The pneumatic industry is huge. Almost every manufacturing plant around the world uses compressed air in one way or another. EXAIR has manufactured Intelligent Compressed Air Products since 1983, and in that time we have gathered much information. We sorted this data and placed it in our Knowledge Base section for all to see. Now, if you have a compressed air system in your plant, EXAIR probably has information about usage, optimization, and application details where we were able to solve or improve the settings with cost savings, efficiency, and safety. In this blog, I will cover one section of the Knowledge Base categories; FAQs.
FAQs, or Frequently Asked Questions, is a library of inquiries that our customers have asked in the past. We compiled this collection that end-users, resellers, OEMs and distributors asked; and, we placed them in one area to be found quickly and easily. The FAQ library is located under Knowledge Base (reference photo above). We separated the FAQs by product groups to find more information like maximum temperatures, pressures, viscosities, etc. This in-depth assortment of information can help to swiftly answer some obscure questions that may be important for your application.
As an example, I recently received a call from a customer requesting information about the Reversible Drum Vac. This product is a two-way pump that uses compressed air to transfer liquid in and out of steel drums. They do not have any motors to wear or electricity to work; so, they are very reliably and long-lasting. This pneumatic pump works wonderful for transferring coolants. But this customer wanted to know if it can transfer hydraulic fluids; and if so, how fast. I was able to direct them to our FAQ library. We found that it can pump 10 gallons/minute or 38 liters/minute of hydraulic fluid. They also noticed that the Reversible Drum Vac can pump even more viscous fluids, like 15W40 motor oil. It opened their eyes on the capabilities of the Reversible Drum Vac for other applications in their facility.
Of course, Application Engineers at EXAIR are always available to answer questions about our products or about your applications. But if EXAIR is closed and you want to buy right away, the FAQ section could be a great place to find that “nugget” for a quick answer.
EXAIR prides itself in offering products with high-performance and peak efficiency. All EXAIR products are manufactured to meet the strict requirements of a variety of different standards, ensuring that you receive a reliable, high quality product that WILL perform to the specifications we publish.
Safety is a top priority for most companies, EXAIR’s line of Intelligent Compressed Air Products meet or exceed the strict safety standards set forth by both OSHA and the European Union. EXAIR products comply with OSHA 29 CFR 1910.242(b), the standard implemented to ensure safe operation of compressed air blowoff devices, and the EU General Product Safety Directive (2001/95/EC).
Additionally, they comply with the noise limitation requirements set forth under 29 CFR 1910.95(a) and the EU Machinery Directive (2006/42/EC). From the Optimization product line, EXAIR’s Electronic Flow Control and the Electronic Temperature Control meet the low voltage standards of EU Low Voltage Directive (2006/95/EC). A CE label is placed on all products that comply with applicable directives.
UL, or Underwriters Laboratories, is a third-party safety and consulting organization that certifies products after thorough testing and evaluation. EXAIR’s Cabinet Coolers are UL Listed to US and Canadian safety standards. Static Eliminators are also UL Component Recognized. Within our line of Cabinet Coolers is the Hazardous Location Cabinet Cooler, bearing the Classified UL mark for use in classified areas.
In the assembly of electrical products there can be hazardous materials used during production. The Restriction of Hazardous Substances, also known as RoHS or (2002/95/EC), restricts the use of materials such as: lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and four different phthalates. The electrical portions of EXAIR’s Static Eliminators, Electronic Flow Control, Electronic Temperature Control, Digital Flowmeter, solenoid valves, and thermostats all comply with the amendment outlined in the European Commission decision L 214/65.
In addition to RoHS, EXAIR is also committed to providing products that are conflict mineral free. In support of Section 1502 of the Dodd-Frank Wall Street Reform and Consumer protection Act, EXAIR complies with the conflict minerals rule to curb illicit trade of tin, tantalum, tungsten and gold in the DRC region. Using the CMRT 4.20 template, we’re able to document our supply chain to ensure our materials are not being sourced from places that could finance conflict in the DRC and surrounding countries.
