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 Celebrates Manufacturing Day With A Win For A Manufacturer

In 2012, the National Association of Manufacturers organized an effort to proclaim the first Friday in October (hey, that’s today!) as Manufacturing Day.  According to the Advanced Manufacturing National Program Office (a division of NIST, the National Institute of Standards & Testing,) the purpose of MFG Day is “to raise awareness among students, parents, educators and the general public about modern manufacturing and the rewarding careers available.”

Today is kind of a big deal around here.  Not only is EXAIR Corporation a manufacturer, but many of the companies that use our products are as well.  A lot of us have a rich story, woven into the cloth of the history of American manufacturing (which, in turn, is woven into the larger cloth of American history.)  Have you heard the one about the motivated inventor with an idea to make innovative products who started an operation out of his home that, with inspired direction & vision, became a worldwide leader in their industry?

Yeah; that’s us.  Today, we’re honoring Roy Sweeney’s legacy (he founded the company in October 1983,) and celebrating MFG Day, by publishing a new Case Study, proving out the benefits of the use of EXAIR Intelligent Compressed Air Products in regard to the monetary savings associated with the reduction in compressed air use, and the noise level reduction from the implementation of our engineered products.

You can download the complete Case Study here, but while we’re on the subject, here’s a basic rundown:

  • A roll forming operation used to blow off their product with a combination of loud and inefficient devices: copper tubing and modular flexible hose which is designed primarily for machine tool coolant, but often misapplied for use with compressed air.
  • It worked just fine, but an engineering study noted it as a potential wasteful use of compressed air.  That’s when they called us.
  • By replacing those blow offs with Model 1100 Super Air Nozzles and Model 1122 2″ Flat Super Air Nozzles, their noise levels dropped from 107 dBA to 83.8 dBA.  To put that in perspective, it went from the approximate sound level of a rock concert to that of a leaf blower. (ref: Centers for Disease Control & Prevention: What Causes Hearing Loss?)
  • Compressed air consumption dropped by more than half, from 190 SCFM to 86.8 SCFM…an annual savings of over $3,200.00.  All for an investment of $654.00 (2020 pricing) for those engineered Air Nozzles, Stay Set Hoses, and Magnetic Bases.  That means they’ll have paid for themselves in just under two months.
  • In addition to that, for participation in this Case Study, we’re giving them a generous credit on their order.  Happy Manufacturing Day!

And frankly, I think the engineered products just look better too.

Last but certainly not least, this reduction in compressed air usage decreases the load on their air compressors, reducing the electrical power consumed.  Product impact, along with our own consumption of resources and waste recycling, is a key component of EXAIR Corporation’s Sustainability Plan.  We’re making the world a better place, by making products that make the world a better place, using methods that make the world a better place.  I can’t think of a better way to celebrate Manufacturing Day.  If you want to get in on it, give me a call.

Accessories, Don’t Forget About Accessories!

Accessories

I went to the auto parts store to replace my brakes on my vehicle.  They asked me if I needed some Anti-squeak grease for my brake hardware.  It made me think about the accessories that EXAIR sells.  I could have used my own kind of grease which may not be able to hold up to the heat, but for a few dollars more, I wanted to go with the item that the experts would suggest.

In this blog, I would like to turn your attention to the accessories that support our Intelligent Compressed Air® Products.  EXAIR products use compressed air to coat, conserve, cool, convey and clean.  To maximize the performance and/or ease installation it is important to have the controls and options, and EXAIR offers these items as Accessories.

Pneumatic applications come in many variations and forms, and Accessories can help you to adapt to your application and to remove “guess work”.  They can make installation easier, add flexibility, and give you peace of mind.

Here are the different categories and explanations for each item that EXAIR recommends for our products with their defined functions.  They can help you in different areas to enhance your EXAIR product experience.

Automatic Drain Filter Separator (left,) and a Pressure Regulator (right.) Oil Removal Filters (optional; center) are also available if needed.

