Industrial Air Gun Accessories For Safety And Convenience

The words “safety” and “convenience” are rarely synonymous. Many times, in fact, they are seemingly at odds with one other:

  • Decades of data absolutely prove the importance of wearing a seat belt in a motor vehicle. In the dead of winter, when I’m wearing a heavy coat and gloves, it can be cumbersome to pull that belt across me and fasten it without removing those gloves that are protecting my sensitive hands from the brutal cold. I do it anyway, and so should you.
  • I don’t own a boat, but I have friends that do, and I find it hard to pass up an invitation to spend a nice summer afternoon water skiing, tubing, or just cruising down the river. Life vests on a hot sunny day are perhaps just as cumbersome as seat belts. No matter how good you can swim, though, there’s a big difference between jumping in the water for a refreshing dip and being thrown into the water after a collision with an unseen object. If you’re unconscious, or even just disoriented, that vest will save your life.
  • If you work in an area where you’re supposed to wear safety glasses (even if they fog up) or ear plugs (actually, if they’re uncomfortable, you have the wrong ones…or you’re using them wrong), they’re a miniscule inconvenience compared to losing your sight or your hearing.

Notice I said “seemingly at odds” above, because safety doesn’t HAVE to be inconvenient. I could trade my old bulky insulated gloves for a newer pair made of thinner material that still have decent insulation. People who boat regularly will have properly sized life vests (instead of one-size-fits-most) with snap buckles (instead of pull straps). There are a number of different styles of safety glasses and anti-fogging treatments for the lenses, for long term use in most any environment. Likewise for hearing protection – whether you like the headset-style that covers the ears, or plugs that insert into your ear canals, there are comfortable designs, and some neat technology that cancels harmful sound frequencies so you can even carry on a conversation, even in a loud environment.

EXAIR Corporation has a long history of adding convenience to compressed air use, while remaining well within the confines of safety (that’s something we don’t cut corners on in our products, operations, or company culture) and efficiency. We’ve got accessories, add-ons, tools, etc., for most of our product lines. It’s quite prevalent in our Safety Air Guns product line, and for good reason – there are a number of areas where some flexibility regarding the use of handheld tools not only add convenience, but also contribute even further to their safe use. Consider:

  • Reach. When blowoff needs to happen inside, behind, under, or over an obstruction, extensions are available for any EXAIR Safety Air Gun, so operators can keep their hands free of the obstruction, especially if it’s hot, sharp (or otherwise potentially harmful) or just dirty or wet.
  • Cleanliness. While they’re usually specified to comply with OSHA regulations regarding proper chip guarding while using compressed air for cleaning, Chip Shields also prevent the nuisance of getting yourself dirty or wet from blown off debris. They’re available on all our compressed Air Blow Guns except for the Super Blast models.
  • Reach, part 2. A particularly nifty little option on the Soft Grip Safety Air Guns is the ability to use a Stay Set Hose (as opposed to a Rigid Extension) for extra reach. Let’s say you have to get back to, and behind, an obstruction for blowoff. Simply bend the end of the Stay Set Hose to the angle required, and you’re in business! They come in lengths from 6″ to 36″ long.
  • Stubborn debris. Among the new products that EXAIR has introduced over the past few years, this one is my personal favorite: the Soft Grip Super Air Scraper. We took our 2″ Flat Super Air Nozzle and put a steel scraper blade on it, which assists the air flow by scraping (as the name implies) caulk, gaskets, sealants, tape, paint, etc., off the surface, as the air flow blows it away! It’s the perfect “one-two punch” for applications like these.
In addition to a variety of engineered Air Nozzles, you can customize your EXAIR Safety Air Gun with Chip Shields, Extensions, Stay Set Hoses, etc., to meet the particular needs of a specific application.

If you already have serviceable air guns that operators are used to and comfortable with (first law of human nature is “change is bad,” right?), all of our Super Air Nozzles have NPT threads…you may only be an adapter away from installing them on your existing devices. Speaking of adapters, we also stock a number of the “usual suspects” – an EXAIR Application Engineer can help you determine what your air guns’ existing threads are.

