EXAIR’s Huge Variety of Air Nozzles is Like an Equalizer for your Application

MCS 3035 Final

Many of us are familiar with what an equalizer (EQ) looks like and what it does. Unfortunately, sometimes they get a bad rap from so-called audiophiles, which in my opinion are defined individuals who spent so much money on their equipment they can’t afford to buy any music to play!  Typically, they insist that tone controls must be set to flat because the sound recording engineers mastering the music have already equalized the recording to perfection and if you need to attenuate or cut certain frequencies it is an indicator of poor-quality equipment, and that is simply is not true!

Let’s consider some of the reasons why an equalizer makes sense and, in my opinion, an absolute necessity. The objects and materials in the room will change the sound reproduction characteristics of any speaker system.  If you have large floor standing speakers positioned in the corners of the room, sitting directly on wood floors the speakers are now “acoustically coupled” with the floor and the walls.   On the other hand, if you move the speakers away from the wall and/or place them on spikes or stands (isolating them for the floor) you would have “acoustically de-coupled” the speakers from the walls and floor, which will reduce the bass or low-frequency loudness. This all affects the perceived loudness and/or quality of the music we want to listen too.

This is where the graphic equalizer shines, no need to move the speakers around or use speaker stands or spikes.  An equalizer will allow you to increase or decrease the loudness of multiple frequencies.  You can completely customize your sound to suit your tastes, overcome issues with your listening room acoustics, the speakers you are listening with or even anomalies with the music recording.

Like adjusting an equalizer to suit your room acoustics, speaker size and/or speaker frequency response, EXAIR understands that the need for many different options gives you the necessary adjustments for a successful application.  A few sizes of Air Nozzle, Air Jet or High Force Air Nozzles will not solve every application with the highest efficiency or effectiveness.  EXAIR’s air nozzle variety allows you to produce maximum effectiveness based upon the air pressure and air volume you have available.  Whether you need a strong blast or a gentle breeze, if you have tricky mounting positions or remote applications, EXAIR has the largest selection to choose from and solve your production problem.

We clearly state compressed air volume requirements in SCFM (Standard Cubic Feet per Minute) at a given operating pressure in PSI (Pounds per Square Inch), force at 12” from the compressed air outlet and the sound loudness in dBA at 3′ from the nozzle. These details provide the starting point for selecting the best air nozzle.

When you are looking for expert advice on safe, quiet, efficient, and engineered point of use compressed air products give us a call.   We would enjoy hearing from you!

EXAIR Has a New Product: The Soft Grip Super Air Scraper

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

EXAIR has designed a new nozzle called the Super Air Scraper.  This nozzle combines a scraping blade with our 2” Flat Super Air Nozzle.  It creates a mechanical force with a compressed air force to remove stubborn sticky material.  This patent-pending nozzle can be added to the EXAIR Soft Grip Air Gun to create a powerful scraping tool.

Let’s breakdown the nozzle.  The 2″ Super Air Scraper nozzle is a model 1144 which has a ¼” NPT female connection.  The model 1144-A includes a ¾ – 32 UN adaptor for connecting to the Soft Grip Safety Air Gun extensions.  The scraper can be changed when worn with a replacement blade; model 902007.  To add flexibility to the Super Air Scraper, a shim set, model 1132SS, can be used to modify the blowing force.  With these combinations, the nozzle complements the scraper as an effective way to clean with compressed air.

Soft Grip Super Air Scraper

To get pressurized air to the nozzle, EXAIR attached the 1144-A Super Air Scraper nozzle to the Soft Grip Safety Air Gun.  This gives a comfortable and ergonomic way to use and operate this product.  We offer different extensions for hard-to-reach applications ranging from 6” (152mm) to 72” (1,829mm) in length.  With the extensions that are 36” (914mm) and longer, EXAIR installed an additional foam grip sleeve.  This gives additional leverage for scraping material at a distance like floor level.  Chip Shields are also offered to prevent blow-back onto the operator.  You can view the details of the new product at this link on our website: Soft Grip Super Air Scraper.

To give some ideas for applications, the Soft Grip Super Air Scraper can be used for removing tape, gasket material, caulk, adhesive, paint, labels, and more.  With the addition of air, the detached material is blown away during scraping, keeping the area clean to target the remaining “stuck” material.  If gummy or flaky substances are a nuisance for workers, the Soft Grip Super Air Scraper can keep the machine or work station clean and operational.

Just like all cataloged items for EXAIR, we stock these parts for same day shipment with orders placed before 3 p.m. EST.  We offer a 30-day unconditional guarantee to allow you to see how great this product can work in your application.  If you have a sticky, flakey, or greasy substance that needs to be removed, the Soft Grip Safety Air Scraper is up to the challenge.  If you have any questions about the product or your “gummy” situation, you can contact an Application Engineer for help.