Filters/Regulators:

  • Filter Separators remove bulk liquid and contamination from the compressed air stream. EXAIR stocks a range of sizes from ¼” NPT ports to 1 ¼” NPT ports.  They use a 5-micron filter and a mechanical baffle to remove slugs of liquid from your compressed air system.  Most Filter Separators have an auto-drain to automatically remove the buildup of liquid inside the bowl.   I would consider the Filter Separator as a minimum level of protection required to protect your EXAIR product installations.
  • Oil Removal Filters remove very small particles of dirt and oil from the compressed air; making it even cleaner. The 0.03-micron media of the Oil Removal Filter will “coalesce” the fine liquid particles into large droplets.  Thus, allowing gravity to remove oil vapor from the compressed air stream.  EXAIR offers different sizes ranging from ¼” NPT to 1 ½” NPT ports.  As a note, Oil Removal Filters are great for removing very fine particles, but if you have a system with lots of water, I would recommend a Filter Separator upstream of the Oil Removal Filter for optimal filtration.
  • Regulators control the amount of air pressure being supplied to your EXAIR product. This is important if you are trying to save compressed air, control the force produced by an Air Knife, or convey material slowly.  EXAIR, being a leader in compressed air savings, recommends to use the minimum amount of air pressure to do the job.  This will save compressed air and save you money.  Regulators have a characteristic called “droop”.  Droop is the amount of air pressure that it drops downstream when you start flowing compressed air.  If the regulator is not sized properly, you can “starve” your pneumatic components, causing loss of function.  EXAIR properly sizes our regulators in our kits to make sure that you won’t “starve” your application.
  • Mounting Brackets for the regulators and the filters to help support them to a wall or structure are available. To connect filters and regulators together without a pipe nipple, we also have Coupling Kits for sizes up to ¾” NPT.  And for combination kits which includes a filter and a regulator, we offer the Mounting Bracket and Coupling Kit together for a set.

Silencing Mufflers:

  • Reclassifying Mufflers are designed to have two functions. They can cut noise levels by 35 dB and remove oil mist from the exhaust air.  Cylinders and valves that exhaust pressurized air may have oil in the line to keep the seals from sticking.  When exhausted, it can create a fine mist which is dangerous for operators.  The Reclassifying Mufflers can reduce the loud noise as well as collect any contamination from the exhaust air.
  • Sintered Bronze Mufflers are simple in design, cost effective, and easy to install. They have a minimal back pressure to not restrict operations of the pneumatic device.  They come in sizes from #10-32 thread to 1-1/2 NPT.  For a quick and simple way to reduce noise, the Sintered Bronze Mufflers are in stock for fast delivery.
  • Straight-Through Mufflers offer a way to reduce noise levels without worrying about clogging. They have an aluminum shell lined with sound absorbing foam, and they can reduce the noise level by 20 dB.  EXAIR offers them with two ports from ¼” NPT to ¾” NPT.  This can allow you to connect other items like blowing hose kits while reducing noise.
  • Heavy Duty Mufflers have an outer aluminum shell with an internal stainless steel screen that can protect the components from environmental contamination, and can also keep contaminant like rust from being ejected at high speed into the work area. They have a typical noise reduction of 14 dB.

Pneumatic Valves:

  • Manual Valves allow for operators to turn on and off their system by hand. The full-flow ball valves range from ¼” NPT to 1 1/4” NPT in size and will not restrict flow.  EXAIR also offers a manual foot pedal valve for hands-free operations.  This ¼” NPT foot valve has a 3-way operation and works great if the operator has to use both hands in their process.
  • Solenoid Valves are a way to turn on and off the supply of compressed air electrically for automated systems. We offer solenoids in three different voltages; 110Vac, 240Vac, and 24Vdc.  EXAIR has a large range of flows with ports ranging from ¼” NPT to 1” NPT.  All models are UL listed and are CE and RoHS compliant.

