316 Stainless Steel Products- Always in Stock

Metallurgically speaking, stainless steel is a steel alloy with the highest percentage contents of iron, chromium and nickel, with a minimum of 10.5% chromium content by mass, and a maximum of 1.2% of carbon by mass.

Stainless steels are widely regarded for the corrosion resistance that they exhibit. As the chromium content is raised, the corrosion resistance increases as well. The addition of molybdenum also increases the corrosion resistance to reducing acids and against pitting attacks in chloride solutions. By varying the chromium and molybdenum content, different grades of stainless steel are produced with each suited for varying environments. Due to the resistance to corrosion and staining, stainless steel is ideal material for many applications, especially in the food, pharmaceutical, and chemical industries.

The 300 series stainless steels are considered chromium-nickel alloys and is the largest group and most commonly used. Of the different compositions within the 300 series family, Type 304 stainless is the most widely used followed by Type 316, which has 2% molybdenum added to provide greater resistance to acids and to localized corrosion caused by chloride ions.

Table below shows the nominal composition by mass content for 316 stainless steel

Because 316 stainless steel provides a high level of corrosion resistance, resists pitting, and has good strength properties, EXAIR manufactures many of its products from 316 stainless steel material so that they can be used in the harshest of environments.

Of the EXAIR products these are available off the shelf in 316 stainless steel- Super Air Knife, certain sizes of Adjustable Air Amplifiers, numerous Air Nozzles, Line Vacs including the Sanitary Flanged style, NEMA Type 4X and Hazardous Location Cabinet Coolers. If you need one of our other products such as the Super Air Wipes or Vortex Tubes made in 316 stainless steel, just let us know. Of course we also have them made from Type 303 stainless steel, in stock and ready for shipment (and aluminum, too!)

Compressed Air Pressure Regulators Conserve And Protect

Imagine you’re enjoying a nice shower. A cascade of warm water is soothing your body – and spirit – then, someone starts the dishwasher. Or a load of laundry. Or flushes the toilet. Suddenly, the “soothe” turns to “scald” or “freeze,” depending on whether you’ve been robbed of hot, or cold water.  So, what happened?

What happened is, all of those “loads” on your house’s water supply that can ruin your shower experience are controlled by simple on/off valves…they open to permit a certain amount of water FLOW to pass.  When the dishwasher starts, or someone decides to wash a load of whites, the HOT water from your nice warm shower is diverted, leaving a stream of cold water.  When a toilet flushes, or it’s a load of colors, the COLD water is diverted…and that’s not just unpleasant, but downright painful.  Either way, (in my house anyway,) a teenager is getting read the riot act.

The same phenomenon can apply in a compressed air system, if simple flow control valves are used to throttle the appropriate supply of air to a pneumatic device.  If someone, for example, hooks up an air gun to blow off their tools or parts, the valves on EVERYTHING else will need to be opened up some to keep those devices working the same.  In the case of an air gun like this, it usually happens too quick to make the necessary adjustments (by hand) and you’re probably left with a machine tripped off-line, or a ruined part.

Pressure Regulators can prevent this by keeping (or regulating) their downstream pressure to a set value.  If a load elsewhere in the system is activated, the Pressure Regulator opens up, automatically, to keep its output constant.  When that load is secured, the Pressure Regulator closes back down accordingly.  Either way, no single load affects the operation of any others.

That’s only half the value of the use of Pressure Regulators, though.  The other half is, well…the value.  Just looking at a typical function of many EXAIR Intelligent Compressed Air Products – blow off – they’ll all pretty much accomplish the task if you run them, unrestricted, straight off your header.  That’ll give you a good, strong blast of air flow…and it may be more than what’s required, and a waste of good air.  Pressure Regulators will prevent this by allowing you to “dial in” the supply pressure to whatever it takes to get the job done, and no more.

EXAIR offers a range of Pressure Regulators capable of handling air flow of up to 700 SCFM.

Compressed air isn’t free.  Heck, it isn’t even cheap.  Don’t use any more than you have to, and get the most out of what you do use.  Pressure Regulators are one important step in doing this.  If you’d like to talk about optimizing your use of your compressed air system, give me a call.

The Case For EXAIR Swivel Fittings

One of the more common questions we get here in the Application Engineering department at EXAIR is…

“What’s the best angle to position a Super Air Nozzle?”

The simple (and perhaps a little snarky, but I swear that’s not intended) answer is…

“The angle it takes to get the results you need.”

But wait, there’s more…we’re not going to leave anybody hanging like that. Many blow off applications are going to be best served by a “sweep” of air, at a low angle. That will be ideal for removing a light layer of dust from a relatively flat and smooth surface. A bit larger angle, relative to the surface, may be necessary if you need some impingement force to dislodge sticky, clumpy, or mildly adhesive debris.  Rarely will you want to blow directly, at a perpendicular angle, to a material’s surface.  An exception to this might be if you’re trying to remove excess moisture from a porous and thin material, like a web fiber.

