A Line Vac Air Operated Conveyor System Really IS Just That Simple. Seriously.

I’m a skeptic by nature. “If it sounds too good to be true, it probably is”, is engrained in my cerebral cortex as firmly as anything else. And I know I’m not the only one, if only because of the conversations I have with callers about our Line Vacs. Here are some of the questions we’ll get:

“What all do I need?” Here’s a basic system:

A Line Vac.
A length of hose to get from Point A to Point B.
A supply of compressed air.
Something to convey.

That’s it.  You might need something to hold the hose in place.  Or maybe a Mounting Bracket for the Line Vac to hold IT in place…if so, one comes in the Kit.  Which brings me to the next question…

“What ELSE do I need?”

This depends on what you’re conveying.  Anything in your compressed air supply to the Line Vac can get on (or in) the product passing through.  Our Kits include an Automatic Drain Filter Separator, which keeps the air clean & dry.  If you need to keep any trace of oil from your product, we’ve got Oil Removal Filters, which can couple right to the Kit’s Filter Separator.  Not only do they use a coalescing action to remove any trace of oil, they provide additional particulate filtration down to 0.03 microns.  THAT’S some clean, dry air right there.

“What’s the catch?”

By and large, the mission of the Application Engineering staff at EXAIR is to eliminate any “catches.”  We’ll discuss your application with you and make just as solid of a recommendation as we can with the data provided.  We’ll talk about:

The physical nature of your product.  If it can make a combustible mixture with air, we won’t specify a Line Vac.  If it’s particularly low density, we’ll discuss the Light Duty models.  If it’s abrasive or particularly high density, we’ll go to the Heavy Duty models.  If it’s corrosive, we’ve got Stainless Steel.

The environment it’ll be used in.  If it’s hot (or corrosive, like the product,) we’ve got Stainless Steel.  If it’s REALLY hot – up to 900F (482C) – we’ve got High Temperature units.

How you want to hook it up.  We’ve got Conveyance Hose for our standard Line Vacs…it’s reinforced PVC and is awesome for typical industrial/commercial uses.  If you want to use hose with specific properties (food grade, static resistant, high temperature, etc.,) these are all readily commercially available, and are quite commonly seen in successful Line Vac installations.  Our Threaded Line Vacs can be used with NPT pipe fittings & connections for more permanent setups.

Lastly, the “catch” is ours…not yours.  If, after a thorough discussion (mind you, I can talk about Line Vacs all day long…and sometimes I do,) there are still some variables or unanswered questions, we offer all catalog products with a 30 Day Unconditional Guarantee.  Try it out – if it doesn’t do what you want, we’ll arrange return for full credit; easy as that.  It’s the complete absence of “catch.”  Oh, and if you buy a Line Vac before October 31, 2016, you’ll get a free 2″ Flat Super Air Nozzle.

If you’ve got a Line Vac – or any Engineered Compressed Air Product – application you’d like to discuss,  give me a call.

Celebrating The Chip Trapper

NFL Football season is officially under way, and my hometown team, the Cincinnati Bengals, are off to a solid start. With less than a minute left in the game on Sunday afternoon, an interception stopped the New York Jets’ final drive, and Who-Dey Nation began to celebrate the win. Some (not me…not as far as you know) may have even celebrated in accordance with a hallowed Bengals tradition:

While I won’t celebrate just ANYTHING (although I do indeed hold prompt service at the deli counter in high regard,) you might get me excited enough to do the Ickey Shuffle if you start talking about how much you like your Chip Trapper.  Just like a caller did this morning.

Now, I’m unabashedly proud of all of our products, so I’m not going to come right out and SAY that I have a favorite any more than I would publicly proclaim one of my children as my favorite.  Although, in all fairness, they’re teenage boys, so at any given time, one of them is quite likely edging out the other on The List.

But back to the Chip Trapper – this morning’s caller just wanted to order some more Filter Bags, but in the midst of our conversation, he started “writing the commercial” for the product:

*It’s extended the life of their coolant – regular removal of solids and particulate contamination means the coolant stays clean & effective.

*It ensures the reliability of the machine – clean coolant doesn’t clog the lines, which WILL wreck the part you’re machining, and probably the tooling too.

*It eliminates odors – OK; nobody ever brags about a “spring fresh” aroma in a machine shop, but bacteria-laden, rancid coolant is the WORST.  Nobody needs to be working around that.  And since that bacteria needs solid surfaces to grow on, filtered coolant is fresh coolant.

*It’s EASY (part 1) – it’ll pump 55 gallons of dirty coolant into the drum in about 90 seconds.  Turn the valve and reverse the direction of the Reversible Drum Vac, and it’ll pump freshly filtered coolant back into the sump just as quickly.

*It’s EASY (part 2) – the Filter Bag holds over 5 gallons (almost 3/4 of a cubic foot) of chips, and the system comes with two of them so you can use one while cleaning out the other.

EXAIR's new Chip Trapper
EXAIR’s Chip Trapper comes in 30, 55, or 110 Gallon Sizes, depending on your needs.

If you’ve got a machine shop and DON’T have a Chip Trapper (yet,) call me; let’s talk.  If you DO have a Chip Trapper and you like it as much as my caller today did, DEFINITELY give me a call.  I might even do the Ickey Shuffle with you.