Think Of Quality And Service, Think Of EXAIR

As an Application Engineer at a direct sales manufacturing company, I get to talk to a LOT of people about potential uses for our quiet, safe, and efficient compressed air products. And, I’m happy to say, most of them I can even help with…even if the answer is “that’s just not gonna work.” Those are few and far between, however, and we can usually point someone in a better direction in those cases.

By the time we’ve “drilled down” into an application discussion far enough to make a product recommendation, we’ve got a pretty good feeling about it, and a vast majority of the time, our product solves the application in a big way. So big, in fact, that it makes them think of EXAIR again, and again.

Case in point: not long after I started here in 2011, I had the pleasure of helping someone out with some pick-and-place rigs on their packaging line…small products, bulk packaged for shipment to retail outlets. They used our Model 810003M E-Vac High Vacuum Generator and 900762 Small Round Vacuum Cups. Over the years, they’ve added some new products, and some more of the E-Vac pick-and-place rigs. It’s always good to hear from them, and I really believe the feeling is mutual.

EXAIR E-Vac Vacuum Generators provide a simple and reliable solution to pick-and-place applications.

Now, they want to automate a little clean-up operation where pilot holes are drilled in a plastic part, and are considering an intermittently operated vacuum. The concern is, if they use an electric powered one, the starting & stopping will take a toll on the motor. And they’re right.

So, the Model 6193-5 Mini Chip Vac System is up for consideration. Because it’s compressed air operated, constant starting & stopping is no problem…and, it’s generating vacuum immediately, so it’s ideal for quick bursts of cleanup suction action. No electric motor to burn out, no moving parts to wear – it’s a long term, maintenance-free solution.

Quiet and compact, the Mini Chip Vac is an ideal solution for a variety of industrial housekeeping needs.

If you’re an EXAIR engineered compressed air product user, I want to thank you for your business. If you’d like to discuss a particular compressed air product application (regardless of whether you’re a current user or not!) give me a call.

Condiment Sauce Recovery Using The High Lift Reversible Drum Vac

Last week I worked with a food manufacturer who makes a line of specialty sauces, with consistencies similar to BBQ sauce or ketchup, who was looking to vacuum spills off their production floors. During production, they will sometimes experience an overfill during the bottling process, which results in the product spilling on the floor. Their current clean up method is to have an operator with a wash down hose, “thin” the sauce spills with water then direct it to a drain in the floor so it can be sent to the scrap tank. This was causing a few issues though, first, the drains have filter traps that were clogging regularly from not only the sauces but other particulate that may have been on the floor, causing environmental concerns for the plant. The other concern was the amount of water they were wasting to perform the clean up. My contact was the newly appointed maintenance manager and was tasked with trying to find a more reliable, economical way to remedy the situation. He was familiar with EXAIR as he had used some of our Line Vac Conveyors at his previous employer and knew we also carried a line of Industrial Vacuums but was unsure which product would be best suited for his needs so he reached out for assistance.

After discussing the details of the application, I recommended he use our High Lift Reversible Drum Vac System. The High Lift RDV is a liquid only vacuum that provides 180″ H20 vacuum and is able to handle thicker, more viscous fluids (up to 1400 cP) than our standard Reversible Drum Vac. With the ability to vacuum liquid up to 15′, the unit comes standard with a 20′ flexible vacuum hose and has no motors or moving parts to wear out. The system quickly installs to a standard closed head steel drum with available capacities of 30, 55 or 110 gallons. For spills, we offer our optional Model # 6901 Spill Recovery Kit which includes a 54″ ABS wand and 14″ double-blade squeegee that makes floor cleanup a breeze. After the material has been vacuumed, the unit can then be set to “empty” to pump the liquid back out to their waste tank so it can be carried away by their environmental recovery supplier.

The Trusty Reversible Drum Vac, 16 Years Later

This week a customer sent us a Reversible Drum Vac to refurbish. From time to time a Reversible Drum Vac may need (depending on cleanliness of the supply air) cleaning due to particulate from the compressed air line landing inside the air chamber of the Reversible Drum Vac. EXAIR regularly rebuilds, cleans and tests Reversible Drum Vacs that customers send in to have us return them to new condition. You can also easily refurbish the Drum Vac at your facility: Here is a link to our How-To video for cleaning your Reversible Drum Vac. This particular Reversible Drum Vac though was clearly special.

16 Year Old Laser Marked Reversible Drum Vac

At first glance, the Reversible Drum Vac had been laser marked by the customer to permanently label their unit. The customer just so happened to be a laser marking shop, so I’m sure it was convenient for them. But digging deeper, the company originally purchased the unit in 1999, this Reversible Drum Vac could get its Learner’s Permit in most states. During the 16 years our customer was using the Reversible Drum Vac, we never heard from them. After 16 years they contacted us but not for a problem. They just wanted us to clean and inspect the unit to ensure maximum efficiency. This unit, though a bit dirty, was still operating very well. EXAIR put it through our refurbish process and brought it back to performance specifications that matched a new product.

