Air Nozzles and Air Jets: An Overview

One of the simplest solutions to lower your air consumption and noise level when it comes to compressed air is to switch your open tubes or pipes and liquid nozzles which are being used for air applications to an engineered compressed air nozzle. EXAIR’s Engineered Air Nozzles and Jets provide a simple solution for a wide variety blow off and compressed air applications and can solve a multitude of process problems efficiently. These applications can include simple blow offs, cooling, part ejection, and much more.

Super Air Nozzles:
Super Air Nozzles are one of the more versatile of all of EXAIR’s Engineered Air Nozzles. They come in many different sizes from a tiny size of M4 threads and 13 millimeters long to the largest with  1-1/4 NPT threads which has a 2″ hex and is almost 5″ long. These are usually used for standard blow off applications that replace open pipes to reduce your air consumption and noise. The force values vary from 2 ounces to 23 pounds of force. 

Another variation of the Super Air Nozzles is the Flat Super Air Nozzles; these nozzles create a small flat curtain of air at a high force to provide a wider blow off area for smaller NPT sized nozzles. The 1” and 2” Flat Super Air Nozzle also have replaceable shims that allow you to adjust the force coming out of the nozzle by increasing the amount of air that is used.

Back Blow Air Nozzles:
Back Blow Air Nozzles are designed in a way that blows that makes it easy to blow out the inside of pipes. The Back Blow Air Nozzles have holes around the outside diameter pointed back that creates a cone of air around the air inlet port. This makes it easy to dislodge clogs in pipes that you don’t want going back into the machine and for blowing out liquid and debris from the inside. They are also commonly used with EXAIR’s Chip Shield as to prevent any particles from flying back and hitting the user. Back Blow Air Nozzles come in three sizes: M4, ¼”, and 1” and can be used on inside diameters ranging from ¼” to 16”.

Super Air Nozzle Clusters:
Super Air Nozzle Clusters use a number of the ¼” Super Air Nozzles to create one nozzle that has a wider cone and larger force. Clusters are usually used in wide area blow off but can also be used for part cooling and part reject as they do supply a wider area of force. Super Air Nozzle Clusters are sized by the number of nozzles in the cluster; the three sizes that we offer are 4-nozzle cluster (3/8” NPT inlet), 7-nozzle cluster (1/2” NPT inlet), and the 12-nozzle cluster (1” NPT inlet).

Air Jets:
Air Jets amplify the total volume of air into a high velocity stream of air. This makes it very useful for blowing off/drying applications and cooling applications due to the higher volume of air flowing through the unit. Air Jets come in two variations which are the High Velocity Air Jet and the Adjustable Air Jets. The High Velocity Air Jet uses a 0.015” shim that allows the air to escape the unit at a high velocity laminar flow to entrain the surrounding ambient air; this can be adjusted down using the shim kit which includes a 0.006” and 0.009” shims. The Adjustable Air Jet allows the user to easily adjust the air gap using the micrometer gap indicator.

Flat Super Air Nozzles by EXAIR: A Wide-Range of Customizable Solutions

EXAIR’s Flat Super Air Nozzles have been blowing away the competition since 2003.

EXAIR’s line of 1” and 2” Flat Super Air Nozzles are rugged, efficient, and ideal for applications that require a wide forceful stream of airflow. The patented design utilizes a special shim to maintain the critical position of the component parts. The result is a laminar, high velocity blast of air with minimum air consumption and sound level.

The Flat Super Air Nozzles are available in a wide range of configurations. With both the 1” and 2” sizes you have the ability to select either Zinc Aluminum alloy or Type 316 Stainless Steel for higher temperature or corrosive applications. They’re also available installed at the end of our Safety Air Guns. The 1” Flat Super Air Nozzles are ideal for our VariBlast Compact Safety Air Gun while the 2” is suitable on either our Soft Grip Safety Air Gun or the Heavy Duty Safety Air Gun.

With extensions ranging from 6”-72” and Chip Shields also available, you have the ability to tailor a blowoff gun to your exact application. Since the design of the nozzle prevents any chance for it to be dead-ended, all configurations will be compliant with OSHA directive 29 CFR 1910.242(b). This means you’re able to operate at pressures in excess of 30 PSIG without risking harm to your operators.

In addition to two different sizes and materials, there’s also a wide range of shims that can be installed. Just like the Super Air Knife, the thickness of the shim installed (in addition to the input compressed air pressure) will dictate the force and flow through the nozzle. For both the 1” and 2” Flat Super Air Nozzles, shim thicknesses are available ranging from .005”-.030”. Thicker shims will increase the force and flow, thinner shims will reduce it while also reducing the air consumption. To allow you to experiment with different flows, we make shim sets available that’ll allow you to test out a few different sizes in order to determine the best solution for your application.