Hardware:

EXAIR’s Swivel Fitting Family

  • Swivel Fittings are a great way to securely install and aim EXAIR nozzles. They are dynamic as they can be adjusted and set to a flow direction with 50-degrees of movement.  They are made from 303SS or 316SS for corrosion resistance with ports ranging from 4mm to 1” NPT.
  • Compressed Air Fittings are a nice arrangement to connect different compressed air items together. We offer a range of hex and close nipples, couplings, reducers, tees, elbows, crosses and bulk head fittings.  If you need a quick way to connect directly to your pneumatic system, we may have it on the shelf.

    Model 9043
  • Magnetic Bases are designed for a solid mount to steel surfaces and for easy portability of your blow-off system to different locations. It has a 100 lb. (45.5Kg) pulling force to keep the blowing device attached firmly until you want to move it.  They can be mounted in a vertical or horizontal position.  EXAIR offers a single outlet Magnetic Base (for one blow-off device); a dual outlet Magnetic Base (for multiple blowing products); and a single outlet Swivel Magnetic Base (to offer more flexibility to orientation).  The bases come with a ¼ turn shut-off valve to easily turn on and off the compressed air to the EXAIR products.
  • Receiver Tanks are used to store compressed air. They can be used at the air compressor or as secondary reservoirs for intermittent demand.  They help your compressed air system with pressure variations and high demand loads.  EXAIR offers a model 9500-60 Receiver Tank that has a 60 gallon capacity and is rated to 200 PSIG.  It meets the ASME pressure vessel code.

    Universal Air Mounting Kit
  • Universal Air Knife Mounting System gives you a way to mount the EXAIR Super Air Knife, Full-Flow Air Knife, and Standard Air Knife. This kit is used to position your air knife securely and precisely.  It comes with a bracket and an articulated arm that can reach up to 30” (762mm).  You can orientate the air knives in any position to maximize the effectiveness.

    Plumbing Kits
  • Plumbing Kit, or PKI, is a great tool for longer Super Air Knives to help attach your compressed air system. They are designed to help lessen the time for install as well as to properly supply compressed air equally along the entire length, specifically for 24” (610mm) and longer.  We can offer the Plumbing Kit separately if you find that it could benefit your fabricators during installation.
  • Coupling Kits are designed to attach Aluminum and Stainless Steel Super Air Knives if you need to extend past the 108” (2,743 mm) width. Coupling Kits will mount the air knives together end to end.

Hoses:

  • Conveying Hoses are used with our Air Operated Conveyors or Line Vacs. The hoses are made from a durable PVC semi-flexible hose with six different diameters from ¾” I.D. up to 3” I.D.  The conveyance hoses can slip easily to the ends of the Line Vacs or to tubes for an easy transition.  EXAIR can cut-to-length Conveying Hoses up to 50 feet (15m); in increments of 10 feet (3m).
  • Coiled Hoses get compressed air from the piping system to the EXAIR product. They are made of a durable abrasion-resistant nylon material that is 12 feet long (3.6 meters).  They have swivel fittings at the end to allow for easy uncoiling, and a spring strain relief to keep the hose from kinking.  The coiled design makes it easy to reach around the work area and retract back to the substation.  This will help to keep the hose off the ground where potential dangers could occur.  We offer 3 different connection sizes; 1/8” NPT, ¼” NPT, and 3/8” NPT.
  • Compressed Air Hoses is another way to supply EXAIR products. They are useful if you need to reach from overhead sources or around equipment.   They are made from a reinforced synthetic rubber in 3/8” I.D. and 1/2” I.D. diameters.  We can make specific lengths up to 50 feet (15m).  They are rated for 250 PSIG (17 bar) air pressure, and the hose material works well for long-lasting protection against ozone, weathering and temperatures up to 158oF (70oC).  They come standard with two male ends in ¼” NPT or ½” NPT.
  • Stay Set Hoses give you that possibility of manually adjusting or re-adjusting Super Air Nozzles. The hose has a “memory” function; so, it will not creep or droop until you physically move it.  They work well to direct air flows in unique ways at specific target areas.  They can be used with Super Air Nozzles, Safety Air Guns and Blow-off Kits.  The Stay Set Hoses come in lengths from 6” (15cm) to 36” (91cm), and they are offered with ¼” NPT male on both ends or with a 1/8” NPT female and a ¼” NPT male connections.  These hoses are rated for 250 PSIG (17 bar) and are made from reinforced synthetic rubber.