Thumb guns are convenient and inexpensive. Ones with cross drilled nozzles (left) are compliant with the first part of OSHA 1910.242(b). Fitting one with an EXAIR Chip Shield (center) makes it compliant with the second part. A Model 1102 Mini Super Air Nozzle (right) makes it quiet & efficient.

EXAIR Corporation offers a broad selection of quiet, safe, and efficient compressed air products, and one of the most comprehensive selections of handheld solutions in the industry. Whatever your need for a Safety Air Gun is, we most likely have you covered. Call me; let’s talk.

Optimize Your Intelligent Compressed Air® Products with EXAIR’s Accessories

EXAIR offers a wide variety of various accessories that can help you to better control and fine-tune any of your compressed air operated products. Most of EXAIR’s line of Intelligent Compressed Air Products have no moving parts and require no maintenance. The caveat to the “no maintenance” aspect is proper filtration at the point of use. Many products have very tight orifices that could get clogged from any contaminants such as particulate, condensate, and lubricant. EXAIR recommends point of use filtration to be installed just upstream of any EXAIR Product for this purpose.

EXAIR has a line of Automatic Drain Filter Separators and Oil Removal Filters, available from stock, to make sure the quality of your air supply is sufficient for proper operation of any EXAIR product. Particulate filters remove any suspended solids from the airstream, ensuring the tight orifices in the products remain free of debris. If your system has residual oil, this should also be removed with a coalescing filter. Check out this short video from my colleague, Brian Farno, that demonstrates these filters in action:

Controlling your compressed air pressure at the point of use is an excellent way of minimizing your compressed air usage. Pressure regulators are available to control the air pressure within the system and throttle the appropriate supply of air to any pneumatic device. As the last of the six steps to optimizing your compressed air system, controlling air at the point of use can often be overlooked. using them to minimize your pressure can result in dramatic savings to your costs of compressed air. As pressure and flow are directly related, lowering the pressure supplied results in less compressed air usage. EXAIR recommends operating your Intelligent Compressed Air Products at the minimum pressure necessary to achieve a successful application. If you notice a desirable result at a pressure of 60 PSIG, or even less, there’s no need to run full line pressure. In-line point of use pressure regulators are the simplest and most reliable way to allow you to dial down to the pressure to any compressed air operated product.

Taking this idea of minimizing air usage one step further, you can achieve even greater savings by simply turning the air off when not needed. The most basic option for turning off the air supply is a simple manual valve. EXAIR offers a range of various sized valves to allow you to do just that.

This process can also be automated as well. If you’d like to automate the control of your blowoff, EXAIR offers solenoid valves that can tie into your existing PLC and eliminate unnecessary air usage. For those that want a solution ready to go right out of the box, EXAIR’s Electronic Flow Controller utilizes a photoelectric sensor and solenoid valve tied to a timer that allows you to shut off the air supply when a part or component is not present. This can lead to dramatic air savings in many applications where parts are traveling along a conveyor.

Once you’ve selected an engineered compressed air nozzle for your blow off application, you’ll likely need a solution to mount and position it as well. Here’s where EXAIR’s Stay Set Hoses and Magnetic Bases come into play. EXAIR’s Stay Set Hoses are available from 6”-36” in length with ¼ NPT male threads on each end, or a ¼ NPT male on one end and 1/8 NPT female on the other. The Stay Set Hoses are rigid and allow you to maintain precise positioning of the blow off nozzle. The hoses have “memory” and will not creep or bend. They’re easily repositionable as well, making them an ideal solution for applications that may require frequent repositioning due to varying parts.

In addition to the Stay Set Hoses, EXAIR also has Magnetic Bases available as well. The powerful magnet permits both horizontal and vertical mounting. A manual valve is also included that will allow you to vary the force and flow. Magnetic bases are available with one or two outlets and can be combined with any of our nozzles and Stay Set Hoses to create your own customized blowoff system.

Regardless of your application, EXAIR has the products available from stock to help optimize your processes. These accessories allow you to help optimize the use of your blowoff products and ensure reliable, repeatable performance. If you’d like to discuss an application, give us a call.

