EXAIR Accessories – We’ve Got you Covered

When you work with us here at EXAIR, we strive to have all the ancillary items that you might need to make your installation a success, without having to find components at the last minute or perhaps using the wrong sized components. Each specific product line such as Super Air Knives or Line Vac air operated conveyors have specific accessories such as mounting brackets or plumbing kits which EXAIR has made to simplify the installation of those particular products. We also carry generalized accessories which work across all of the product lines so you do not have to use multiple vendors or purchase orders.

Silencing Mufflers – Per OSHA Standard 1910.95(a), a worker must not be exposed to sounds levels above 90 dBA for any eight hour shift of a 40 hour work week.  EXAIR offers several types of mufflers including – Reclassifying, Sintered Bronze, Straight-Through and Heavy Duty.  For reducing the noise associated with an EXAIR E-Vac Generator, Vortex Tube, Cabinet Cooler System, or the exhaust air from cylinders, valves and other air powered equipment, we’ve got a muffler that will help to keep the noise level at an acceptable level.

Mufflers

Solenoid and Manual Valves – The easiest way to reduce compressed air usage and save on operating expense is to turn off the compressed air to a device when it isn’t needed. EXAIR carries a wide assortment of solenoid valves, with offerings in the NEMA 4/4X classification, and supply voltages of 24VDC, 120VAC, and 240VAC.  We also have manual ball valves from 1/4 NPT to 1-1/4 NPT and a foot operated valve, with 1/4 NPT connections.

Valves

Swivel Fittings, Stay Set Hoses and Magnetic Bases – To provide a great degree of flexibility for positioning an EXAIR Super Air Nozzle, Air Jets or Air Amplifiers, EXAIR offers several items.  The Swivel Fittings have 25 degree of movement from the center axis, providing a total of 50 degree of adjustability.  The position is locked in place and holds until adjustment is needed. For applications where frequent re-positioning of the air device is required, the Stay Set Hoses are ideal.  Simply mount the hose close to the application, bend it to the shape preferred, and because the hose has “memory”, it will not creep or bend.  Lastly, the Magnetic Bases are another option for flexible, movable installations.  The base has a on/off valve, and a powerful magnet to hold in any vertical or horizontal mounting arrangement.

Hoses – EXAIR can provide hoses for your application.  For the Line Vac air operated conveyor applications, we offer conveyance hose – a durable, clear reinforced PVC hose, in diameters of 3/8″ to 3″ ID, and lengths up to 50′. On the compressed air side, we can provide 12′ Coiled Hoses with 1/8, 1/4, and 3/8 NPT connections, and also 3/8″ and 1/2″ ID hose in lengths to 50′.

Hoses

Filter Separators, Oil Removal Filters and Pressure Regulators – Perhaps the most important accessories for use on a compressed air device are filters and regulators. Filtering the compressed air of dirt, debris, moisture and oil will help to prevent build up inside the EXAIR products, leading to longer service life, and less time spent cleaning, while providing optimum performance. Regulating the air pressure allows for tuning of the performance, using the proper amount of compressed air to obtain satisfactory results.

Super Air Wipe Controls Coating Thickness On Tubing

A large manufacturing company called looking for a better solution to control the thickness of a curing agent being applied to the outside of tubing used in the automotive industry. The tubing is formed in an extruder and travels through a liquid cooling chamber and then air dried. After the tubing is dried, it is sent to a spray chamber where the curing agent is applied to the exterior. On the exit side of the spray chamber, the customer had installed several flexible air lines placed around the perimeter of the tubing to blow air across the surface to help control the coating thickness. This worked somewhat but they were seeing an increase in the amount of rejected material as the air pattern was sporadic and uneven, which caused streaking and dry spots in certain areas of the tubing. They reviewed our web site and familiarized themselves with our Air Wipes but were unsure of the best design and size to fit their need so they reached out for assistance.

After further discussing the process, their tube O.D. sizes range from 3/8″ – 1/2″, making our 1″ Air Wipe the ideal solution. As far as the design, the Standard or Super Air Wipe, I recommended they use our Model # 2451 Super Air Wipe kit due to the aluminum construction and stainless steel wired braided hoses being able to withstand the potential temperature in the area of 200°F. The kit includes a filter separator to remove any water or contaminants in the supply and a pressure regulator which would allow them to control the flow and force of the exiting air, to help “dial” it in to fit the demand of the application.

Super Air Wipe is available in sizes from 1/2″ up to 11″ in Aluminum construction and up to 4″ in Stainless Steel construction.

 

EXAIR Air Wipes features a split design, which can easily be clamped around the material, to provide a 360° uniform airflow, perfect for treating the surface of round shapes, like extruded tubing. If you have an application where you are needing to dry, cool or clean the outside of a pipe, hose or cable, contact an application engineer for help making the best product selection.

Oil And Water Don’t Mix, But Oil And Air Sure Do

Do you have oil in your compressed air system? It may be there on purpose…air operated tools require it, and there are a number of devices on the market that provide a precise amount of oil to keep the moving parts in these tools well lubricated and properly operating.

