More Power? I DO Think So…

We occasionally get calls from folks who are looking for “more power” – and it always brings that classic 1990’s sitcom “Home Improvement’s” Tim “the Tool Man” Taylor to mind. Well, not so much Tim’s “more power” mantra, but the ubiquitous response from his long-suffering sidekick, Al Borland:

Al knows it.  George Foreman knows it. Lisa knows it.  Even Tim knows it, this time.

Sometimes, they’re looking for a product to replace what they’re currently using…something they’re not getting desirable results from. Other times, they have an EXAIR product in place, and it’s just not getting the job done.

Our first response is, of course, to make sure they’re getting a sufficient supply of air to their product, no matter whether it’s ours or not. If you’re familiar at all with our blogs, you know we write about this frequently:

3 Common Mistakes in Your Compressed Air System

Once we’ve made sure that the product is indeed receiving appropriate air supply, we can look at adding to the flow rate and force of the air stream. We’ve made it easy to do that with a variety of blow off products by designing them with a replaceable shim.

All of our Air Knife products (Super, Standard, and Full Flow) will ship with a 0.002” thick shim installed. These will perform superbly in a wide variety of general industrial blow off applications. If this doesn’t provide the force needed for your application, we carry Shim Sets for any Air Knife that will allow you to double, triple, or even quadruple the air flow for amplified thrust. Some common examples are stubborn debris in tight spaces (like the fins of a fin-and-tube heat exchanger) or removing oil from a corrugated surface.

From left to right: Super, Standard, and Full Flow Air Knives.

 

Like the Air Knives, our Air Wipes (Super and Standard) are built with 0.002” thick shims, which can be easily replaced for additional flow and force. Like when the Air Wipe is getting all the coolant off an extruded & machined part, but some stubborn, hair-like fibers need a little more “oomph” to remove.

 

Super (left) and Standard (right) Air Wipes come in sizes from 1/2" to 11".

Super (left) and Standard (right) Air Wipes come in sizes from 1/2″ to 11″.

Yes, those were real calls I took. Yes, they had sufficient air flow. Yes, the extra shims worked like a champ.

Similar to our Air Knife products, our Flat Super Air Nozzles also incorporate a replaceable shim. In fact, you have your choice of standard Models with a 0.015” thick shim installed, or High Power Models with a 0.025” thick shim. Shim Sets with a variety of thicknesses from 0.005” to 0.030” are available for either of these.

Our Super Air Amplifiers and High Velocity Air Jets incorporate patented shims that make for the highest amplification flows available, anywhere. These are available, from stock, in Shim Sets or individually.

High Velocity Air Jets and Super Air Amplifiers use patented shims for optimum performance and efficiency.

If you have an air blowing application that you’d like to get a little (or a lot) more out of, give us a call. Prepare for a discussion on proper air supply first (of course,) but we’ll be more than happy to help in any way that we can.

Full-Flow Air Knife Assists With Flour Recovery

I took a call from a customer who was looking for a way to recover residual corn flour on their chain and paddle, drag conveyor. As the paddles moved down the line, they would start accumulating flour which was leading to uneven batch runs and waste. After reviewing the application with the customer, they determined they were only needing to blow off the width of the paddles, so I recommend using our 18” stainless steel Full-Flow Air Knife.

The Full-Flow Air Knife provides a 30:1 amplification rate (entrained air to compressed air), to produce a high velocity curtain of air that travels the entire length of the knife. With a small profile of only 1” H x 1.25” W, the unit is the ideal choice where mounting space is limited. It is available in a 303SS material which was suitable for this wash-down application.

Full-Flow

The Full Flow Air Knife is available in aluminum or stainless steel construction, up to 36″ stocked lengths.

 

Due to the concern regarding dust, I recommended operating the unit at a gentle 20 PSIG, lowering the velocity to 3,000 FPM and reducing the air consumption to only 1.1 SCFM per inch. A simple pressure regulator is capable of adjusting the volume and velocity of output airflow in order to “fine tune” our knives per application. This would allow for the needed blowoff, as well as reduce the potential of the unwanted dust.

