Adjustable Air Amplifiers Aren’t Just About Adjustability

Adjustability is a key feature for a great many devices:

  • An adjustable wrench – or as I like to call it, the trusty “all 16ths” – is my go-to for work around the house involving anything with a hex…fittings under the sink when I’m cleaning out a drain, nuts & bolts on furniture or household items needing some tightening (or loosening,) etc.  I don’t get out my combination-end wrenches for much except automobile maintenance.
  • Speaking of sinks, my kitchen faucet lets me adjust water flow (and temperature) which is important because I use different flow rates (and temperatures) if I’m getting a tablespoon of water, or if I’m rinsing my hands, or if I’m filling the sink to do dishes.
  • Speaking of tablespoons, I’ve even got an adjustable measuring spoon that lets me get a full tablespoon, a half a teaspoon, or anywhere in between, by moving a lever block back & forth in the spoon head.

Adjustability is a key feature for several EXAIR Intelligent Compressed Air Products too…like our Adjustable Air Amplifiers.  The ‘adjustable’ part has to do with setting the air flow:

Just loosen the locking ring, and you can thread the plug out of, or in to, the body to increase, or decrease the flow and force of the developed flow.  There’s a hole in the plug (opposite the “EXAIR.com” stamp) so you can use a spanner wrench (another adjustable tool!) to thread the plug in or out.

You can get an amazing range of flow from a little twist*:

These are the performance values for a Model 6042 2″ Aluminum Adjustable Air Amplifier with a compressed air supply pressure of 80psig. Regulating the pressure can give you even lower…or higher…flows.                                              *0.002″ to 0.010″ is about 1/4 turn of the plug.

A gap of about 0.010″ is about the max for 80psig supply pressure.  Above that, the air flow overwhelms the Coanda profile, creating a turbulent ‘storm’ in the throat, hampering the efficiency and effectiveness.  The proper “adjustment” for that is to select the next larger Air Amplifier!

While the range of air flow is certainly impressive, their versatility is another major factor in their selection.  I reviewed our Application Database (registration required) for real-life details on Adjustable Air Amplifiers “in the field” and found a litany of other benefits that made them better suited to particular installations than a Super Air Amplifier:

  • A customer who builds automated equipment incorporates the Model 6031 1-1/4″ SS Adjustable Air Amplifier to blow open bags with a puff of air as they move into position on an automated filling machine. They use it because it’s available in stainless steel construction, and it’s still compact & lightweight.
  • A mattress manufacturer uses Model 6043 3″ Aluminum Adjustable Air Amplifiers to  cool mattress springs.  They’re lightweight, the perfect size to match the springs’ profile, and they can “dial them out” for high heat removal before putting springs on a rubber conveyor.
  • A tier 1 automotive supplier has Model 6234 4″ SS Adjustable Air Amplifier Kits installed on their robotic paint line to blow off moisture from parts to prevent water spotting between the wash cycle and the oven.  They use them because the stainless steel construction holds up to high heat due to the proximity to the ovens.
  • A food plant uses Model 6031 1-1/4″ SS Adjustable Air Amplifiers to improve the drying time of 3,000 liter mixers that must be washed between batches of different products.  The stainless steel construction holds up to the rigors of the frequent washdown in this area.
  • A bedding manufacturer replaced a regenerative blower with a Model 6041 1-1/4″ Aluminum Adjustable Air Amplifier for trim removal on stitched fabric at bedding manufacturer.  The blower was prone to failure from lint & dust; the Air Amplifier, with no moving parts, is not.  It’s also compact, lightweight, and virtually maintenance free.
  • A light bulb manufacturer installed Model 6030 3/4″ SS Adjustable Air Amplifiers on the ends of open pipes that were used to cool mercury lamp wicks.  This reduced noise levels significantly while providing the same cooling rate, and the stainless steel construction holds up to the heat of the operation.

Because of the simplicity of their design, Adjustable Air Amplifiers are also extremely adaptable to custom applications.  We’ve added threads or flanges to the inlets and outlets of several different sizes, to accommodate ease of mounting & installation:

Among other custom Air Amplifiers, we’ve put (left to right) threads on the outlet, ANSI flanges on the inlet/outlet, Sanitary flanges on the inlet/outlet, and Sanitary on the inlet/ANSI on the outlet. How are you installing your Air Amplifier?