If it’s not there on purpose, it’s not necessarily a problem, though, and it’s hardly uncommon. Many air compressors are oil lubricated, which means there’s oil being pumped at a constant rate, directly towards the piston rings, and a little bit is always going to end up in the air. As the rings wear, even more makes it past…this is impossible to prevent, but, with proper maintenance, it’s kept to a very minimal amount. There are, of course, oil-less compressor designs, which can eliminate this entirely, but they’ve been known to carry a little heavier price tag. Some situations, though, make them worth every penny.

Trace amounts of oil like this don’t affect a lot of compressed air applications, including the performance of most of our products. There are times, however, when oil needs to be addressed…for instance:

*Blow off prior to painting or coating. Even trace amounts of oil on a surface to be painted can cause big problems.
*Electrical enclosure cooling. Oil won’t affect the heat removal performance of an EXAIR Cabinet Cooler System, but it can indeed cause serious issues with electrical/electronic components and devices if it’s present in the cold air that’s blowing on them.
*Air operated conveyors. Likewise, oil won’t hurt the performance of a Line Vac, but keep in mind that anything in the air supply will get on the material or product you’re conveying.
*Static Eliminators. Here’s a situation where oil in the air WILL have an effect on product performance…the emitter points of your EXAIR Static Eliminator need to be kept clean (including oil free) for proper operation. And, again, anything in your air is going to get onto your product.

This is where proper filtration comes in: properly installed downstream of a Filter Separator, EXAIR’s coalescing Oil Removal Filters take out even trace amounts of oil from the air flow, ensuring your process doesn’t see anything but clean, dry air.

Compressed Air Accessories – Filters and Regulators – The Rest of the Solution

IMG_5696

EXAIR Regulator with gauge and Filter/Separator

Many times in the stories that are written in our daily blogs, we espouse the many benefits of installing and using EXAIR made products into our many customers’ compressed air-based applications. From the guy who has a small shop in his home garage using our Atto Super Air Nozzle to much larger applications where customers use our 84” Long Super Air Knives to do such things as drying cast Acrylic Sheets used in tub and shower surrounds, the message is a very consistent one. Customers benefit by saving money, increasing the safety level of an application, reducing sound levels and improving productivity.  There’s no doubt that our customers will excel in these areas.

Knowing there is much more to a compressed air system than just point of use products, lets shed a little light on the other “parts” of a typical system set-up. Those would be the compressed air filter / separators and the pressure regulators that are a highly recommended part of a good installation. But why are they so highly recommended? What exactly is their role and why would anyone want or need to install them?

First, the blunt realities of compressed air and its relative “un-clean” condition once it arrives at the point of use. Since compressed air a utility that is produced in-house, the quality and quantity available will vary widely from facility to facility. And since it is not a regulated utility such as gas or electricity are, there are no universal minimums of quality that compressed air must meet before sent out to the distribution system. Yes, of course, companies are all the time getting better at this part, but many still operate with older, iron pipe systems that produce rust and scale which wreak havoc on the components within mechanical products that use compressed air as their power source. The point is that you are never sure of the quality of the air you will get at the point of use, so install a compressed air filter near that point to keep the debris out of your Air Knife, Nozzle, Line Vac or even other components like solenoid valves, air motors and the like. Believe me when I say it is much easier to un-screw a bowl from a filter housing and change an element than it is to disassemble an air motor or an 84” long Super Air Knife because rust migrated in from the pipes. So it is quite safe to say that an ounce of prevention in this case is worth a pound of cure!

Second, the discussion turns to the Regulator part of the equation. As many know, our products and those of other pneumatic product manufacturers have a certain set of specifications regarding performance at stated input pressures. But what if your application doesn’t require that “full, rated performance”? Maybe instead of needing two pounds of force, you only need one pound? In fact, if you provided two pounds of blowing force, you would end up “over-blowing” your target. By that, I mean you cause damage to the target or other surrounding items in the application. Or, perhaps blowing to hard (or sucking too hard in the case of a Line Vac or E-vac) might cause the vessel or the material you are picking up to collapse or deform (due to too much power).  There is also the concern about using more energy than one really needs to in order to achieve the desired effect in an application. In other words, if you can achieve your goals with only 40 PSIG, then why would you ever use 80 PSIG to accomplish the goal? By reducing your compressed air from 80 down to 40 PSIG, you can easily reduce the air consumption of the “engineered” solution by another 40% + …………that’s the cherry on top of the cake when you compare the benefits of simply “bolting on” the solution of an engineered air nozzle vs. an open pipe in the first place. Then there is the issue of taking advantage of the pressure differential (from 80 down to 40 PSIG) that creates a little bit more air volume capacity. At 80 PSIG, your compressed air to free air volume ratio is 6.4:1. At 40 PSIG, it is only 3.7:1. The net effect is you effectively have an overall larger volume of air at the disposal of the application which is always a good thing.

