UThisThat_LIVEOD_600x150

Not much in life is free anymore. So, make sure and take advantage of EXAIR’s upcoming FREE webinar at 2:00 PM ET on 10/17/2019. Not only are we providing it for free, but in this webinar we’ll be discussing how you can save money by reducing your compressed air consumption. Something for free, that will help save you money? Almost unheard of these days!!! Hosted by one of our highly-trained Application Engineers, Jordan Shouse, you’ll learn about four common ways that you can easily save air in your facility.

Compressed air is often referred to as the fourth utility in industry. When used improperly, compressed air is extremely expensive. Homemade devices such as open-ended and drilled pipes, inefficient air nozzles, leaks, etc. all contribute to increased energy costs. In addition to being wasteful, these devices are not safe and compliant with OSHA standards and regulations. By using an Intelligent Compressed Air Product, you’ll be both saving money and creating a safer environment for your operators.

In this webinar, you’ll gain an understanding of the places in your facility that are wasting the most compressed air. We’ll educate you on the various engineered solutions available from EXAIR to help eliminate unnecessary compressed air usage. You’ll gain the knowledge necessary to determine the best solution based on the application, sound level, compressed air usage, and compliance with OSHA safety requirements. You’ll also learn about the various solutions available to help understand and optimize your compressed air system. You can’t begin implementing a plan to reduce air consumption until you fully understand the usage in your own facility and processes. EXAIR’s line of Optimization products are ideal to help you gain a baseline measurement and begin implementing new products and processes that’ll only help add to your bottom line.

EXAIR Line Vacs: Dozens Of Models; Endless Applications

With 119 distinct Models, EXAIR Line Vacs are used to convey everything from down feather to steel shot.  They’re versatile, reliable, durable, and incredibly easy to install and operate.  Consider this list of uses, starting with our smallest Line Vac, and going to our largest:

  • Model 6058 3/8″ Stainless Steel Line Vacs pull mica from a bulk container and spray it into a mold for making decorative stones, to apply a glittery surface.  They used to do it by hand, but the Line Vacs spread it more consistently.
  • A Model 6079 1/2″ Aluminum Line Vac pulls small metal scraps from a metal trimming operation, as they’re cut, keeping the work area clean.
  • Model 130075 3/4″ Light Duty Line Vacs perform a similar function in a plastic cutting machine, conveying away cut chips and eliminating the need for periodically stopping the machine to clean up.
  • A medical device manufacturer saw a 50% increase in productivity when they went from removing flash by hand from molded silicon parts to using a Model 6061 1″ Stainless Steel Line Vac to suction it away automatically.
  • A mining equipment manufacturer reclaims sand from a secondary operation on their green sand molds with a Model 6062 1-1/4″ Stainless Steel Line Vac.  This keeps their mold area clean, and has eliminated waste in production.
  • Model 140125 1-1/4 MNPT Aluminum Threaded Line Vacs eliminated a  “bucket and ladder” operation where cotton seeds needed to be loaded into 7-foot high hoppers.
  • Model 151150 1-1/2 MNPT Heavy Duty Threaded Line Vacs, fitted into black iron pipe systems, reclaim hot metal chips from a deep channel milling machine, automating the transfer to the recycling hopper.  This eliminated the risk of lifting AND burn injuries from the manual handling of the hot chips.
  • Model 6084 2″ Aluminum Line Vacs vacuum trim scrap from custom label making machines to a central scrap bin, keeping the floor clean, and keeping operators from having to empty individual bins at each machine.
  • A Model 6065 2-1/2″ Stainless Steel Line Vac conveys rejected peanuts (identified and segregated by a vision sorting machine) from the catch pan to a large collection hopper.  This is hauled away at the end of each shift, instead of an operator paying constant attention to the catch pan.
  • Model 161300-316 3″ Sanitary Flange Line Vacs replaced mechanical conveyors in a grain mill, incorporating a totally enclosed Clean In Place (CIP) system.  This greatly reduced contamination controls when the product was openly conveyed, and actually increased their conveyance rates of their bulk grains.
  • A Model 6087 4″ Aluminum Line Vac conveys an additive (in pellet form) into an asphalt mixer, replacing an auger conveyor that left product in the hopper and would clog regularly, resulting in messy spills.
  • A company that recycles spent ammo from gun ranges uses a Model 6088 5″ Aluminum Line Vac to convey the granulated rubber backstop material into their truck.  After the ammo is separated, they use the Line Vac to replenish the granulated rubber into the backstop.
  • A Model 130600 6″ Light Duty Line Vac conveys linen squares (mostly 12″ and 24″ square) through the main header of a sorting operation in a commercial laundry facility.  The system also incorporates several Model 120024 4″ Super Air Amplifiers in individual “pickup” branches.
The EXAIR Line Vac is a fast, low cost way to convey most any bulk material.

No matter what kind of bulk material you need to move, EXAIR has a Line Vac product for it.  If you’d like to find out more, give me a call.

The 2″ Flat Super Air Nozzle is more durable than plastic flat nozzles, operates at lower noise levels and produces a powerful blast of compressed air in a laminar sheet.

line vac family
Lightweight and durable aluminum is the most popular choice, but we make them in stainless steel (Types 303 and 316) for heat and corrosion resistance. For extreme heat, the High Temperature option affords protection to 900F (482C) in either 303SS or 316SS.