Stop Trying To Squeeze More Out Of That Air Gun!

At EXAIR, we LOVE to talk about efficient use of compressed air. That’s why I was thrilled to get a call from an engineer that works for a non-profit firm that promotes energy efficiency to enable businesses in their area improve sustainability, improve the environment, and save money.

They were working with a local company to, among other things, optimize their use of compressed air and wanted to take advantage of our free Efficiency Lab service to get the “before” data on the current blow off devices.

Don't let this happen to your air gun...use an EXAIR Precision Safety Air Gun with a quiet, efficient Super Air Nozzle instead.

As you can see, they were trying to “squeeze” a little more performance out by, literally, squeezing the tip down.  Thing is, it’s STILL loud and non-compliant with OSHA’s regulations about dead end pressure.  And as far as performance goes, this results in only a slight change in the air flow pattern, with a minimal reduction in compressed air consumption…they’ve changed the geometry of the discharge opening, but not the cross sectional area.  Our Efficiency Lab Test results provide the final answer:

cry for help lab

Efficiency. Saving money. Safety. Sustainability. “Going Green.”   If you’d like to talk about how EXAIR can help you with any…or all…of these things, give me a call.

The Super Air Knife: It’s Super Easy To Install

One of the more commonly asked questions about one of our more commonly asked-about products is:

“How do you install a Super Air Knife?”

Well, I’m glad you (or, in this case, “they,”) asked! There are several options, and they’re all pretty simple:

The Universal Air Knife Mounting System – right out of the box, the 9060 Universal Air Knife Mounting System is ready to go. It gives you a complete range of motion, so changes to the angle, direction, and distance of the air flow to the target are quick and easy. Multiple systems provide secure support for longer Air Knife lengths.

The 9060 Universal Air Knife Mounting Systems are perfect for simple, fast installation and positioning.

The Air Knife Plumbing Kit – Air Knives 24″ and longer need to be supplied at multiple inlets.  A Plumbing Kit comes with everything you need to get that down to just one (lengths to 54″) or two (lengths to 108″) 1/2 NPT connections, saving you from hunting down the fittings and hose or tube, while ensuring you get sufficient air flow for optimum performance.

Plumbing Kits

The Super Air Knife Itself (part 1) – because the Air Knife cap & body are held together with a series of Stainless Steel cap screws, there’s a 1/4″-20 tapped hole, about 3/8″ deep, every 2″ along the bottom of the body. These are commonly used to install the Air Knife to an acceptable mount.

If you've got something to hold it to, mounting a Super Air Knife with 1/4"-20 fasteners is a snap!
If your equipment already has rails or a frame, mounting a Super Air Knife with 1/4″-20 fasteners is a snap!

The Super Air Knife Itself (part 2) – like I said above, when they get longer than 24″, an Air Knife needs to be supplied at both ends to ensure proper air flow across the entire length. There are MANY Super Air Knives installed over conveyor belts (a “textbook” application) that are simply supported by hard piping to both ends. The Air Knife is, essentially, as well supported as the piping.

Use the supply piping to adequately support longer lengths of Super Air Knives

The Super Air Knife Itself (part 3) – I saved “part 3″ to talk about the 3” Super Air Knife specifically…see what I did there? These short, compact units can actually be supported and plumbed properly, using a Magnetic Base and a Stay Set Hose.

Install and reposition a 3" Super Air Knife using any steel surface with a Mag Base & Stay Set Hose.

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.

EXAIR's Remote Summing Display - see current flow rate, previous 24 hours' consumption, or total cumulative usage, at the push of a button!
EXAIR’s Summing Remote Display – see current flow rate, previous 24 hours’ consumption, or total cumulative usage, 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.

EXAIR Has Solutions For Skin Problems (Really)

The EXAIR Chip Trapper filters solid debris from your coolant that can not only clog the supply lines to the tooling, but also provide a LOT of surface area for the growth of bacteria. This can really foul the air in a machine shop, and sometimes, it can mess with your skin, causing a rash or infection. Honestly, this isn’t a HUGE problem…I’ve fielded a handful of calls about it over the years, though, so when I got the call from a machinist last week who wanted to talk about a possible solution for a skin problem, I immediately thought of the Chip Trapper.

Well, immediately after I thought about this old commercial (I’ve written before about how I watched way too much television growing up. Don’t judge.)

Turns out, though, his problem wasn’t bacterial – it was an allergic reaction he was having with a specific additive in the coolant used on a particular machine tool. He mentioned that it was a mist coolant application, so I immediately thought of the Cold Gun Aircoolant System.

Of, course, right after I thought about this commercial (seriously; stop judging.)

To my knowledge, it’s the first time we’ve ever applied a Cold Gun to solve a skin problem – we’re almost always looking at them to avoid the mess of coolant spray, or to increase tool life in situations where traditional machine tool coolant is impractical (or impossible) to use.

With four distinct models to choose from, we've got a Cold Gun System to meet your needs.

If you’d like to find out how EXAIR products can save you from:

*Excessive compressed air consumption
*High sound levels
*Static charge problems
*Heat damage to your electronics
*Labor intensive “bucket and ladder” bulk conveyance operations
*Trips to the dermatologist (no, really)

Then give me a call.  We can even talk about vintage TV commercials (I won’t judge either.)
