Turn Ordinary Pipe into a Powerful Conveyor w/ EXAIR’s Threaded Line Vac

threaded line vacs

EXAIR’s Line Vacs are the ideal low-cost solution for bulk material transfer. Available with NPT threaded connections, EXAIR’s Threaded Line Vacs allow you to convert ordinary pipe into a powerful conveying system for parts, scrap, trim, and other bulk materials. With performance identical to that of the Standard Line Vac, the Threaded Line Vac is available in sizes ranging from as small as 3/8 NPT and up to 3” NPT there’s a suitable Line Vac for most standard sized NPT pipe common an any industrial facility.

The Threaded Line Vac is available in a range of different materials: Aluminum, Type 303 Stainless Steel, Type 316 Stainless Steel, and as a Heavy Duty conveyor constructed of a proprietary hardened alloy steel for use in abrasive applications. Where most materials would wear out over time, the Heavy Duty Line Vac is the ideal solution for heavy and abrasive materials. In addition to being abrasive resistant, it’s also more powerful and suitable for longer vertical and horizontal transfer distances.

Each style of Threaded Line Vac is also available as a High Temperature option. By replacing the traditional o-rings with graphite seals, we’re able to provide a solution capable of withstanding temperatures up to 900°F!!!

The conveyance rate through the Line Vac is infinitely adjustable by regulating the air pressure supplied to it. At lower pressures, the conveyance rate (and air consumption) will decrease. At higher pressures, the conveyance rate will increase. If you have a Threaded Line Vac with the standard performance but need just a little bit more, the option also exists for a High Power unit that would match the performance of the similarly sized Heavy Duty. This can be ordered from the factory with an “HP” prefix, or modified yourself. Check out our video to see just how simple it is to get more out of your Threaded Line Vac.

With all sizes and materials on the shelf and in stock, we’re able to get a solution out to you quickly. We’ll ship out the very same day for stock orders received by 3:00 ET. Backed by our Unconditional 30 Day Guarantee, you’re able to make sure it is the right solution for you before committing to keep it. If you have an application that could be better served with an in-line pneumatic conveyor, give us a call. We’ll be happy to help you determine the most suitable size for the application.

Unique Nozzle Application Eliminates Procedure for Tobacco Processing Facility

1006ss_3up_500

I recently worked on a unique application for EXAIR’s Back Blow Nozzle. Generally, these products are used to clean out chips, debris, and coolant from the ID of pipes or tubes. With (3) different sizes available to clean out IDs ranging from ¼”-16” it’s the ideal solution for cleaning out pipes where blowing forward into the pipe won’t work. They’re also available on the end of a Safety Air Gun with extensions up to 72” long, allowing you to get to hard to reach areas.

This particular application, however, was slightly different. The customer has a large machine that rotates a large drum to dry the tobacco, much like a standard clothes dryer. Inside of this drum is a “spray boom” with an angled top designed to prevent the tobacco from settling and sticking in large quantities. At the end of this “spray boom” are Atomizing Nozzles used to apply a cleaning solution after each drying process is completed at the end of the shift.  Unfortunately, the angled design didn’t work quite as well as they’d intended.

The customer needed a solution that could periodically clean off the boom while the drying was in operation. It wasn’t reasonable to do this at the end of the drying process once the majority of material had passed through. The accumulated tobacco on the boom was perfectly usable product and anything stuck after the cleaning operation would have to be thrown out as waste. In order to clean the boom and allow the stuck tobacco to remain as usable product, we needed an automated solution.

The customer installed (4) of the 1006SS Back Blow Nozzles situated around the boom to remove any stuck-on product during the drying process. The results spoke for themselves, at 90 PSIG it removed a 14” wide radius of material from the surface. By implementing the Back Blow Nozzle they were able to reduce waste and eliminate a daily 1-hour long cleaning process to remove stuck on material from the boom.

Just because it’s an outside-the-box application for one of our products, doesn’t mean it won’t work!! With EXAIR’s Unconditional 30-Day Guarantee, you can test any of our stock products out before committing to keep them.

UThisThat_LIVEOD_600x150

Not much in life is free anymore. So, make sure and take advantage of EXAIR’s upcoming FREE webinar at 2:00 PM ET on 10/17/2019. Not only are we providing it for free, but in this webinar we’ll be discussing how you can save money by reducing your compressed air consumption. Something for free, that will help save you money? Almost unheard of these days!!! Hosted by one of our highly-trained Application Engineers, Jordan Shouse, you’ll learn about four common ways that you can easily save air in your facility.