The Reversible Drum Vac is a compressed air operated vacuum that attaches to a 55 gallon drum to create a vacuum that can also empty a 55 gallon drum in 90 seconds. The Reversible Drum Vac pulls a vacuum on the drum creating a siphon the pulls the liquid into the drum. With this technology the liquid never pass through the Reversible Drum Vac, which leads to its tremendous longevity. It is the perfect vacuum to empty coolant sumps, isolate contaminated liquids, or clean floor spills. The Reversible Drum Vac have no motors to wear out or impellers to clog so they last longer than their electrically operated counterparts.

The Value Of Free Stuff…Sometimes, It’s Actually Worth The Price

I visited my doctor recently for my annual check-up. During the exam, he lamented that a lot of his patients didn’t take the importance of preventive care seriously enough. I joked that I’m actually one of those people, but since my health care insurance covers an annual check-up at no charge to me, I do it simply because I’m a sucker for free stuff. Again, I was JOKING…I firmly believe in the importance of preventive health care, and strongly encourage you, dear reader, to do the same and get annual check-ups.

Well, I was HALF joking, anyway…I AM a sucker for free stuff. In fact, my doctor and I went on to talk about how effective free stuff (like t-shirts) was at getting consumers to sign up for new credit cards, magazine subscriptions, etc. We had a good laugh, and I kept laughing…until I got home and looked in my t-shirt drawer…

Of course, these kinds of promotions can be great advertising – that’s obviously why they’re so popular, and at EXAIR, we’re keenly aware of that. Now, you can’t wear our free stuff for everyone to see, but, in the case of our current seasonal promotion, you can get something very useful for free:

Through May 31st, we’re so intent on helping you get into Spring Cleaning mode that, with the purchase of one of our Industrial Vacuums, we’ll give you a FREE Vac-u-Gun. VACpromo_186x149 How can an efficient, quiet compressed air operated Industrial Vacuum help get your spring cleaning into full swing?  If you need help answering that question, give me a call.  They’re all in stock, and we ship same day (U.S.) with orders received by 3pm EST.

With so Many Vacuum Generator Choices, Which Do I Choose?

SAL                 HDLV                    E-vac

This is a very real question that we receive often from our customers. And that is why we have a full staff of Application Engineers, to answer just such a question. It is true that EXAIR has quite a variety of product that actually generates a “vacuum flow” of air. We have Air Amplifiers, Light Duty Line Vac, Line Vac, Heavy Duty Line Vac, Adjustable E-vac as well as Modular and In-Line E-vac products.  And that doesn’t even include our choices within the Industrial Housekeeping product group.

Back to the question at hand, how do I narrow my choices for which vacuum generator to use? The manner in which we approach such a question has to do with the application itself. We view the available range of product as a spectrum of choices from high volume, low vacuum (Air Amplifiers) air movers to low volume, high vacuum (In-Line E-vacs) air mover choices.

How do we navigate the choices?  It depends on the needs of the application. Allow me to give a few quick examples to give you an idea.

Example 1: The customer has a large air bag used in the trucking industry which is placed along-side a payload in order to reduce shifting during travel. The requirements of this application are that the bag be inflated and deflated in a reasonable time. The air pressure needed within the bag is considered quite low. So, in this case, we would gravitate toward using something along the lines of our Air Amplifier or Light Duty Line Vac which are more suited for this range of air moving applications where just air or perhaps light smoke or fumes may need to be transported.

Example 2: The customer has a shot blasting operation in which they need to collect the blast media back up into a central container for re-use or perhaps for recycling. In this scenario, the media itself actually needs to be moved and it is a rather dense, metal shot that needs a high velocity airflow to get it up and moving from point A to point B. Our Heavy Duty Line Vac is the perfect candidate for this kind of need as it delivers a good combination of high vacuum and high volume air movement to achieve goals of this nature.

Example 3: The customer has a reaction chamber in which they need to achieve -9” Hg (Mercury) vacuum in reasonably short time frame. Our Adjustable E-vacs work well to provide both high vacuum (even higher than HD Line Vac) and reasonably high (although lower than HD Line Vac) volume of vacuum flow. So, for applications where you have a large container on which a vacuum needs to be drawn or perhaps you have a large vacuum cup that is working with material that is considered very porous, these are the kinds of applications for which you would look at Adjustable E-vac.

Example 4: The customer has a set of 6 suction cups that are being used on a frame to pick-up a piece of window glass for placement into a window frame. With glass being a non-porous material, the customer only needs enough airflow to evacuate the area of the suction cup and hold on to the material tightly. This is the kind of application for which our In-Line E-vac would come in very handy to produce the low flow, high vacuum flow.

Where does your application fall within this spectrum of uses?  You aren’t sure?  Then contact our Application Engineering Department and speak with an Engineer today. We are glad to discuss with you and bring clarity to your application need.