Adjustable Air Amplifiers are available in both aluminum and 303SS construction, to meet most any environmental requirements…except extreme high heat.  In those cases, the Model 121021 High Temperature Air Amplifier is rated to 700°F (374°C) – significantly higher than the Aluminum – 275°F (135°C) or the Stainless Steel – 400°F (204°C).  They’re commonly used to circulate hot air inside furnaces, ovens, refractories, etc.

A Model 121021 1-1/4″ High Temp Air Amplifier directs hot air to a rotational mold cavity for uniform wall thickness of the plastic part.

Adjustability.  Versatility.  Durability.  If you’d like to know more about the Adjustable Air Amplifier, or any of EXAIR’s Intelligent Compressed Air Products, give me a call.

Super Air Nozzles and Stay Set Hoses to Replace Open Tubes

I recently worked with an company that performs energy audits and they were working with a food company to review and propose ways to reduce the energy consumption throughout the plant. One area where we were able to help was on an onion peeling machine, shown below:

Vegetable Peeler Wide
Onion Peeler With Screw Conveyor and Blow off Tubes

The area of machine in question used a screw conveyor and friction source to help loosen the peels and fifteen (15) 1/4″ O.D. open ended tubes, which were noisy and unsafe, to blow the peels completely off and away form the onion. The auditor was able to install an air flow meter on the system and found that the machine was consuming 220 SCFM of compressed air for this operation.

Vegetable Peeler Detail
(15) Total, 1/4″ Tubes Used to Blow Air and Help Remove the Peels

We proposed to replace the tubes with a 6″ Stay Set Hose and the model 1103 Mini Super Air Nozzle.  Each model 1103 Mini Super Air Nozzle will consume just 10 SCFM of 80 PSIG compressed air. Attached to the 6″ Stay Set Hose, the nozzle can be placed exactly where needed and aimed appropriately. A strong blast of air rated at 0.56 lbs (9 ozs.), and ultra quiet at 71 dBA, the Mini Super Air Nozzle delivers the results needed.

Model 1103 – Mini Super Air Nozzle

1103 Performance

1103 Pattern

9256
Model 9256 6″ Stay Set Hose

The Stay Set Hose has “memory” and will not creep or bend, simply install the 1/4 NPT fitting into the compressed air supply side, an thread the 1/8 NPT Mini Super Air Nozzle into the other end and position as needed!

Fifteen (15) of the Mini Super Air Nozzles will pass 150 SCFM of compressed air compared to the current usage of 220 SCFM, resulting in a 70 SCFM drop, or a 31.8 % reduction.  At a typical cost of $0.25 per 1000 Cubic Feet of Compressed Air, the nozzles would save $1.05 per hour of operation. Rate of Return yields a full pay-off in just 43 days of operation (24 hours per day operation)!

If you are looking for ways to save on compressed air usage in your facility that is safe to operate and quiet to use, we will have a solution for you.

If you have questions about any of the 16 different EXAIR Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

What’s In My Air, And Why Is It Important?

Everyone knows there’s oxygen in our air – if there wasn’t oxygen in the air you’re breathing right now, reading this blog would be the least of your concerns. Most people know that oxygen, in fact, makes up about 20% of the earth’s atmosphere at sea level, and that almost all the rest is nitrogen. There’s an impressive list of other gases in the air we breathe, but what’s more impressive (to me, anyway) is the technology behind the instrumentation needed to measure some of these values:

Reference: CRC Handbook of Chemistry and Physics, edited by David R. Lide, 1997.

We can consider, for practical purposes, that air is made up of five gases: nitrogen, oxygen, argon, carbon dioxide, and water vapor (more on that in a minute.)  The other gases are so low in concentration that there is over 10 times as much carbon dioxide as all the others below it, combined.

About the water vapor: because it’s a variable, this table omits it, water vapor generally makes up 1-3% of atmospheric air, by volume, and can be as high as 5%.  Which means that, even on a ‘dry’ day, it pushes argon out of the #3 slot.

There are numerous reasons why the volumetric concentrations of these gases are important.  If oxygen level drops in the air we’re breathing, human activity is impaired.  Exhaustion without physical exertion will occur at 12-15%.  Your lips turn blue at 10%.  Exposure to oxygen levels of 8% or below are fatal within minutes.

