Customizing Air Amplifiers

EXAIR’s line of Air Amplifiers can be found in a multitude of different applications across the world. They solve problems as simple as blowing debris off parts to exhausting fumes or circulating air. 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”.

The main difference between the Super Air Amplifier and the Adjustable Air Amplifier is the fact the Super Air Amplifier has a shim inside of it that sets the gap for the air flow. The standard shim thickness for the Super Air Amplifier in sizes of 3/4″ to the 4″ is 0.003” which is suitable for most applications. These shims can be exchanged for a thicker shim of thickness of either 0.006″ or 0.009″. The 8″ Super Air Amplifier is the only air amplifier that comes with a standard stock shim of 0.009″ and can be exchanged for a 0.015″ shim if needed.

Even though there is a wide variety of sizes and materials for the Stock Air Amplifiers they may not meet a customer’s specific application or need. Over the years EXAIR has produced many different custom Air Amplifiers for a customer’s specific need and the images throughout this blog are just a few of what we have done.

High Temp Air Amplifier

• 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 form depositing on the Amplifier.
• For applications were mounting may be an issue, special attachments have been made to assist. For instances were an Amplifier may need to be mounted to a pipe a custom Stainless-Steel Adjustable Air Amplifier with a class 150 raised face flanges.
• 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. It is commonly used in large roto-molds and ovens to circulate air in order to maintain consistent temperatures.

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.

For more information on EXAIR’s Line Vacs or help with customizing any of EXAIR‘s Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

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.

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.