Compressed air is often referred to as the fourth utility in industry. When used improperly, compressed air is extremely expensive. Homemade devices such as open-ended and drilled pipes, inefficient air nozzles, leaks, etc. all contribute to increased energy costs. In addition to being wasteful, these devices are not safe and compliant with OSHA standards and regulations. By using an Intelligent Compressed Air Product, you’ll be both saving money and creating a safer environment for your operators.

In this webinar, you’ll gain an understanding of the places in your facility that are wasting the most compressed air. We’ll educate you on the various engineered solutions available from EXAIR to help eliminate unnecessary compressed air usage. You’ll gain the knowledge necessary to determine the best solution based on the application, sound level, compressed air usage, and compliance with OSHA safety requirements. You’ll also learn about the various solutions available to help understand and optimize your compressed air system. You can’t begin implementing a plan to reduce air consumption until you fully understand the usage in your own facility and processes. EXAIR’s line of Optimization products are ideal to help you gain a baseline measurement and begin implementing new products and processes that’ll only help add to your bottom line.

Proper Plumbing Prevents Poor Performance

There’s nothing quite like an ice-cold Coke from McDonald’s. While there’s many reasons for this, one of the reasons for the unique experience of a McDonald’s Coke lies in the straw itself. In their drinks, they provide wider straws that are designed to help enhance the taste of Coca-Cola, or so they claim. Another impact of this is it allows you to drink significantly faster. The wider the opening for liquid to pass through, the more volume you’re able to drink. Imagine trying to drink your Coke, or any other beverage, through a coffee stirrer. I imagine you’re going to have a difficult time and a dry mouth as you try and force what little amount of liquid you can through the small I.D. of a coffee stirrer. Try that with a milkshake and the problems compound…..

The same is true when it comes to plumbing of your point-of-use compressed air products. I recently assisted a customer that was experiencing lackluster performance from the Super Air Knife they purchased. The application was fairly straightforward, they were hoping to reduce the rate of rejected material on their production line of plastic sheets. The sheet goes through a washing process to remove any residual contaminants, then would air dry as it made its way down the line. As the material dried, there were water spots left on the material that would have to then be cleaned off. In the hopes of speeding up the drying process, they purchased a Model 110060 60” Super Air Knife to provide a wide laminar sheet of air to dry the material.

When they hooked everything up, the flow from the knife seemed far less than they were expecting. They were supplying full line pressure (just over 90 PSIG), so in theory they should feel a strong blast of air from the knife. When they installed a pipe tee and pressure gauge directly at the inlet, they noticed the pressure was dropping to 35 PSIG while the knife was in operation. When this occurs, it’s indicative of a lack of volume of air. This can be caused by undersized compressor,  or improper plumbing. In their case, they were only plumbing compressed air to one center inlet of the knife. For a 60” knife, EXAIR recommends a minimum of (4) air inlets to ensure adequate volume.

SAK plumbingh

The size of these lines is also critical. You can’t force greater volumes of air through a smaller hose or pipe, just like you can hardly drink through a coffee stirrer with any great success. A 60” knife requires a supply pipe size of 1-1/2” for up to a 50’ run, if you’re trying to supply a knife of this length with a 100’long, ¼” ID hose, you’re not going to get the performance you expect. If you’re experiencing less than optimal performance from any of your EXAIR Intelligent Compressed Air Products, there’s a good chance air supply is the culprit. The first step is determining what the actual inlet pressure is, install a pipe tee and pressure gauge right at the inlet. Then, give us a call and we’ll help work through the proper line sizes and ensure that you’re getting the most out of our products.

I hope I didn’t make you hungry or thirsty… But I think I know where and what I’m having for lunch 😊!

Air Atomizing Spray Nozzles from EXAIR

EXAIR’s Atomizing Spray Nozzles are used in a variety of applications where atomization of a fluid is necessary. They combine a liquid source and compressed air to atomize the liquid into a very fine mist. With a wide variety of spray patterns and ability to customize the maximum flowrate, there’s an Atomizing Nozzle available for just about any application.

I’d like to take a moment to highlight two particular spray patterns that EXAIR has available: Internal Mix Deflected Flat Fan and Internal Mix 360° Hollow Circular. With both of these particular spray patterns an “internal mix”, the mixing of the compressed air and the liquid will occur inside of the nozzle.

EXAIR PR Hero Images

The Model AD1010SS Internal Mix Deflected Flat Fan Pattern is a ¼ NPT Type 303 stainless steel nozzle designed for applications where mounting space is at a premium. The spray pattern deflects at a right angle to the nozzle’s orientation, allowing the spray to be placed precisely where it’s needed in close quarters. An ideal application for this particular spray pattern is coating the inside of an in enclosure or duct work.

