For the customer above, they required a PVC material for a phosphorous environment.

    Curved and Thin Super Air Knives
  • Critical Dimensions: When the Super Air Knives have to adapt inside machines or in tight areas, we can modify the profile.  We have two special applications (reference above) that needed a design change for fit and function.  A curved Super Air Knife was used to hold tubes on a rotary table; and a thin Super Air Knife that was only 11/16” (17.5mm) thick cleaned a mold for circuit chips.

    Super Air Knife special mounting
  • Add-ons: EXAIR understands the importance of connecting to our Super Air Knives to get the greatest performance.  Our stock product has ¼” NPT inlet air ports along the bottom and one at each end.  We have ¼” – 20 threaded holes for mounting along the bottom as well.  But if you want threaded holes in a specific location for mounting or need the inlet air ports to be metric threads, EXAIR can accommodate these features.

    Double-sided Super Air Knife
  • Situational Applications:  Super Air Knives can have complex or simple changes depending on the application.  As an example, EXAIR created a design for a double-sided Super Air Knife to blow a laminar stream of air 180 degrees apart (reference photo above).   A simpler proposal was to replace the cap screws in a 316SS Super Air Knife with hygienic screws for food applications to remove crevices for bacterial growth.
  • OE Protection: In today’s market, it is important to protect your business.  At EXAIR, we can make a special Super Air Knife to blow, dry, or cool in your custom machines.  With a unique model number, EXAIR can help support and protect your business for future and replacement business.

Remember, your imagination is the beginning of creation.  If you cannot find a specific design to be used in your compressed air application, don’t give up.  Contact an Application Engineer at EXAIR to see if we can help you.  We have a team of engineers that can evaluate the fit and function to create a “Super” blow-off solution.  For the customers above, we were able to propose a unique Super Air Knife to work in their application; not the other way around.