Likewise, too much of other gases can be bad.  Carbon monoxide, for example, is a lethal poison.  It’ll kill you at concentrations as low as 0.04%…about the normal amount of carbon dioxide in the atmosphere.

For the purposes of this blog, and how the makeup of our air is important to the function of EXAIR Intelligent Compressed Air Products, we’re going to stick with the top three: nitrogen, oxygen, and water vapor.

Any of our products are capable of discharging a fluid, but they’re specifically designed for use with compressed air – in basic grade school science terms, they convert the potential energy of air under compression into kinetic energy in such a way as to entrain a large amount of air from the surrounding environment.  This is important to consider for a couple of reasons:

  • Anything that’s in your compressed air supply is going to get on the part you’re blowing off with that Super Air Nozzle, the material you’re conveying with that Line Vac, or the electronics you’re cooling with that Cabinet Cooler System.  That includes water…which can condense from the water vapor at several points along the way from your compressor’s intake, through its filtration and drying systems, to the discharge from the product itself.
  • Sometimes, a user is interested in blowing a purge gas (commonly nitrogen or argon) –  but unless it’s in a isolated environment (like a closed chamber) purged with the same gas, most of the developed flow will simply be room air.

Another consideration of air make up involves EXAIR Gen4 Static Eliminators.  They work on the Corona discharge principle: a high voltage is applied to a sharp point, and any gas in the vicinity of that point is subject to ionization – loss or gain of electrons in their molecules’ outer valences, resulting in a charged particle.  The charge is positive if they lose an electron, and negative if they gain one.  Of the two gases that make up almost all of our air, oxygen has the lowest ionization energy in its outer valence, making it the easier of the two to ionize.  You can certainly supply a Gen4 Static Eliminator with pure nitrogen if you wish, but the static dissipation rate may be hampered to a finite (although probably very small) degree.

At EXAIR Corporation, we want to be the ones you think of when you think of compressed air.  If you’ve got questions about it, give us a call.

Great Stuff About Jets

There are a number of fascinating facts about jets…both the aircraft engines and the EXAIR Intelligent Compressed Air Products:

  • Because they don’t require dense air to engage spinning blades (like their propeller driven counterparts,) they can operate at much higher altitudes. (Jet aircraft engines only)
  • They provide a high thrust, directed airstream, which makes them great for part ejection, chip removal, and part drying. (EXAIR Air Jets only)
  • With few or no moving parts, they are extremely reliable, durable, and safe. (Both jet aircraft engines and EXAIR Air Jets)
  • They use the Coanda effect (a principle of fluidics whereby a fluid flow tends to attach itself to a nearby surface, and follow that surface regardless of the flow’s initial direction) to do what they do.
    • EXAIR Air Jets use this principle to generate a vacuum in their throat, pulling in a large amount of “free” air from the surround environment, making their use of compressed air very, very efficient.
    • Jet (and propeller driven) aircraft wings employ the Coanda effect to create aerodynamic lift, enabling the plane to fly.

Now, since I’m not a pilot, nor do I particularly like to fly, but I AM a fluid dynamics nerd, the rest of this blog will be about the Air Jets that EXAIR makes.

All of our Air Jet products operate on the same principle…using the Coanda effect (as described above) to generate a high volume air flow while minimizing compressed air consumption:

(1) Compressed air enters and is distributed through an annular ring, and directed towards the discharge via the Coanda effect.
(2) This causes entrainment of surrounding air, both through the throat, and at the discharge.
(3) The total developed flow has tremendous force and velocity, for a minimal consumption of valuable compressed air.(1) Compressed air enters and is distributed through an annular ring, and directed towards the discharge via the Coanda effect.
(2) This causes entrainment of surrounding air, both through the throat, and at the discharge.
(3) The total developed flow has tremendous force and velocity, for a minimal consumption of valuable compressed air.

There are four distinct models of the EXAIR Air Jet:

  • Model 6013 High Velocity Air Jet is made of brass for economy and durability.  The annular ring gap (see 1, above) is fixed by a 0.015″ thick shim.  Performance can be modified by changing to a 0.006″ or 0.009″ thick shim, which come in the Model 6313 Shim Set.
  • Model 6013SS is a Type 303 Stainless Steel version, for higher temperatures – good to 400°F (204°C) – and superior corrosion resistance.
  • Model 6019 Adjustable Air Jet is brass construction, and dimensionally identical to the Model 6103.  Instead of a shim that sets the annular ring gap, though, it has a threaded plug, with a micrometer-style indicator, to “fine tune” the gap.
  • Model 6019SS is the Type 303 Stainless Steel version…fine tuning adjustability, good for high heat and/or corrosive elements.