Regulating pressure is definitely warranted given the benefits that compliment the operation of the core EXAIR products.

If you need a deeper understanding about how EXAIR’s products can help your application, feel free to contact us and we will do our best to give you a clear understanding of all the benefits that can be had by our products’ use as well as proper implementation of accessory items such as compressed air filters and regulators.

Spending Some Extra Time Can Save Money (and Stress)

If you are familiar with our blog, you will see where I have recently written about coaching my oldest son’s pee wee football team this year. Things slowed down this past week as the team had a bye so that meant a “free” weekend or as my wife called it – “a chance to do some of the things you have put off over the last few months”. On the top of the list was painting our bedroom.

painting

Not my idea of a fun weekend!

My oldest son loves to help with projects and I never want to discourage him so when he asked if he could help, of course the answer was “yes”. Not only did this mean I had to spend some extra $ to get some supplies “for kids”, as he put it, I also needed to spend some time explaining what he needed to do. As we started to prep the walls, I went ahead and cut in around the ceiling, doors, baseboard and trim. My plan was that I would paint the top portion of the wall while he worked on the lower. I set up his little roller and watched him paint about a 4 foot wide section and much to my surprise he did a pretty good job. My wife needed a hand with our infant son, so I felt somewhat confident leaving our oldest unsupervised for a few minutes. BIG mistake!

When I got back upstairs, he had painted over the baseboard, trim and managed to drip paint all over the hardwood floors. When I asked him what happened, he responded with “well dad, I wanted to hurry because it’s really nice outside and I NEED to go out and play! Besides you said you were going to have to clean up anyway”. Go outside son, PLEASE, go outside and play. Now not only did I have to clean up the paint, but I also had to spend more money on new baseboard and trim because there is no way I was going to be able to salvage his masterpiece. Maybe I should have spent a little while longer explaining the process? Regardless, my next few moments of “free” time have all been filled.

Taking the time to review your compressed air system can be very important to your company’s efficiency. In many industrial settings/facilities, the compressed air system is an opportunity for savings and efficiency. In fact, the largest motor in a plant is often on the compressor itself. Leaving a small compressed air leak unattended or using an inefficient blowoff for a long period of time can result in very expensive electrical waste. This excessive expense and waste can negatively affect a company’s profit margin as well as reduce performance and increase production costs.

Luckily, EXAIR can help optimize your compressed air system by using our 6 Simple Steps:

6 steps

Measure the compressed air usage using a flow meter. Once you have identified your usage, you can work on finding a more efficient alternative.

Use a leak detector to locate expensive, wasteful leaks.

Replace the inefficient sources with a more efficient engineered solution

Operate the compressed air only when it’s needed. Our Electronic Flow Control (EFC) is an ideal choice to use for on/off service or to set up on a timed basis.

Install a Receiver Tank to provide additional compressed air supply for applications requiring large amounts of compressed air.

Control the supply pressure to the device using a regulator. Sometimes operating at lower pressure can still be effective and can reduce the overall energy cost of the operation. 

While I can’t recommend my son to lend (2) little helping hands, I might be able to provide some assistance with optimizing your compressed air system. Give us a call at 800-903-9247 to see how we can help.

How Much Compressed Air Can YOU Save?

I had the pleasure of speaking with a service technician with a pneumatics company recently…he was finishing up a large project for a customer that involved modifying some machinery to reduce compressed air consumption. After the performance of the newly modified machinery was verified, the customer wanted to know how they could be sure they were indeed saving the amount of air that the project engineer estimated that they would save. That’s when he called to ask about EXAIR Digital Flowmeters.

EXAIR Digital Flowmeters are available for iron pipe up to 6", and copper pipe up to 4".

EXAIR Digital Flowmeters are available for iron pipe up to 6″, and copper pipe up to 4″.

If you follow the famous (to EXAIR blog readers, anyway) Six Steps To Optimizing Your Compressed Air System, you know that this is Step #1. So, was it too late to apply a measurement device? Of course not…in this case, the machinery’s original published compressed air consumption rates were used to compare the new actual usage according to the Digital Flowmeter, and it was simple arithmetic from there.  They installed a Model 9095 Digital Flowmeter for 2″ Iron Pipe on the header supplying the machinery, and were not only impressed with the results of the upgrade, but also enjoy the at-a-glance verification of air flow.

Naturally, if you ask for our assistance in the planning stages of a compressed air optimization project, we’ll encourage you to follow the Six Steps in order. Depending on the nature of the problem(s) and the size & complexity of your system, there may be more or less attention paid to certain steps than others.

For instance, a system that was originally equipped with Receiver Tanks at predetermined locations might allow us to skip right over Step #5. If engineered or automated controls, like our EFC Electronic Flow Control & Pressure Regulators are already incorporated, we can check off Steps #4 and #6.

Receiver Tanks are an ideal solution for intermittent demands for high volumes of compressed air.

Regardless of “where” you start with your optimization project, “when” you start should be right now. Leaks and inefficiencies won’t fix themselves. Give us a call, and let’s get started.