Regardless of what angle you need to aim your Super Air Nozzle, there are several ways to do it.  You can use a compression fitting them onto bendable copper tubing…just don’t bend it too much or too often.  We’ve got Stay Set Hoses that allow for quick & easy repositioning…they come in lengths from 6″ to 36″, and are in stock.

EXAIR Stay Set Hoses and Swivel Fittings are ideal for installation and positioning of your Super Air Nozzle.

If you want to hold it in place firmly and securely, you’re looking for a Swivel Fitting.  They’re available for almost all of our Super Air Nozzles, from the Atto to the 1″ NPT Model 1114 High Force Super Air Nozzle.  They offer 50° of total movement, and are made of Stainless Steel for durability in most any environment.

EXAIR Swivel Fittings have male NPT threads on one end, and female NPT on the other.  The smaller Swivels, for the Atto, Pico, and Nano Super Air Nozzles, have M4x0.5mm, M5x0.5mm, and M6x0.75mm female threads, respectively, in the ball of the swivel itself for direct threading of these small Super Air Nozzles.

EXAIR’s Swivel Fitting Family

Swivel Fittings can also be used with a host of other EXAIR products.  In addition to the Super Air Nozzles, for example, they’ve historically been very popular with our Air Amplifiers.  Here’s a short informational video showing just how versatile they are:

EXAIR Intelligent Compressed Air Products are made to be easy to install & operate.  This is our intent from Research & Development, to Shipping & Receiving.  If you have questions, give me a call.  I want you to get the most out of our products!

UL Classified Certification for HazLoc Cabinet Coolers

Although history only records back so far, I am certain (based on my experiences with sharp and heavy objects) that humans have been injuring themselves with tools, and the stuff they make with them, since the beginning of time.  In fact, recorded history DOES bear this out…the famous Code of Hammurabi (circa 1750 B.C.) set specific amounts of compensation for specific injuries, as did laws from all over the ancient world, from the empires of Rome to China.  Since then, we’ve come a long way in regulating safety not only for the worker in the workplace, but in public places, homes, and workplaces where manufactured products are used.

UL LLC (or Underwriters Laboratories, as they were known throughout the 20th Century) is a safety consulting & certification company founded in 1894 by an electrical engineer named William Henry Merrill.  A year earlier, an insurance company hired Merrill to perform a risk assessment and investigation of new potential clients…George Westinghouse and Nikola Tesla, the proprietors of the Palace of Electricity at the 1893 Chicago World’s Fair.  It was this experience that made him realize the potential for such an agency to test and set standards for product safety at the dawn of a new age of technology development.  And 120 years on, the benefits in safety & protection have been proven many times over.

If a product or device carries one of these markings, it’s been evaluated for safety by top professionals in the field.

One of the more critical accreditations that a manufacturer can receive for a product is the UL Classified Mark.  This differs from other markings (like the ones shown above for Certified, Listed, or Recognized) in that Classification means that samples of the product were tested & evaluated with respect to certain properties of the product.

EXAIR’s new Hazardous Location Cabinet Cooler Systems bear the UL Classified Mark.  This means they meet the stringent UL requirements for installation on purged electrical enclosures in specific classified areas:

  • Class I Div 1, Groups A, B, C and D
  • Class II Div 1, Groups E, F and G
  • Class III
EXAIR Hazardous Location Cabinet Cooler Systems maintain NEMA 4/4X Integrity and are CE Compliant.

When choosing products for use in classified areas, it’s critical to ensure safety through compliance, and the HazLoc Cabinet Cooler Systems allow you to do that, with simplicity and reliability.  If you’d like to discuss an enclosure cooling application, in or out of a classified area, give me a call.

Benefits of Atomized Liquid Nozzles vs. Liquid Nozzles

There are a great many applications that require a spray (as opposed to a stream) of liquid. Certain droplet sizes, and flow rates, are beneficial for certain applications. For example, if you’re fighting a fire, you want as high of a flow rate as possible – the more water you douse the fire with, the quicker it goes out.  You also want a fairly large droplet size, since a mist would tend to evaporate instead of extinguishing the flames.

Pressure washers also benefit from higher (though not near as high as fire hose) flow rates, and droplet sizes.  You want an appreciable flow rate, because that means high velocity, and good sized droplets combine that velocity with their relative mass to “blast” away dirt and detritus from the surface.

Medicine delivery devices, like asthma inhalers, are designed to produce mid-sized droplets, but pretty low (and controlled) flows.  The droplets need to be small enough to efficiently spread the medicine through the breathing passages, but large enough to where they won’t evaporate before they ‘plant’ on the nasal & bronchial membranes to get absorbed.