If you have a similar application or would like to discuss your process, please don’t hesitate to give us a call at 1-800-903-9247.

Birthdays, Submarines, and Static Eliminators

A dear friend is turning 50 this month, and I have no intention of making a big deal of it, considering the spectacle that her husband (who is younger than both of us) is no doubt going to make of it. I was reminded of her impending birthday when I read that Alvin is also turning 50 this year.

Even at this depth, Alvin doesn't look a day over 49.

Even at this depth, Alvin doesn’t look a day over 49.

Alvin (DSV-2) is a deep-dive submersible, built in 1964. Built to dive to depths of over 8,000 feet, Alvin has had quite a storied career:

  • 1966 – Used to locate a hydrogen bomb that was lost off the coast of Spain when a US Air Force bomber “had an accident.” The bomb was retrieved a few weeks later, without incident.
  • 1967 – On dive #202, Alvin was attacked by a swordfish, at a depth of about 2,000 feet. The swordfish became entangled, forcing an emergency surface. Upon removal, the swordfish was cooked for dinner.
  • 1968 – Alvin’s tender ship accidentally dropped Alvin when some steel cables snapped, in the middle of the ocean. Three crew members onboard at the time were able to escape, but left their lunches behind. Severe weather and the development of the required technology put off Alvin’s recovery for almost a full year. A full rehab of the vessel was slated. The fruit and sandwiches left behind were found to be well preserved, and soggy but edible.
  • 1986 – Alvin was used to find the wreckage of the Titanic. While the mission was making headlines at the time, it was actually a cover story for the highly classified “real” operation: the search for USS Scorpion (SSN-589), lost under unknown circumstances in 1968. In a remarkable stroke of good fortune, both vessels were found.

That’s all neat stuff, but I’m sure there are a few spine tingling stories we’ll never hear about a deep submergence vessel, operated by the US Navy, during the height of the Cold War. Another bit of interesting trivia, though, is who built Alvin: General Mills. That’s right, the breakfast cereal folks. Turns out, they had an electromechanical division back then that pioneered advances in packaging technology, and had previously applied some of their mechanical arms to other submersibles, leading them to successfully bid the project that Alvin was born from.

This, of course, is what engineers do. EXAIR has been making Intelligent Compressed Air Products, aimed at optimizing compressed air use, increasing safety, and lowering noise levels for over 31 years now. Along the way, we’ve added products, and added TO our products to meet other frequent needs of our customers.

Consider the Air Knife: the Air Knife had been a product for years when EXAIR developed the Ionizing Bar  and added it to the Air Knife to turn it into an efficient, quiet, and safe Static Eliminator. The Air Knife then provided good information toward development of the super efficient Super Air Knife which has become the hallmark of efficiency and performance within industry.  After years of successfully solving thousands upon thousands of static dissipation applications with the Super Air Knife, we recently added one-piece designs from 60 – 108” long which used to be a two piece construction.

3to54 siak

EXAIR stock SIXTEEN different lengths, from 3″ to 108″. Custom lengths are available in as little as three days.

A quick look at our complete and comprehensive line of Static Eliminator products shows that, if you’ve got a static problem – big or small – we’ve likely got a solution for it.

How To Choose An Air Knife

The EXAIR Super Air Knife has a prominent place near the front of our catalog, and THIRTEEN pages of photos, application details, performance data & specifications. It’s the most efficient and quietest product of its kind on the market, and our most diverse product offering in terms of size range, operational adjustability, materials of construction, and accessories available. For almost any general industrial air blow off application, the EXAIR Super Air Knife is the superior choice in terms of air usage, sound level, and capability.

EXAIR Super Air Knives come in a wide range of lengths, for a wide range of possibilities.

EXAIR Super Air Knives come in a wide range of lengths, for a wide range of possibilities.