Four distinct models to meet the needs of your air blowing application.

Is It Safe To Use Compressed Air?

Think about it…compressed air is, by definition, gas under pressure: potential (stored) energy.  This energy is intended to do work, like operation of pneumatic tools, actuation of pneumatic cylinders, debris removal with an air gun or blow off device, and (even though I haven’t done it in a while) my personal favorite:

High pressure compressed air is meticulously made, prepared, and stored to ensure the number of surfaces equals the number of dives.

Uncontrolled, unplanned, or accidental releases of stored energy (regardless of the source) are inherently dangerous, and great care must be taken to guard against such incidents.  This is accomplished, primarily, in three areas:

*Operation.  This might be the most prevalent, because it involves the greatest number of personnel (e.g., everyone) as well as the ways compressed air is used (e.g., all of them.)  It’s also the area where the most involved people (the operators) have the most control:

  • Personal protection.  Don’t even think about operating a compressed air device without eye protection.  Ever.  Hard stop.  Also, if the operation involves flying debris, a full face shield, long sleeves, gloves, etc. might be called for.  Hearing protection may be required as well…keep in mind, even if an engineered device (like any of EXAIR’s Intelligent Compressed Air Products) generates a relatively low sound level, the impingement noise of the air flow hitting the object can reach dangerous levels.
  •  Personnel cleaning is prohibited.  The risk of injury to the eyes, respiratory system, and other parts is just too great to rely on personal protective equipment that’s designed for use while discharging compressed air AWAY from the body.  While this is expressly prohibited in certain situations, OSHA has long recognized it as good practice for all industries.
  • No horseplay.  ’nuff said.  Plenty of better ways to have fun at work.

*Design.  This one usually has the advantage of being traceable to a small number of people, and is also the one that’s most likely to be documented.  This is where it starts…if the system is designed to fail, it doesn’t matter how much care the operators take:

  • Supply lines, fittings, and hoses must be rated for use with compressed air, up to and exceeding the maximum discharge pressure of the air compressor.
  • This goes for any tools, blow off devices, components, etc., serviced by the air system.  The only thing worse than a component failing is a component failing in your hand.
  • Shut off valves should be located as close as practical to point(s) of operation.  This allows you to quickly secure the flow of compressed air to a failed component, hose, etc., and prevent further damage or risk of injury.
  • Hoses shouldn’t be run across the floor, where they can become a trip hazard or subject to damage from stepping on them.   This is a surefire way to find out the value of shut off valves (see above.)

*Product specification.  Or, more simply put, using the right tool for the job.  A broader discussion could include efficiency and performance, but we’ll stay within the confines of safety for the purposes of this blog:

  • Be mindful of dead end pressure.  Blow off devices, especially hand held ones like air guns, are oftentimes fitted with a simple open-end discharge.  If this is pushed into a part of the body, the pressurized air can break the skin and cause an air embolism.  This is a serious injury, and can be fatal if it reaches the heart, lungs, or brain.
    • This is a key consideration to OSHA Standard 1910.242(b), which limits the downstream pressure when compressed air is used for cleaning to 30psi.
    • EXAIR products are compliant with this Standard by design…there’s always a relief path for the air pressure; they can’t be dead ended.

Because the compressed air exits through a series of holes, recessed between a ring of fins, any attempt to block the air flow will simply send it in another direction.

  • Harmful sound levels are a consideration as well.  As stated above, hearing protection is required in many cases, but sound levels can be mitigated through the use of engineered products.  EXAIR Intelligent Compressed Air Products, as a result of their high entrainment, generate a boundary layer of air flow that leads to dramatically lower sound levels than a similar-sized open end blow off device.

The Case For The Flat Super Air Nozzles

What do you think of when someone says “air nozzle?” Is it a crimp or a “crush” on the end of a piece of tubing? Is it a device that attaches to the end of a pipe or a hose? If so, does it have engineered features that focus the stream, amplify the flow (through entrainment, perhaps,) reduce the noise level, or provide an element of safety?

