Accessories for Your Compressed Air Products

Published on by Al WooffittLeave a comment

Here at EXAIR we are very proud of our Intelligent Compressed Air Products. We have spent a lot of time discussing their many benefits, including their efficiency, the fact that many have no moving parts, little to no maintenance, meeting or exceeding OSHA safety standards for noise or dead end pressure. One thing we don’t talk as much about is the accessories that go along with and complement our products. Several of these accessory items are the reason why our compressed air products can boast about having little to no maintenance, or reduced noise levels. In this blog I want to cover some of these unsung heroes.

From left to right, a few value-added accessories for your Vortex Tube: Hot Muffler, Cold Muffler, Automatic Drain Filter Separator, Oil Removal Filter, and Solenoid Valve/Thermostat Kit.

Some of the most popular accessories we offer are our compressed air Filters and Regulators. We suggest using these with all our products (or even with ones that aren’t ours).

The Filter Separator is designed to remove moisture, dirt, and rust from your compressed air system. The 5-micron filter element ensures that contaminants don’t clog or harm your compressed air equipment.

An Oil Removal Filter (which should always be installed after our Filter Separator) provides even more precise filtration by getting rid of oil and solid particles with a 0.03-micron element.

Our Pressure Regulators let you choose the operating pressure. At EXAIR, we always advise running at the lowest pressure necessary to complete the task. Pressure Regulators help you achieve that, reducing unnecessary air usage and fine-tuning the performance of EXAIR products for your specific application.

We have some accessories designed specifically for certain products. For our Line Vacs, there’s the Line Vac Hose. You can also find Thermostats and Solenoid Valves that work great with our Cabinet Coolers, and if you’re using Vortex Tubes, we suggest checking out our Mufflers.

When it comes to our Air Knives, we offer a variety of fantastic options:

If you’re looking for a simple and dependable way to mount your Air Knife, our Universal Air Knife Mounting System is just what you need.

If your project needs something longer than our stock Air Knives, or if you want to manage different sections of the air flow separately, our Coupling Bracket Kits are ideal.

And if you want to simplify the plumbing for your Air Knife, don’t miss our Air Knife Plumbing Kits. They’re suitable for all Air Knives that are longer than 24 inches.

If you’re looking for plumbing options, we’ve got a range of compressed air hoses and fittings that will simplify things for you.

Our Coiled Hoses work great with our Safety Air Guns, giving you more freedom of movement while you work.

Our Compressed Air Hoses are often used alongside our Industrial Housekeeping products to provide the necessary reach for the drum and dolly.

Finally, if you’re looking for a way to mount or position your Air Nozzles, check out our Magnetic Bases, Stay Set Hoses, and Swivel Fittings that can help create a complete setup.

No matter what your application requires or the product you need, we’ve got a variety of complementary accessory products that will simplify installation and adjustments. If you have any questions about these or any other EXAIR products, don’t hesitate to reach out to us.

What Is a Centrifugal Air Compressor? How It Works and Why It’s Used in Industry

Published on by Tyler DanielLeave a comment

One thing that’s found in nearly every industrial environment is an air compressor. Compressed air is used to power tools, operate packaging and automation systems, run conveyors, control valves, and more. Pneumatic tools remain popular because they’re smaller and lighter than their electric counterparts, offer infinitely variable speed and torque, and can often be safer than electrical devices in harsh or wet environments.

To power these systems, compressed air must first be generated, and that starts with the air compressor. There are two main categories of air compressors: positive displacement and dynamic. Positive displacement compressors trap a given quantity of air in a chamber, then mechanically reduce the volume to increase the pressure. Dynamic compressors raise air pressure by accelerating continuously flowing air with a high-speed impeller. The velocity energy of the air is then converted into pressure energy.

One of the most common dynamic types used in industrial applications is the centrifugal air compressor. In a centrifugal compressor, air enters the center of a high-speed rotating impeller, which can spin at more than 50,000 RPM. The impeller’s blades fling the air outward by centrifugal force, increasing its velocity and pressure. The kinetic energy of the moving air is then converted into additional pressure as it slows down in a diffuser. Centrifugal compressors are generally used where large volumes of air are required. They can handle flows from a few hundred CFM up to 100,000 CFM or more, with most plant installations falling in the 1,000–5,000 CFM range.

According to the Compressed Air Challenge, some of the key benefits of centrifugal air compressors include their ability to deliver oil-free, contaminant-free air, and the fact that they are often supplied as complete packaged systems up to 1,000 HP. They scale well, as the cost per CFM improves as size increases, do not require special foundation requirements, and are ideal for high-volume air delivery.