Finally, per Regulation (EC) No 1907/2006 Title I, Article 3, paragraph 3, the European Union enacted legislation requiring substances and chemicals imported into the EU to be registered to ensure a high level of protection for human health and the environment. Per Title II, Article 7, paragraph 1, articles must be registered when a substance is intended to be released during normal conditions of use that would exceed 1 metric ton per producer per year. Since EXAIR products do not contain substances that are intentionally released, registration is not required.
If you’re looking to maintain compliance in your industry, EXAIR products have you covered. If you have any questions about these standards of compliance feel free to reach out to us. Our team of Application Engineers have years of experience in industry are waiting to take your call.
I’m pretty impressed with the number of safety features my car has. Aside from the literal lifesaving functions like seat belts and air bags, it’s got anti-lock brakes…if you’ve ever had to counter-steer out of a skid on an icy road, you will appreciate the value of this for sure. Those are just some of the ones I’m keenly aware of – the Federal Motor Vehicle Safety Standards comprise dozens of regulations in three categories: crash avoidance, crashworthiness, and post-crash survivability. None of these prevent me from operating my vehicle at an unsafe rate of speed…an expensive reality that an Ohio State Highway Patrolman dutifully reminded me of last Sunday afternoon.
Likewise, there are many regulations to ensure safety and prevent hazards of all kinds in industry, administered by a host of agencies that are either subordinates of, or accountable to, the federal government. When you manufacture products that are used with high energy sources (compressed air or high voltage electricity,) a strong commitment to safety is not negotiable. So, at EXAIR, we commit considerable resources towards the best engineering and manufacturing practices to make our products as safe as possible. That includes compliance with a number of standards and certifications:
The Occupational Safety and Health Administration (OSHA) is an agency of the U.S. Department of Labor. Their mission is to “assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance.” They are a regulatory body in the truest sense, in that they don’t offer certification or approval of products, processes, etc.; they publish guidelines and standards for manufacturers and users to comply with. OSHA Standard 1910.242(b), for instance, limits the downstream pressure of a compressed air operated device used for cleaning purposes to 30psi. Now, you can regulate the supply pressure to meet this, but that also limits the effectiveness of the air flow generated. EXAIR Intelligent Compressed Air Products are all designed and manufactured to be in compliance with this standard, at any supply pressure. Take, for example, our Super Air Nozzles:
OSHA also has Standard 1910.95(a), that sets limits for maximum allowable noise exposure. All EXAIR Intelligent Compressed Air Products, with the exception of some our largest and most power Super Air Nozzles (which aren’t normally used in areas that don’t already require hearing protection anyway) meet the 8-hour exposure limits of this standard.
CE marking indicates conformity with health, safety, and environmental protection standards for products sold withing the European Economic Area. Unlike OSHA standards, responsibility for CE marking falls solely with the seller of the product – a CE marked product has been tested and certified to have been made in such a way to meet safety & quality benchmarks specified for that type of product. All EXAIR products that are defined under applicable directives have been tested according to these standards, and carry the CE mark.
The Restriction of Hazardous Substances Directive, or RoHS, is another standard borne from the European Union, and is geared towards public & workplace safety by restricting the use of hazardous materials in the manufacture of electronic & electrical equipment. Since its inception in 2006, similar standards have been vigorously adopted around the globe. Electrical portions of EXAIR’s Static Eliminators, EFC Electronic Flow Controls, ETC Electronic Temperature Controls, Digital Flowmeters, Solenoid Valves, and Thermostats all comply with the RoHS Directive.
Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act doesn’t address a concern for product users, but rather a particularly troubling human rights issue – Conflict Minerals. For almost two decades, trade in tin, tantalum, tungsten and gold in the Democratic Republic of the Congo (DRC) has been used by some very bad people to finance violent campaigns against their neighbors. EXAIR thoroughly and systematically documents our supply chain compliance with this act. We are proudly committed to our support for this effort to the world a better place for everyone…especially those in desperate circumstances beyond their control.
EXAIR Intelligent Compressed Air Products have been successfully implemented into a variety of uses where application- or industry-specific standards are in force. We’re happy to work with you to determine if our products meet those standards…or can be made to meet them. If you’ve got such an application, give me a call.

