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.

Static Eliminators Solve Printing Quality Issues

One of the big issues in winter many manufacturing and process industries experience is static.  An outside sales rep who was responsible for selling and servicing industrial laser printers contacted us after he started to receive more complaints about the quality of the print, especially with customers that used polyester sheets.  One of their customers was printing both sides of a 13” X 19” (33 X 48 cm) sheet, and they noticed that the print on the back side was blurry.  We discussed how static can cause issues like this in printing applications. A static charge can keep ink from landing in the proper location, it can cause ink to spiderweb, spread over defined boundaries or fail to penetrate its target.

Ionizing Bar

Low cost Ionizing Bars eliminate static cling.

Being that EXAIR Corporation is a leader in production and application of active Static Eliminators, we were able to discuss the issues and suggest some possible solutions. Laser printers are designed to use static to pick up toner onto a drum and to apply it to sheets of paper.  If the sheet of paper has a charge on it, that can affect the print quality because like charges repel each other.  In this application, we have two conditions that contributed to the increase in static charge on the polyester sheet, the dry air and the type of material.  Dry air in winter is pretty much a given as cold air cannot hold as much moisture as hot air can.  With a decrease in moisture levels, static fields can build to much higher levels causing discharges, the small “shocks” you experience when you touch a non-conductive material, another person or even a grounded machine.  The other static issue is material.  The type of materials involved in an application determine how they will share electrons when they rub together.  Some materials give up electrons readily and some materials tend to gain electrons.

Getting back to the application; inside the mentioned printer, a rubber roll was used to invert the paper to print on the back side.  If the paper was cellulose, it is harder to generate static as the rubber roll and cellulose are similar in sharing electrons. However, this sheet was made of polyester, it has a higher affinity to take electrons from the rubber roll. A static field would build which was enough to affect the transfer of toner from the drum causing a blurred image.

Our strategy for applying static elimination solutions is to determine the point of static generation and locate the static elimination equipment just downstream of the problem area.  In this instance, it was after the roller just before printing. The space was limited, so the customer went with model 7012 Ionizing bar with the 7901 power supply.  The positive and negative ions that are emitted from the Ionizing Bar will neutralize static fields of positive or negative polarity bringing the surface of the polyester material back to neutral.  The length of the bar was slightly shorter than the width of the sheet, however it still has plenty of capacity to neutralize the outside edges.  The end user mounted the Ionizing Bar in the center of the sheet about 0.5” (13mm) away from the surface.  After he plugged in the Ionization Bar, the static field was removed and the printing on the back side was now clear.  The end user was so impressed that he contacted the manufacturer of the laser printer to suggest they add effective static elimination as  an option for troublesome applications like his.

If you have static issues and you want to remove the pain they cause in the form of injury, lost production time and material waste, contact EXAIR and speak to one of our experienced Application Engineers.

Another Piece To The Puzzle

With having three young children, puzzles are a very popular item in my house.   Whether it is a wooden puzzle where you are matching different color fishes into their corresponding recess on a board, or maybe a classic Rubik’s Cube that I will get half way through solving when one of my daughters wants to help mess it up.  (Which I absolutely love to help them do because I watch their face as they turn each side and it is simply a look of pure joy and amazement. No matter the case, the puzzles always get solved and then they are guaranteed to be done again.

Cabinet Cooler

Here at EXAIR, I look at nearly every application I come across as a puzzle.   Sometimes, we have the exact piece that has a precise place and fit.  This could be a Cabinet Cooler System to cool and overheating electrical panel.  More often than not, it’s not that easy.  We spend a good margin of our time creating a picture in our head of what the customer’s application is and we try to find that missing piece to the puzzle that will complete their needs.

This is one of the great things about the Application Engineering Department here at EXAIR, each one of us has a very diverse professional background and very different life experiences which permits us to cover just about any scenario you can throw at us.  If one of us hasn’t experienced it, there is a good chance we have someone outside of our department who has and we will bring them in on the problem solving.  It’s not too uncommon for certain applications to even make it into the eyes and ears of the President of EXAIR due to his extensive background with many industries.

The point is, if we can’t figure it out, we know who to ask, if they don’t know, we’re going to try our hardest to get you the right product to fit your needs and exceed your expectations the first time. If not, we honor a 30 day guarantee on stock products and will take the product back so you know that we have exhausted all options.   We’ve even been known to call former customers back when we come out with new products that will fit their needs we weren’t able to meet.

Line Vac Solution For Fiberglass Application

150200

Recently, I worked through a project with an end user in the UAE in need of a more viable material transfer system. As a manufacturer of fiberglass liners, they developed a need to convey a mixture with properties similar to cement approximately 10’ vertically. At the end of this conveying distance is a hopper, situated atop a machine used to mix the compound needed for production.

Presently the material is transferred from a small storage silo to the hopper by hand, but such a setup has proven to be insufficient and time consuming. After working with the end user to determine the bulk density of the material and the required conveyance rate, it became apparent that a single Line Vac would not have sufficient transfer capabilities to keep up with the demand. However, if two Line Vacs could be run in parallel, our solution became much more feasible.

By installing two 150200 Line Vacs to move the material, the end user is expecting to meet the needs of production, and to transfer the material into the hopper at a more productive and efficient rate. In this application the need is for non-continuous material transfer at a high rate, so the parallel Heavy Duty Line Vacs provided a perfect solution.

EXAIR products and staff are in place to provide solutions. If you have an application problem, contact an EXAIR Application Engineer.

A Special Build

machining

The number of calls and emails that come in every week always seem to have something new.  Looking through my emails this afternoon I saw an product integration walk-through for a Line Vac, but with a twist.  This particular application had been mimicked in another facility and in looking at the specs, the requested model didn’t seem to fit quite right.  After a few emails and a sketch of the installation, everything was worked out with a safety margin to ensure proper application performance.

I also noticed the telltale signs of summer, which was an abundance of Cabinet Cooler Sizing Guide assistance forms.  There were a number of others dealing with Cabinet Cooler Side Mount Kits, Air Nozzles, Air Knives, Reversible Drum Vacs, etc.  In short, there hasn’t been a shortage of fresh applications to keep me on my toes and asking questions.

One of the questions that stood out to me this past week was whether we are able to offer our Threaded Line Vac products with BSPP threads, and the answer is yes.  Unsurprisingly the request came from an overseas source, and also unsurprisingly we are stepping up to fill the need.  We pride ourselves on building reliable products and having them in stock, but we also pride ourselves in being able to step out of the production manufacturing zone and modify our designs when you need a custom solution.

If you’re involved with our product and see the need for a BSPP thread, or another modification to suit the market, drop me an email and I’ll see what we can do.
