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.

What’s In A Name?

Well, a lot, actually…if that name is EXAIR. I wrote a blog just last week about how a set of Super Air Knives solved a MAJOR problem with a brand new aluminum sawing application – the company got those Super Air Knives on the recommendation of the Maintenance Supervisor, who had used them, with great success, at a previous company.

Even more recently, I had the pleasure of helping a caller from an engineering firm that specifies a wide range of our products for use in their OEM machinery:

*Air Knives & Nozzles for automated blow offs.
*Cabinet Cooler Systems for electrical/electronics heat protection.
*E-Vac Vacuum Generators for end-of-arm robotics “pick & place.”

Turns out, they use a good amount of compressed air in their manufacturing facility and (did I mention they’re an engineering firm?) they’re interested in implementing a facilities resource management program. For one part of this, they want to know how much compressed air they’re using, when they’re using it, and what they’re using it for. And when presented with a question about compressed air, they thought about EXAIR…and wanted to know more about the Digital Flowmeter.

We discussed everything from theory of operation, to best practices for installation (location, position, etc.,) to accuracy, to getting the flow data…and we’ve got a few options for that:

*The Digital Flowmeter itself can output a 4-20mA signal, or there’s an optional RS-485 output board available.
*The USB Data Logger connects directly to the Digital Flowmeter and records flow rate data – about 9 hours’ worth if measured once a second; 2 years’ worth if measured every 12 hours. When removed from the Digital Flowmeter and plugged into your computer, you can use its software, or Microsoft Excel, to view & analyze the data.
*The Summing Remote Display offers instant indication of current flow rate, previous 24 hours’ air consumption, and cumulative total usage, all at the push of a button.

The latter turned out to be the best fit for my caller – the main supply header runs right past his office, and, if he can sell his facilities folks on it, he can install the Summing Remote Display on the wall, right next to his desk.  Easy as that.

EXAIR’s Intelligent Compressed Air Products have made a name for themselves in many places like this. Here at the factory, we’re all dedicated to spreading, and reinforcing, that reputation for excellence. If you’d like to find out more, give me a call.

We Like Safety, Yes We Do

If you’re even just a casual reader of our blogs, you likely know that EXAIR Corporation is focused on efficiency and safety. Our Design Engineers (starting with our founder & CEO) have always, and continue to be, determined to produce the most efficient, quietest, and safest compressed air products you can find. Our Production Team not only manufactures these products in strict compliance to these designs, but they do so with keen attention to safety in every evolution of every operation, from machining and assembly to packaging and quality control, and all points in between. Getting hurt on the job here is the last thing someone has to worry about, because safety is the first thing everybody is thinking about. And I really, really like that.

I had the pleasure of helping a caller recently who was focused on that exact same thing: workplace safety. They operate a brake press, and, in continuing efforts to improve safety, had been using tongs to place parts into, and retrieve them from, the press platen. Some of the parts weigh about 1-1/2 pounds, and the tongs were, necessarily, a two-hand operation. As you can imagine, this was a laborious and tiresome process, involving hundreds of operations over the course of the day. The main concern was still safety, of course, but they were also looking for a lighter-weight, more ergonomic solution, so we started talking about a simple pick-and-place device, using an E-Vac Vacuum Generator and a Vacuum Cup.

Again, the largest part weighed only 1-1/2 pounds, and was about 8” in diameter. This was easily handled by a Model 900753 Small Round 1-1/2” Diameter Vacuum Cup. Given the light weight of the parts, and the compact (by design) nature of their device, they were able to use our smallest Model 810002M In-Line E-Vac High Vacuum Generator, which uses only 2.3 SCFM @80psig.

With (14) Models to choose from (seven sizes, all available in "High Vacuum" for non-porous products and "Low Vacuum" for lifting objects with a porous surface,) we've got the solution to your pick-and-place application.

By incorporating a simple thumb-trigger air gun and an arrangement of short pipe nipples, fittings, and elbows, they were able to quickly assemble a lightweight, ergonomic pick-and-place tool to replace the cumbersome tongs…and still keep the operators’ hands safely away from the press platen. Add in the fact that it’s now a one-handed operation, it’s a win-win-win. And I really, really, like that too.

If you’d like to find out how a pick-and-place system using EXAIR E-Vacs and Vacuum Cups can make life easier in your machine room, fab shop, or even shipping & receiving, give me a call.

Help with Choosing an E-Vac Vacuum Generator

This is a pretty common question when it comes to Vacuum Generator use in pick-and-place application, and although we can’t boil it down to a simple table & formula based on mass (like we can with the Vacuum Cups themselves,) we can usually hone right in on it, if we have enough details of the situation. And, if questions remain, we can always test one to find out…we’ve got an Efficiency Lab.

That’s what I did, first thing this morning. I had the pleasure of speaking with a robotics instructor at a vocational school yesterday…his class was building a robot to enter in a competition, and one of the operations it needs to accomplish is picking up a golf ball and carrying it a certain distance.  This sounded like a great application for a small E-Vac Vacuum Generator, and, considering the potential leakage at the Vacuum Cup face from the dimples on the golf ball, my first instinct was to consider our Model 810002M E-Vac Low Vacuum (Porous Duty) Generator w/Muffler, and a Model 900766 Bellow Style Vacuum Cup, with a 0.73″ diameter face…our smallest, and ideally sized for a golf ball.  They, however, have a VERY limited supply of compressed air, so the difference between the Model 810002M’s compressed air consumption (2.3 SCFM @80psig) and the Model 800001M E-Vac High Vacuum (Non-Porous Duty) Generator w/Muffler (1.5 SCFM @80psig) was worth considering.  Also, we figured that they might be able to use a Model 900804 Check Valve, so the only time they’d need to supply air was to pick it up, and, possibly intermittently to maintain the vacuum.  So, golf ball in hand, off to the Efficiency Lab I went.  I also took our trusty video camera:

As you can see, it locked on to the golf ball instantly, and the Check Valve allowed the Vacuum Cup to hold the ball for over 13 seconds with no air flow to the E-Vac, proving that there isn’t much leakage at all past those dimples.  I suspect we’ll be seeing this robotics class team in the winner’s circle at the competition.

In most cases, the difference between 1.5 SCFM and 2.3 SCFM consumption may go unnoticed when picking a short-duration pick-and place vacuum generator.  The higher usage product’s supply pressure can always be regulated down to reduce compressed air consumption and use only what’s necessary to do the task…we, in fact, recommend that on ANY compressed air application.  In this case, though, it was worth finding out.

If you have a pick-and-place application that you’d like help with in selecting the right system, give me a call.