The word “accessory” can come with some baggage… it’s become synonymous with “add-on” and “up-sell,” and cost-mindful consumers may see them as just another way for a slick salesperson to make an extra buck. And frankly, they wouldn’t have that reputation if there wasn’t some truth to it. The server at your favorite restaurant will offer appetizers, or recommend side dishes to go with your entree. If you go to buy a new car, you’ll get a pitch for a variety of aftermarket add-ons. The paint counter folks at the hardware store always tell me what specific brush and/or rollers I should use with the paint I’m buying…and it’s never the 10-pack of economy brushes that costs less than the single, premium quality brush they recommend. In all of these cases, these employees are trained, constantly encouraged, and hopefully rewarded on the success of these “up-sell” strategies.
Of course, my boys and I can devour even the largest plate of chili cheese nachos long before the rest of meal comes out. My wife absolutely loves the remote starter function that the dealership installed on the new car she bought last year. And, if you’ve ever painted a well-lit room, you know the difference between a $1 paint brush and a $10 paint brush. So if my server gets a little bigger tip, my car dealer salesperson gets a little more commission, or the paint counter folks get a bonus, then it’s a win-win, as far as I’m concerned.
EXAIR carries a variety of accessories for our Intelligent Compressed Air Products. Some aid in mounting & installation:
Others make it easy to ensure adequate supply conditions:
The performance of many EXAIR Intelligent Compressed Air Products can be altered by replacing the shim:
In addition to these product-specific accessories, EXAIR carries a complete line of:
*Filter Separators to remove water, dirt, and rust from your compressed air system. Our Automatic Drain Filter Separators have a 5 micron particulate element, and a centrifugal vane to remove moisture.
*Oil Removal Filters with coalescing elements that remove any trace of oil, and also provide additional particulate filtration to 0.03 microns.
*Pressure Regulators, so you can “dial in” the performance you need, so you don’t overpower the application, or waste compressed air. They come in sizes from 1/4 NPT to 1-1/4 NPT, and are rated for flows up to 700 SCFM. A pressure gauge provides accurate indication of outlet pressure, and the adjustment cap can be removed to prevent tampering.
*Silencing Mufflers to reduce work area noise from compressed air exhausting from pneumatic cylinders, valves, etc. There are several styles to choose from, depending on your needs:
Sintered Bronze Mufflers are simple in design, with minimal back pressure restriction, and come in sizes from #10-32 thread to 1-1/2 NPT.
Straight-Through Mufflers offer noise reduction up to 20 dB, and come in sizes from 1/4 NPT (up to 22 SCFM) to 3/4 NPT (up to 73 SCFM.)
Heavy Duty Mufflers have an internal stainless steel screen that not only protects the exhausting components from environmental contamination, but also keeps air system contaminants from being ejected at high speed into the work area.
Reclassifying Mufflers are an upgrade to the Sintered Bronze Mufflers and provide the highest level of noise reduction – up to 35 dB. They also trap oil mist, eliminating breathing hazards to personnel.
*12 ft Coiled Hoses (1/4″ or 3/8″ ID) and Compressed Air Hose (3/8″ or 1/2″ ID; up to 50ft lengths) can be provided with any Intelligent Compressed Air Product. We also have a full supply of fittings (tees, elbows, nipples, couplers, reducers, etc.) and adapters to fit our Super Air Nozzles to your existing air guns or blow off devices.
*Receiver Tanks are used to store a ready supply of compressed air. If you have an intermittent demand of sufficient size, it can cause a pressure transient in your system, which can drag down the ability to supply other points of use. Installed near the point of intermittent demand, they prevent pressure & volume fluctuations, keeping the operators at all points of use happy. Model 9500-60 Receiver Tank has a capacity of 60 gallons, is rated to 200psig, and meets ASME pressure vessel code.
In closing, let me offer the following advice that’s served me well over the years:
*Be mindful of the valued added by the accessories & add-ons you’re presented during a purchase of capital equipment…or anything else, really. Don’t buy something you don’t need, but if you need it…well…it’s OK to buy it.
*Don’t skimp on quality. Odds are, if an accessory is offered by the manufacturer of the product, it’s going to work well for you. They should be able to tell you if it will or won’t if you discuss your needs with them. I know I will if you call me to discuss a compressed air product application.
*Get the big plate of nachos, especially if you’re dining with teenagers.