As tireless champions of the causes of reducing air consumption and noise, we’re always going to promote these benefits of the Super Air Knife. Still, a caller asked me the other day, “Well, why do you still make the others?”…meaning, of course, our Standard and Full Flow Air Knives. Why, indeed:

*Given the same air supply pressure, the Standard Air Knife generates the highest force of our three styles. The amount of force applied isn’t always a prime consideration…if you think about one of the more “textbook” applications for an Air Knife, it doesn’t take a great amount of force to blow off dust and light debris from a conveyor belt…certainly this is a case where efficiency factors in: the lower air consumption of a Super Air Knife can pay for the cost difference between it and a Standard Air Knife in as little as three months of operation.

The Standard Air Knife has the highest force, for when it's needed.

The Standard Air Knife has the highest force, for when it’s needed.

Of course, if you’re blowing stubborn debris out of tight spaces, like gummy, greasy dirt that’s accumulating in the recesses of a finned tube heat exchanger, that extra force can make all the difference. No; the Standard Air Knife isn’t as efficient or quiet as the Super Air Knife, but it’s still a far cry better than a drilled pipe.

*While the Super Air Knife is pretty compact – you only need a few square inches of profile area to successfully mount it – the Full Flow Air Knife is even smaller, requiring not much more than one square inch of profile for mounting. With ports on the rear face (instead of the ends & bottom for the Super Air Knife,) they can fit in very tight quarters.

Low profile and lightweight, the Full Flow Air Knives are a great fit for tight quarters.

Low profile and lightweight, the Full Flow Air Knives are a great fit for tight quarters.

The Full Flow Air Knife is also the lightest weight for a given length. A 36” Aluminum Super Air Knife, for instance, weighs about 8lbs. The 36” Aluminum Full Flow Air Knife weighs less than 4lbs. Most of the time, 8lbs is a very manageable amount of mass to support, but there are situations where every ounce matters, and if yours is one of them, you’re looking at the Full Flow Air Knife all the way.

*The biggest (in the most literal sense) factor in Air Knife selection is, well…size. We make the Standard Air Knives in lengths to 48”, and the Full Flow Air Knives come as long as 36”. The Super Air Knives, however, are stocked in lengths from 3” to 108”, and can be coupled together for as long of an uninterrupted, steady, laminar air flow as you need.

At the end of the day, a majority of blow off applications can be handled just fine with any of our Air Knives. If you’d like to discuss your application and see which one is best for you, give us a call.

Chain-Chain-Change, Change Out That Drilled Pipe…

Life is full of change.  It might sound trite, but truer words were never spoken.  I used to get up around 6:30 on work days.  Now, thanks to my son’s middle school schedule, I’m usually seeing him out the door at that time.  Getting up earlier was certainly a difficult change at first, but it’s had its benefits.  Not the least of which is spending a little extra time with the boy in the morning.

One of our favorite things to do while eating breakfast is to watch the ‘How things are made’ types of shows. Of course, watching these types of shows with an engineer has its downside.  While we can usually explain exactly what’s happening in the process of whatever is being made, the problem is that we often do.  Meaning we wind up talking over the program, which, ironically, is one of my greatest pet peeves.  Speaking of change, guess that’s something I need to work on…

20141002_062454

At any rate, this morning we saw a show on making saltines.  At the sight of the copper pipe positioned near where the cracker dough comes off the die-cut wheel, I knew exactly what was up. ‘They’re using drilled pipe! That’s not safe and a HUGE waste of compressed air!  That’s the perfect application for a Super Air Knife!”  Guess watching these programs with an EXAIR engineer has an additional risk: We can get a little over-excited when we see OSHA violations and wastes of compressed air! I think I about made my son jump out of his gym shorts, but he’s watched these sorts of shows with me before.  He knew the risks…

Life is full of change, and while perhaps I can get better at not talking while the TV show is on, I doubt I’ll ever stop cringing at safety violations and wasting compressed air.  Do you have drilled pipe in your plant?  If so, you could be in violation of multiple safety standards and are definitely wasting money on compressed air.  EXAIR can help you minimize harmful noise levels and keep you in compliance with OSHA’s dead-end pressure standard. Please give EXAIR a call to begin saving air and increasing safety!