New to EXAIR in 2018, the Model 1144 2” Super Air Scraper is a patent pending nozzle used to remove stuck-on debris from work or machine surfaces. It incorporates a strong corrosion resistant scraper blade to add necessary leverage to allow you to get underneath and scrape away debris. The strong airflow from the 2” Flat Super Air Nozzle then is able to get underneath and blow away the material. The scraper nozzle is great for applications involving the removal of tape from floors, gaskets, adhesive, labels and stickers, grease, paint and sealant. It’s also available on the end of our Soft Grip Safety Air Gun with durable ¾” air extensions in lengths ranging from 6”-72” and Chip Shields. All of these possibilities are available from stock with same day shipments.

Utility Rebates for Energy Savings

Since the establishment of EXAIR in 1983, customer satisfaction has always been the cornerstone of our business model.   This may seem like a common practice, but here at EXAIR, we like to go the extra mile.  We have over a 99.9% on-time delivery with thousands of products in stock.  We offer free expert technical help from our Application Engineers, as well as within EXAIR Blog writings and application search library.  We have an Efficiency Lab to report on comparison results with safety and compressed air saving.  We also offer a 30-day unconditional guarantee on our cataloged products for you to try.   So, what more can EXAIR do for you?

Free testing. Verifiable data. EXAIR Efficiency Lab.

Compressors use large amounts of electricity to produce compressed air and are considered the fourth utility in most manufacturing plants.  EXAIR manufactures engineered products that can save compressed air and increase energy savings.  With that, EXAIR was able to partner with Energy Star.  “Energy Star is a government-backed symbol for energy efficiency helping to save money and to protect the environment through energy-efficient products and practices.” This commitment by EXAIR for reducing energy, increase safety for workers, and protecting the environment for future generations are effective ways to sustain a business value.

When large amounts of energy can be saved, electricity producing companies take notice.  Electrical suppliers started a rebate program for using engineered nozzles in their facility.  Similar to other energy-saving rebates, like LED light bulbs and high-efficiency furnaces, EXAIR engineered nozzles now fall into that same category.  If your electrical provider supports this program, the total cost to purchase and implement the EXAIR Super Air Nozzles are greatly reduced.  Even if a rebate program has not yet been implemented in your area, the idea of saving energy makes it very practical and environmentally sound.

The NC Clean Energy Technology Center created a website to consolidate all the electrical companies that offer rebates for efficient products and programs.  The website is www.dsireusa.org.  “DSIRE is the most comprehensive source of information on incentives and policies that support renewable and energy efficiency in the United States.”  EXAIR engineered products fall into this category, so if a rebate can be applied to our products, it will be located on that site.

Back to the question above, what more can EXAIR do for you?  We all live busy lives at work and at home.  It may be difficult to find the proper programs from your local power companies.  Let EXAIR do most of the legwork for you.  Per your request, we can help find the proper forms for rebates when switching to EXAIR engineered nozzles.  With a rebate program, it makes it very cost effective to upgrade your pneumatic system to an energy efficient system.

Being backed by Energy Star, EPA, and rebate programs, together, we can save energy, improve the environment, and reduce compressed air usage.  If you would like to discuss how EXAIR can work for you, you can contact an EXAIR Application Engineer to get the most out of that extra mile.

EXAIR Flat Super Air Nozzles – Adjustable, Flexible and Powerful

As an Application Engineer here at EXAIR, we get calls from customers looking for an air knife, but shorter than our typical 3″ stocked size.  We can make an air knife to any length needed, but we will look at the 1″ and 2″ Flat Super Air Nozzles as a possible solution.

Like an air knife, the Flat Nozzles provide a wedge shaped pattern of air that maintains the width of the nozzle, to create a concentrated, powerful air flow.  Thus, a 1″ Flat Super Air Nozzle has air stream 1″ wide, and the 2″ Flat Super Air Nozzle has one 2″ wide.

The Flat Super Air Nozzles are available in zinc aluminum alloy or type 316 stainless steel construction, to meet environmental conditions of the process.  Both the 1″ and 2″ nozzles contain a changeable, patented shim that maintains the critical air gap, which allows the release of a precise amount of air through the thin slot, across a flat surface. The result is a wide, forceful stream of high velocity, laminar airflow, with minimal air consumption and noise.
