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.

Porous and Non-Porous E-Vac Vacuum Generators

Getting a vacuum from compressed air seems a bit like magic, but it works and it works well. EXAIR’s E-Vac® Vacuum Generators are compressed air powered, single stage vacuum generators. They are a low cost way to create vacuum for pick and place, clamping, lifting, chucking, vacuum forming and other applications.

The Low Vacuum Generators are ideal for ‘porous’ types of applications.  When we say ‘porous’ we are describing those processes where a lighter vacuum level combined with higher vacuum flows are needed. A good example of this is lifting a cardboard box. The cardboard is not air tight, and when you place a vacuum on it, air is able to be pulled through the cardboard. To maintain the vacuum level, the air needs to be able to be pulled through the cardboard and exhausted as fast as it is being pulled through in order to maintain the vacuum level. This requires higher vacuum flow and the design of the Low Vacuum Generator allows for the development of a good vacuum level and a high rate of vacuum flow.

The High Vacuum Generator is ideal for ‘non-porous’ type of applications. ‘Non-porous’ are those processes where the material is air tight, and no or very little air can pass through. Material such as glass, ceramic, and steel are ‘non-porous’. Because little or no air passes through, the need for high vacuum flow is not as important, and the highest of vacuum level can be achieved. A perfect vacuum is 29.92 in-Hg, and the High Vacuum Generator is designed to reach vacuum levels of 27 in-Hg, or a 90% vacuum level.

Both the Low Vacuum and High Vacuum Generators come in 7 different sizes, ranging from light to very strong vacuum capabilities, to match any application. Special Kits are  available as a way to experiment with an assortment of vacuum cups to determine the best configuration.

Custom Air Amplifiers for Special Applications from EXAIR

The EXAIR Super Air Amplifiers and Adjustable Air Amplifiers are used in 100’s if not 1000’s of applications and locations across the world.  For cooling, drying, and cleaning of parts as well as venting and exhausting of smokes and fumes, or dust collection – the Air Amplifiers are sure to get the job done.

The Super Air Amplifiers are made of aluminum and are sized from 3/4″ to 8″ to cover a wide range of applications. Compact and lightweight, no electricity, no moving parts, and instant on/off are just a few of the features.

The Adjustable Air Amplifiers are made of aluminum or type 303 stainless steel and are sized from 3/4″ to 4″, and with adjustable output, provide a wide spectrum of performance.  They have the same great features of the Super Air Amplifier with the added benefit of varying force and flow.

Even with the wide variety of types, sizes, and materials of construction, a customer may have a special need and there are numerous ways that EXAIR can customize the Air Amplifiers.  I’ll touch on several from the basics to the most complex.

  • The Super Air Amplifiers come with a stock shim that sets the performance seen in the catalog. There are other shim thicknesses available if more or less flow is preferred, and they can be installed at the factory if desired.
  • The Adjustable Air Amplifiers are designed for varying output by turning the plug further in to or out of the body. If there is a performance setting that is preferred, we can test, adjust and set it to meet that performance, allowing to be installed and ready for optimum results.
  • If the use of a special material will increase the benefit of the Air Amplifier, we can explore several options with you. One customer needed an Adjustable Air Amplifier with a PTFE plug to help draw a sticky material through a process and prevent the material from adhering to the surface of the Air Amplifier.
  • For those applications where the Air Amplifier is to be installed into a piping system, custom design with flanged ends can be done. Recent designs include stainless steel Adjustable Air Amplifiers with class 150 raised face flanges, and another with sanitary Tri-Clamp style.

  • A special High Temperature version was developed for moving hot air to surfaces requiring uniform heating while in a furnace or oven. This special design is rated for environments up to 700°F and its surface is protected from heat stress by a mil-spec coating process.  This special High Temperature Air Air Amplifier was so popular, it became a standard offering and is in stock!

How the Adjustable Spot Cooler WorksThe Adjustable Spot Cooler incorporates a vortex tube to convert a supply of compressed air (1) into two low pressure streams, one hot and one cold. With the turn of a knob, the temperature control valve (2) allows some hot air to flow through a muffling sleeve and out the hot air exhaust (3). The opposite end provides a cold air stream (4) that is muffled and discharged through the flexible hose, which directs it to the point of use. The swivel magnetic base (5) provides easy mounting and portability.


The Adjustable Spot Cooler can produce a wide range of air flows and temperatures as determined by the temperature control valve knob setting and the generator installed. The generator controls the total SCFM (SLPM) of compressed air consumption, and is easy to change. From the factory, the 25 SCFM (708 SLPM) generator is installed, producing up to 1,700 BTU/hr (429 Kcal/hr) of cooling. For less cooling, the 15 SCFM (425 SLPM) generator can be installed, providing up to 1,000 BTU/hr (252 Kcal/hr) of cooling. And for more cooling, the 30 SCFM (850 SLPM) generator can be installed, providing up to 2,000 BTU/hr (504 Kcal/hr) of cooling.

Adjustable Spot Cooler Specifications

Two (2) Systems are available as shown below, and include the 15 and 30 SCFM (425 and 850 SLPM) generators, a filter separator, and either a single or dual point hose kit.