Temperature Accessories:

  • The ETC, or Electronic Temperature Control, is a digital temperature controller with a LED screen for precision monitoring and adjusting temperatures in a Cabinet Cooler System. The controller has easy-to-use buttons to raise or lower the desired internal cabinet temperature.  Once set, the ETC will hold the temperature to +/- 1 oF (+/- 0.5 oC).  The LED displays the internal temperature for continuous monitoring.  The ETC comes complete with the controller and a solenoid valve in two different voltages, 120Vac and 240Vac.
  • The thermostat is a way to control a solenoid valve electrically to turn on/off a Cabinet Cooler System at a set temperature. It is preset at 95°F (35°C), but it can be adjusted to other desired temperatures.  It has an accuracy to hold the set temperature within +/- 2 °F (1 °C).  It can handle voltages from 24V to 240V, AC (50/60 Hz) or DC.  They are UL Recognized and CSA certified.

In today’s fast-paced world, there is a need to get your devices operating correctly and as quickly as possible.  EXAIR Accessories can do that.  Not only will you have confidence, as you are using the items recommended by the EXAIR experts, but you won’t have to worry about your system “squeaking” to a halt.  Like with my brakes above; I was happy to use the recommended grease to end any annoyance with my braking.  If you would like to discuss the proper options with your EXAIR products, an Application Engineer will be happy to help you.

Magnetic Bases and Stay Set Hoses: Adding Flexibility to EXAIR Products

EXAIR manufactures a variety of intelligent compressed air products that can cool, clean, coat, convey, and conserve.  They’re designed specifically with enhanced efficiencies, OSHA safety, and high quality in mind.  What could make them perform even better?  Making them movable!  EXAIR offers Magnetic Bases and Stay Set Hoses to achieve this.  In this blog, I will cover the features and benefits of both products.

Stay Set Hoses:

The Stay Set Hose gives you that possibility of manually adjusting and re-adjusting smaller EXAIR products like Super Air Nozzles and Air Jets.  The hose has a “memory” function, and it will not creep or droop until you physically move it.  They work very well in directing the air flows at specific target areas.

The Stay Set Hoses come in lengths from 6” (15cm) to 36” (91cm), and they have threaded connections with either ¼” NPT male on both ends or with a 1/8” NPT female and a ¼” NPT male types.

The hoses are made from reinforced synthetic rubber and have a pressure rating of 250 PSIG (17 bar).  They can add versatility to our Safety Air Guns and Blowoff Stations.  If you need positioning for precise blowing or adjustments for different targets, the  Stay Set Hoses would be a nice addition to include with your EXAIR products.

Magnetic Bases:

If you need a solid mount to steel surfaces or to move your blow-off system to different locations, the Magnetic Base will allow you to do these functions.  It has a 100 lb. (45.5Kg) pulling force to keep the blowing device attached firmly until you want to move it.  They can be mounted in a vertical or horizontal position.

EXAIR offers a single outlet Magnetic Base or a dual outlet Magnetic Base (for multiple blowing products). We also have a Magnetic Base with a swivel to help angle the blowing force.  The bases come with a ¼ turn shut-off valve to easily turn on and off the compressed air to the EXAIR products.

If you want to combine the Stay Set Hoses and Magnetic Bases with your EXAIR Air Nozzles and Air Jets, we can create this with the EXAIR Blowoff System.  We can combine multiple devices into a single model number.  At EXAIR, we pride ourselves with great customer service and an “easy to do business” philosophy.  You can contact a friendly Application Engineer to build an efficient, safe, and movable system just for you.