Have you ever happened across something that would have been a real “game changer” at some time in the past? I’ll never forget the time that I went camping with my sons’ Boy Scout Troop, and I was introduced to the peanut butter and bacon sandwich. I still enjoy one from time to time, but my doctor does not enjoy hearing about it…
I’ve also written before (and before) about when I found out EXAIR Vortex Tubes were being used in some shipyards for freeze sealing pipes…a task that (when I worked in a shipyard) we used tanks of liquid nitrogen for. I was amazed that such a cumbersome ordeal was replaced by something so simple and easy.
When we were developing the VariBlast Compact Safety Air Gun, a key feature…the variable flow trigger…also would have been real handy at a time in my not-so-distant past. See, I used to run a small industrial equipment service department, and one time I found myself in a pinch to get a structural steel tube frame made for a support for a particular piece of equipment. This wasn’t something we did all the time, and this particular job was a bit larger scale than most of what we’d done before. It wasn’t really a big deal; I just had to cut some rectangular tubing to length with our band saw, drill some small holes (for bolts) and bore some larger holes (for cables & hose) along the length.
We had a small air compressor and a cheap commercial grade air gun, which served the purpose of our infrequent usage. Blowing the shavings away from those holes, and the inside of the tubing was a challenge…that air gun would just barely move them all the way from the holes near the middle, and when I blew out the holes near the ends, the spray of coolant-soaked shavings was making a heck of a mess in our relatively small shop. After a while, I found that I could kind of “mash” the trigger a little to one side and get a rough measure of control…I was only going to have to mop about half the floor, instead of the whole thing, and I wasn’t going to have to wash the service truck parked in the closest garage bay to the shop area.
Needless to say, this wasn’t exactly ergonomic, and it was real pain (literally) to use my left hand for a few days following. Which, being left-handed, was kind of a drag.
Fast forward to just last year, when we rolled out the latest and greatest (in a distinguished line of latest and greatest) EXAIR product: the VariBlast Compact Safety Air Gun. Now, individually, the key features might not be all that mind-blowing to the casual observer, but taken together, they’re a pretty big deal. Consider:
*Aluminum construction – lightweight, durable, corrosion resistant.
*Two compressed air inlets – one on the bottom (below your pinkie finger) and one on the rear (above your thumb;) your choice…whichever makes your task easier.
*Cast-in hanger – to keep it out of the way, but still handy, when you’re not using it.
*Chip Shield – you still have to wear safety glasses, but this will keep them cleaner.
*Variable pull trigger – as the name implies, you can “vary the blast” by how hard (or not) you pull the trigger. Like I said before, you can do this – kind of – with a run of the mill commercial grade air gun, but it’s not very precise, and far from ergonomic. Here’s a short video showing just how sensitive that trigger pull is:
If you’d like to give one a try, EXAIR offers these – and any catalog product for that matter – with a 30 Day Unconditional Guarantee. We invite you to put it through its paces for up to a month. If it’s not going to work out for you, for any reason, we’ll arrange return for full credit. Give me a call – we can talk about how you intend to use it, and which one’s right for you.

Fluidics is an interesting discipline of physics. Air, in particular, can be made to behave quite peculiarly by flowing it across a solid surface. Consider the EXAIR Standard and Full Flow Air Knives:
If you’ve ever used a leaf blower, or rolled down the car window while traveling at highway speed, you’re familiar with the power of a high velocity air flow. Now consider that the Coanda effect can cause such a drastic redirection of this kind of air flow, and that’s a prime example of just how interesting the science of fluidics can be.
As fascinating as all that is, the entrainment of air that these products employ contributes to another principle of fluidics: the creation of a boundary layer. In addition to the Coanda effect causing the fluid to follow the path of the surface it’s flowing past, the flow is also affected in direct proportion to its velocity, and inversely by its viscosity, in the formation of a boundary layer.
This laminar, lower velocity boundary layer travels with the primary air stream as it discharges from the EXAIR products shown above. In addition to amplifying the total developed flow, it also serves to attenuate the sound level of the higher velocity primary air stream. This makes EXAIR Intelligent Compressed Air Products not only as efficient as possible in regard to their use of compressed air, but as quiet as possible as well.
If you’d like to find out more about how the science behind our products can improve your air consumption, give me a call.