AT5010SSpr_559x

The Internal Mix 360° Hollow Circular Pattern is available in two sizes: ¼ NPT and ½ NPT. These nozzles provide a large 360° circular pattern that works well in applications where a smooth, even coating is needed on the ID of pipe or duct work. Due to the large coverage area (up to 13’ in diameter for Model AT5010SS) they’re also ideal for applications including dust suppression, humidification, and cooling.

Both of these styles of spray patterns are available with or without the No-Drip feature. EXAIR’s patented No Drip Atomizing Nozzles work just the same way as the standard ones, but have the added benefit of positively stopping the liquid flow when compressed air supply is shut off. If your application cannot accept post spray liquid flow dripping onto the product or process, these nozzles are able to accommodate up to 180 cycles per minute with a required 30 PSIG minimum air pressure.

With all sizes and spray patterns available from stock with our Unconditional 30-Day Guarantee there’s no excuse to not give one a try!

Pressure Regulators – Minimize Compressed Air Usage by “Dialing” in Your Air Pressure

In any application necessitating the use of compressed air, pressure should be controlled to minimize the air consumption at the point of use. 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.

SixSteps

Pressure regulators utilize a control knob that is turned to either increase/decrease tension on a spring. The spring puts a load on the diaphragm which separates internal air pressure from the ambient pressure. Typically made of a flexible rubber material, these diaphragms react very quickly to changes in the air supply. By either increasing or decreasing the flow of air based on the load on the diaphragm, downstream pressure remains fairly constant.

Regulator Internal

While one advantage of a pressure regulator is certainly maintaining consistent pressure to your compressed air devices, 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 the pressure to any compressed air operated product.

When selecting a pressure regulator for your application, it’s critical that it is appropriately sized to supply adequate volume to the point of use devices downstream. Doing so, minimizes the risk of experiencing “droop”. Droop is a decrease in outlet pressure from the specified setting due to an increase in flow rate.  Droop occurs when the demand at the point of use exceeds the volume of air that the regulator can supply. By ensuring the pressure regulator is rated to deliver sufficient volume of air, you’ll reduce the chances of experiencing droop. EXAIR offers pressure regulators in kits along with many of our products, we’ve done the hard part for you and made sure they’re properly sized!

If you’re looking for ways to help lessen the demand on your compressor, EXAIR’s team of Application Engineers will be happy to help. Reach out to us via phone, chat, or e-mail and see for yourself just how easy it can be to start saving compressed air!

EXAIR Standard Air Knife Keeps Bottles Free From Contaminants

Recently I worked with a customer on an application to remove contaminants from the inside of glass bottles. During production, dust from the ambient environment was collecting inside of the bottles. They needed a way to remove it prior to filling. The solution was to briefly pause the conveyor, pulsing air into the bottles to free any dust that had accumulated. Their problem was that while the dust was blowing out of the bottle without an issue, some of it was settling back down into the bottles.

P_20190502_123926_vHDR_On

The customer needed a way to mitigate the risk of dust particles resettling into the bottles after it was removed. The solution was to install a Model 2012 12” Standard Air Knife to provide a curtain of air across the top of the bottles, catching any freed dust particles and blowing them away from the conveyor.

After noticing positive results, we wanted to take things one step further and help to reduce overall air consumption in the process. The blowoff was achieved with (8) ¼” open tubes operating at a pressure of 80 PSIG. Although they were only operating for a fraction of a second, they still consume a whopping 33 SCFM! Replacing them with Model 1101 ¼” NPT Super Air Nozzles (14 SCFM at 80 PSIG) resulted in compressed air savings of 58%!!

In addition to saving compressed air, the noise level was also dramatically reduced. At just 74 dBA, we’re below the threshold for an 8-hour exposure time for operators according to OSHA. Where earplugs were necessary before, they’re now able to operate safely without the need for PPE to protect their hearing. The second most effective fundamental method of protecting workers, according to NIOSH, is to substitute or replace the hazard with an engineered solution. It’s not possible to eliminate the hazard as a compressed air blowoff was necessary, but the next best step is to replace it with something safer.

HierarchyControls

In addition to complying with OSHA 1910.95(a), the Super Air Nozzle also cannot be dead-ended. In applications for compressed air blowoff with unsafe nozzles, pipes, or tubes, the pressure must be regulated down to below 30 PSIG according to OSHA 1910.242(b). The installation of an engineered compressed air nozzle by EXAIR allows you to operate safely at much higher pressures.

If you have inefficient blowoff processes in your facility, give one of our Application Engineers a call. We’ll be happy to take a closer look at your application and recommend a safe, reliable, engineered solution!