EXAIR E-Vac Vacuum Generator Accessories: Overview

Vacuum systems are becoming more and more prevalent within manufacturing day by day. Vacuum powered lifts can make it easy to lift and move small objects like tiny coins to heavy steel plates. Vacuum chucks hold work pieces that could be marred by jaws or vises. And sealed vessels can be pressure tested or tested for leaks by pulling a vacuum on them. It’s pretty simple to pick out which vacuum generator that you need, but what about the accessories? There are so many different accessories to choose from such as mufflers, suction cups, hose, valves, and connections. The following is a quick overview of the different accessories that you can get from EXAIR along with your E-Vac vacuum generator.

Vacuum cups for E-Vac generators

Suction cups are a very common accessory that you need when using a vacuum system. Vacuum cups allow one to create a seal on the surface of the object that you wish to pick up and is what allows the system to lift objects. We offer four different kinds of vacuum cups to choose from stock; available are small and large Round, Oval, and Bellow styles. Round cups are more suited to being used on smooth, flat surfaces. Oval cups provide the most vacuum due to the larger surface area making them ideal for lifting heavy loads. The Bellows style is best suited for textured or uneven surfaces; the folds provide a collapsible area that allows the cup to compress and seal on an uneven surface.

EXAIR’s Standard and Straight Through Muffler

Next up is the mufflers; they muffle the sound generated by the E-Vac and quiet a working vacuum generator. There are two different types of mufflers from EXAIR that are available; these are the Standard and the straight through mufflers. The Standard muffler is designed to be attached to the discharge end of an in-line E-Vac and has a closed end. These are best suited for applications that are free from dust and debris. The straight through muffler is open all the way through and are more suited to applications were dirt, dust and debris is present. The straight through style also offers the best sound level reduction, up to 26 dBA.

Lastly the E-Vacs have an NPT threaded connection that will allow for a suitable connector to be properly installed. From here different connectors can be used to attach the various amounts of vacuum cups. The connectors provided are Push-In Connector Type Fittings of assorted styles available with our polyurethane tubing to make the installation and plumbing a cinch.

If you have any questions or want more information on EXAIR’s E-Vacs and their Accessories. Give us a call, we have a team of application engineers ready to answer your questions and recommend a solution for your applications.

Vortex Tubes – The Basics, And Beyond

The Vortex Tube might be just about the most interesting compressed air device around.  They have no moving parts, and they don’t need any but a compressed air supply, which they ‘split’ into a hot air stream, and a cold air stream.

EXAIR Vortex Tubes come in three sizes – Small, Medium, and Large – and 24 distinct Models across those three sizes.  They’re all in stock, along with Hot & Cold Mufflers (for sound level reduction,) Automatic Drain Filter Separators (to keep the air supply clean & moisture free,) Oil Removal Filters (to coalesce any trace of oil from the air supply,) and Solenoid Valves & Thermostats (to automate operation.)

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.

The Vortex Tube, right out of the box, is easily adaptable to a wide range of cooling (or heating) applications.  If your needs are specific, though, we can customize a Vortex Tube to meet them:

  • Material of construction: our stock Vortex Tubes are made of 303SS and are equipped with a plastic Generator and Buna o-ring.
    • For high temperature (>125F ambient) applications, we can install a brass Generator and Viton o-ring, suitable for ambient temperatures up to 200F.
    • If the environment is particularly aggressive, or if industry codes (I’m looking at you, food & pharma) call for it, we can also make them out of other materials.  We’ve, for instance, made them out of 316SS, complete with material certifications, when needed.
  • Flow & temperature: the Hot Valve can be opened or closed to dial in a particular Cold Fraction (that’s the percentage of the supply air which is directed to the cold end.)  If you know what flow rate and temperature you want, we can replace the Hot Valve with a non-adjustable plug, so your Vortex Tube’s cold flow is only dependent on the compressed air supply temperature and pressure.
  • Accessories: if you’re looking for features like a magnetic base, or a flexible cold air hose, you might consider an Adjustable Spot Cooler.  If you like the idea of tool-free change of air flow/temperature, that’s definitely the way to go.  If you want those other options, and don’t mind using a screwdriver to adjust the Cold Fraction, those other options are compatible with any Medium Vortex Tube.

Model 3925 Adjustable Spot Cooler

These are just a few of the most common possibilities for customizing a Vortex Tube.  If you have a spot cooling application you’d like to discuss, give me a call.