These are examples of “liquid-only” nozzles…no other media or means of force are used to effect the spraying action.  Most of the time, the droplet sizes in these applications are measured in hundreds of microns, which “liquid-only” nozzles are ideally suited to generate.  Other applications, however, call for much smaller droplet sizes…such as those only attainable through atomization.

EXAIR Atomizing Spray Nozzles use compressed air to create a fine mist of liquid, with droplet sizes as low as 22 microns.

A typical “liquid-only” nozzle is capable of producing droplet sizes of 300-4,000 microns. Atomizing Nozzles’ droplet sizes are consistently under 100 microns, and can be as small as 20 microns!

Small droplet size is key to cost effectiveness in many applications:

  • Think about expensive coatings…the smaller the droplet size, the better and more even the coverage, and the less you have to spray (and pay) out.
  • Or humidification…smaller droplet size means more stays airborne, for longer, and in a larger space.
  • Petroleum based lubricants, by their nature, only require a thin layer for best results.  Smaller droplets make as even and thin of a layer as possible.
  • Dust control is much more effective with smaller droplet sizes, since the longer the mist lingers in the air, the more dust particles the individual droplets will adhere to…and then drop with them to the surface.  This also prevents getting the surface of the material any wetter than it has to be.
142 distinct models. 8 different patterns. Liquid flow rates from 0.1 to 303 gallons per hour. If you’ve got a spraying application, EXAIR has an Atomizing Nozzle for you!

If you’d like to discuss a liquid spraying application, I’d love to hear from you.  Call me.

Choosing the Best Chip Vacuum for Your Application

One Christmas, a long time ago, my Mother In Law gave me a beautifully wrapped present, and a great big smile.  I opened it up…it was an extension cord.  One of those heavy duty orange, indoor/outdoor, 100 foot long models.  I returned her smile, while thinking about all the things I might be able to use it for…and not coming up with anything really solid.

As the family continued to open presents, she disappeared into the other room, and came back with a much larger package and handed it to me…still with that great big smile.  It was a convertible string trimmer; one that worked as a ‘weed eater’ or, with a twist of the handle, an edger.  And it was electrically operated…NOW I knew what the extension cord was for.  As great and useful a gift it was – eighteen years on, and I’m almost competent at edging the sidewalk – I got a valuable lesson from it: accessories make a great gift better.  Since then, I’ve always thoughtfully considered:

  • If I give someone a battery operated gift, I give them batteries too.
  • If it comes with its own rechargeable battery, I carefully open the package and charge it up, before I wrap it up.
  • If accessories are available, I think about how they might use it.  I’ve even presented them with the accessory first, in tribute to my wonderful wife’s wonderful Mom.
  • If there’s a “deluxe” or “premium” version, sometimes it’s worth it to just go all out…again, after consideration of how they might use it.

Now, this is not only the case with presents…many household, commercial, or industrial products offer Deluxe or Premium packages…like the EXAIR Chip Vac System.

At the most basic level, a Model 6193 Chip Vac System for 55 Gallon Drum is all you need to turn an existing drum into a powerful, reliable, durable industrial vacuum.  It comes with a lid & latch ring, Filter Bag, 10 foot vacuum hose, a set of plastic tools, and of course, the Chip Vac itself.  All you need for simple, on-the-spot cleanup purposes.

Model 6193-30 is also available for your existing open-top 30 Gallon Drum.

Sometimes you might have (literally) more ground to cover: the Model 6293 Deluxe Chip Vac System adds a Drum Dolly for mobility, and a Tool Holder to keep the attachments handy.

Deluxe Chip Vac Systems come with a Dolly and Tool Holder in 5 Gallon (left,) 30 Gallon (center,) and 55 Gallon (right) sizes.

Other times, you may just be looking for a complete system, ready to handle everything, right out of the box.  Enter the Model 6393 Premium 55 Gallon Chip Vac System, which adds a heavy duty steel drum, an upgrade to Heavy Duty Aluminum Tools & Static Resistant Vacuum Hose, and a 20ft Compressed Air Supply Hose with Pressure Gauge & Shutoff Valve.

Premium Chip Vac Systems are ready for any cleanup job, right out of the box, and come with 30, 55, or 110 Gallon Drums.

Or, if you’re looking for something lightweight & compact, the Model 6193-5 Mini Chip Vac System comes complete with a 5 gallon drum, and the Model 6293-5 Deluxe Mini Chip Vac System adds a Drum Dolly.

The Mini Chip Vac System comes complete with a 5 Gallon Drum, and the Deluxe System adds a Drum Dolly for mobility.

With no moving parts to wear and no electrical components to burn out, the EXAIR Chip Vac is a virtually maintenance free replacement for noisy, damage-prone electric vacuums.  If you’d like to find out just how handy they are, give me a call.

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.