Of course, there are trade-offs to consider. Centrifugal compressors have limited capacity control options, reduced efficiency at partial load, and their high rotational speeds require precision bearings and specialized maintenance. They also tend to have a higher initial purchase cost compared to smaller positive-displacement units. Despite these considerations, centrifugal air compressors remain a reliable choice for facilities that require large, continuous volumes of clean, oil-free air.

Once your facility’s air is generated, the next step is making sure it’s used efficiently. Compressed air is one of the most expensive utilities in a plant, and any wasted air means wasted energy. That’s where EXAIR’s line of engineered Air Nozzles, Safety Air Guns, Super Air Knives, and Optimization products come into play, helping you get the most from every SCFM your compressor produces. If you’re looking to improve your system’s efficiency or solve a specific application issue, contact one of our Application Engineers. We’ll help you get the most out of your compressed air system from the compressor room to the point of use.

Week 3 Back to Basics – Replace Inefficient Blowoffs

Published on by Brian FarnoLeave a comment

In the last post of this series, we talked about finding and fixing leaks in your compressed air system. Many readers found that step especially valuable—leak detection alone can uncover major savings opportunities. Now, it’s time to move on to step three in the Six Steps to Optimizing Your Compressed Air System: implementing engineered solutions.

Engineered solutions (like EXAIR Intelligent Compressed Air Products) are the efficient, quiet, and safe choice.

This is where our Application Engineers can really help. Whether your application calls for Air Knives, Super Air Nozzles, or another one of our engineered products, we can guide you to the right solution. If you already know the consumption rates of your existing setup, we can even help you calculate the savings you’ll see by switching.

Step three is often where customers begin to notice the biggest impact. Replacing an open pipe or a non-engineered blowoff with an engineered solution can drastically reduce compressed air usage. The difference becomes obvious when your compressor cycles less frequently—or in some cases, when you’re able to shut down a secondary compressor altogether.

In the next post of this series, we’ll cover step four: an even simpler way to extend your savings by turning air off when it isn’t needed. Until then, keep working toward a more efficient compressed air system.

Customize Your Safety Air Gun to Best Meet Your Needs

Published on by Al WooffittLeave a comment

EXAIR has an extensive line of Safety Air Guns that will meet a variety of applications. Our VariBlast Precision, Compact, Soft Grip, Heavy Duty and Super Blast Safety Air Guns, and TurboBlast will give you a wide range of options to choose from. These options can be expanded on even further through the addition of our Air Gun Accessories. In this blog I want to cover a few of the ways you can customize and personalize your Safety Air Gun to make sure you are getting the most out of our products.

Features & benefits of the new TurboBlast Safety Air Gun

Once you have selected your particular Air Gun, you will want to make sure that you have the right nozzle. Every Air Gun has multiple nozzle options with different force and flow specifications. If your main concern is low sound levels, then the Mini Super Air Nozzle may be the best option. If you need more force, then the 2″ High Power Flat Super Air Nozzle would be preferred. We also have Back Blow Nozzles that are great for blind holes.

In addition to this, there are several different material choices. Zinc-aluminum for general purposes, Type 303 stainless steel for corrosion resistance, Type 316 stainless steel for superior corrosion resistance and mechanical wear, and finally PEEK thermoplastic for non-marring and chemical resistance.

Model 1210 Soft Grip Safety Air is fitted with an EXAIR Super Air Nozzle. We can also supply it with a Rigid Extension and Chip Shield (right).

After you have determined the right nozzle, do you need to add a Chip Shield? If you have the potential for flying debris, and you want to protect your operator, then our Safety Air Guns can be equipped with a durable polycarbonate shield. They are also useful for preventing coolant from splashing back, helping you to avoid a mess. You can see a Chip Shield in action in the video below:

We also have various length extensions for when you need more reach for your blowoff operation. Depending on the Air Gun, we have lengths ranging from six inches to six feet. These are great when used in conjunction with our Chip Shields. If you need something more flexible than a straight extension, our Soft Grip Safety Air Gun can also be used with our Stay Set Hoses. These hose have a ‘memory’ to allow for precise positioning without creeping or bending.

Specifically with our Soft Grip Safety Air Gun, we have a special extension and scraper combination, covered in detail in this blog. The Soft Grip Super Air Scraper is highly effective at removing stubborn debris from various surfaces.

Coiled Hose

Finally, we stock a 12‘ coiled air hose. These are available with 1/8NPT, 1/4NPT and 3/8NPT male end swivel connections. This will help you avoid messy and tangled air lines.