If so…you’re right. Any of the above descriptions, strictly speaking, qualify as an “air nozzle,” in fact, just a plain open-ended pipe or tube meets the criteria. As long as it serves to discharge a stream of air towards a target, it’s an air nozzle.

Even the devices with those efficient, quiet, and safe engineered features come in a variety of styles, types, and models. Consider EXAIR’s product line of Air Nozzles and Jets…we have seventy-two distinct models, in a range of sizes, materials of construction, and performance.  That’s a LOT to choose from, and it doesn’t even take into account the products that can be fitted with different shims that, technically, make them a wholly different nozzle, performance-wise.  Which brings us, dear reader, to the focus of today’s blog: the Flat Super Air Nozzle.

Flat nozzles are not unique to EXAIR…there are dozens of others on the market in a variety of sizes and materials.  What IS unique about EXAIR’s Flat Super Air Nozzles is their performance…

Efficiency: When a competitor’s flat nozzle was replaced with a Model 1122 2″ Flat Super Air Nozzle, consumption was reduced from 31 SCFM to 21.8 SCFM.  Since the nozzle was operated 24/7, this resulted in a savings in compressed air cost of $3.31 per day…meaning the nozzle paid for itself in under three weeks.

EXAIR’s Flat Super Air Nozzles have been blowing away the competition since 2003.

Durability: Both our 1″ and 2″ Flat Super Air Nozzles are available in rugged Zinc Aluminum alloy, or heat & corrosion resistant Type 316 Stainless Steel.

Zinc aluminum models are perfect for general purpose blow offs (left,) while 316SS models are specified for food/pharma and high heat or corrosive environments (right.)

Versatility: A 0.015″ thick shim is installed in the Flat Super Air Nozzles.  These provide optimal performance in a wide variety of typical industrial and commercial blow off applications.  We also offer High Power versions, with a 0.025″ thick shim, for additional flow and force.  You can also experiment with other shims, from 0.005″ to 0.030″ in thickness, for customized applications.  These shims are all 316SS, and are available in sets, or individually.  The patented design of these shims, in fact, is key to their high efficiency, as explained in this video:

Ingenuity: While this EXAIR characteristic is not specific to the Flat Super Air Nozzles, our most recent ingenious development features them: the Super Air Scraper.  By combining a scraping blade with the 2″ Flat Super Air Nozzle, we’ve turned our very popular Soft Grip Safety Air Gun into the perfect tool for easy removal of sticky or stubborn debris from most any flat surface.

Scrape off, and blow away, stubborn debris with the Model 1244-48 Soft Grip Super Air Scraper.

EXAIR Flat Super Air Nozzles are Intelligent Compressed Air Products with a 15 year history of successfully solving all kinds of air blowing applications.  To find out more about how they can work for you, give me a call.

Accessories and the Value Added

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:

Clockwise from top: Universal Air Knife Mounting System, Stay Set Hoses, Cabinet Cooler Side Mount Kit, Mounting Brackets for Line Vac, Filter Separator, and Pressure Regulator, Swivel Fitting for Super Air Nozzle, Tool Holder for Industrial Vacuum Drums, Spray Nozzle Mounting Clip.

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:

From left to right: Super Air Amplifier, Super Air Knife, 1″ Flat Super Air Nozzle, High Velocity Air Jets, and Air Wipe all feature replaceable shims to modify performance.

In addition to these product-specific accessories, EXAIR carries a complete line of:

Filter Separators are rated for air flow up to 400 SCFM; Oil Removal Filters, up to 310 SCFM.

*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.

*Mounting Brackets and Modular Coupling Kits for our Filters and Regulators.  The latter are especially handy for easy, compact, and leak free installation.

*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.

*We have manual ball valves (1/4 NPT to 1-1/4 NPT) and Solenoid Valves (120VAC, 240VAC or 24VDC) from 1/4 NPT to 1 NPT, and a Foot Valve, for hands-free operation.

*Swivel Fittings to securely install & aim many of our nozzles, from the Atto to the High Force 1 NPT Super Air Nozzles.  For a little more flexibility, Stay Set Hoses and Magnetic Bases can be used for Air Amplifiers, Super Air Nozzles, and even short Air Knives.

*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.