Line Vacs provide a fast, easy way to pneumatically transfer dry materials from one location to another.  They eliminate the need to have personnel manually transferring materials via bag, super sac, or bucket-and-ladder setups.  Doing so reduces worker fatigue and allows conveyance to occur simultaneously with other process operations.

The Line Vac conveys scrap trim quickly and easily, and can be sized for most any product.

 

 

 

 

 

 

 

 

 

Depending on application parameters such as bulk density of the material (lbs/ft³ or kg/m³), conveyance height/distance, and required conveyance rate, we can size a Line Vac properly through the support of our Application Engineers who have years of experience working with these products and their implementation into industrial solutions.

We’re here to help you find a pneumatic conveyance solution for your application, and earn a free nozzle in the process.  Contact our Application Engineers for assistance today.

Adjustable Spot Cooler Keeps Rollers Rolling

A manufacturer of automotive power transmission shafts was experiencing frequent failure of high pressure plastic rollers on their spin tester.  There are four rollers in a 90° array that center the shaft during spin testing.  They exert a pressure of around 1,500psi onto the shaft while it’s rotating at 1,000rpm.  This generates enough heat to actually melt the rubber coating on rollers, which means stopping testing (which holds up production) while they change out the rollers.  Just for it to start all over again.

This, of course, was an ideal application for a Vortex Tube cooling solution.  They wanted to aim the cold air flow from the dual points of two Model 3925 Adjustable Spot Cooler Systems at four points of the shaft, right where it starts to contact the rollers.

Model 3925 Adjustable Spot Cooler System has a Dual Outlet Hose Kit for distribution of cold air flow to two points.

Thing was, they wanted to mount the Adjustable Spot Coolers where they could have access to the Temperature Control Valve, but the cold air Hose Kit wouldn’t reach the shaft.  So they got a couple of extra sections of the cold air hose…they needed one section of the ‘main’ (shown circled in blue, below) to reach into the test rig’s shroud, and two sections of the ‘branch’ (circled in green) to reach to each roller.

If you need a little extra reach from an Adjustable Spot Cooler or a Cold Gun, the cold air hose segments snap together, and apart, for any length you need.

Now, adding too much hose length will start to put line loss on the cold air flow, and it will pick up heat from the environment.  But if you just need that extra foot of hose to get the job done, this generally works just fine.  The extra foot or so they’ve added (5″ to the main and 6″ to each branch) has solved their problem…they haven’t had to replace a roller since the Adjustable Spot Cooler Systems were installed.

If you’d like to find out more about how EXAIR Vortex Tubes & Spot Cooling Products can prevent heat damage in your operation, give me a call.

Don’t Forget About Operating Cost: How To Calculate Return On Investment

If you have a stock portfolio, or even a retirement account, you’ve likely heard the term “return on investment.” It basically tells you how hard your money is working for you, and, the higher, the better.

The term is also used to determine the financial benefits associated with the use of more efficient products than you’re using right now:

  • The cost of operating industrial pumps, air compressors, and a variety of industrial rotating equipment, can be greatly reduced by using variable frequency drive systems that sense the demand and change the motor’s speed (and hence power consumption) accordingly.  These systems are not cheap, but the reduction in operating costs is often quite noticeable.
  • At home, installing energy efficient windows (spoiler alert: your builder probably used the cheapest ones he could find…mine sure did) or upgrading appliances & HVAC can cost a pretty penny, but you’ll also see your electric bill go down.

EXAIR Corporation has a worldwide reputation for providing highly efficient compressed air products for industry.  Our Engineering Department has a company-wide reputation for being data fanatics…which is key to allowing us to provide our customers with ample information to make the best choices to optimize your use of your compressed air.

It’s not hard at all to calculate your potential savings from the use of an engineered compressed air product, assuming you know how much air your current device is using.  If not, we can tell you if you can send it in for Efficiency Lab testing (free and fast; call me to find out more.)  Here’s an example for a VERY typical situation: replacing an open copper tube blow off with an EXAIR Super Air Nozzle:

  • A 1/4″ copper tube uses 33 SCFM @80psig
  • A Model 1100 Super Air Nozzle uses 14 SCFM @80psig

33 SCFM X 60 min/hour X 8 hours/day X 5 days/week X 52 weeks/year = 4,118,400 SCF

14 SCFM X 60 min/hour X 8 hours/day X 5 days/week X 52 weeks/year = 1,747,200 SCF

4,118,400 – 1,747,200 = 2,371,200 Standard Cubic Feet of compressed air savings

If you know your facility’s cost of compressed air generation, you can calculate the monetary savings.  If not, we can get a good estimate via a thumbrule used by the U.S. Department of Energy that says it typically costs $0.25 to generate 1,000 SCF of compressed air:

2,371,200 SCF X $0.25 ÷ 1,000 SCF = $592.80 annual monetary savings

In 2019, the cost of a Model 1100 Zinc Aluminum Super Air Nozzle is $41.00.  Daily savings (not counting weekends) is:

$592.80 ÷ 260 days (5 days/week X 52 weeks/year) = $2.28 daily savings

Meaning the payoff time for the $41.00 investment in the Model 1100 is:

$41.00 ÷ $2.28 = 17.9 days

Or…just over three weeks.  Now that I’ve shown you the math, I’d like to introduce you to the EXAIR Cost Savings Calculator.  Just enter the data, and it’ll check your math (because I know you’re going to do the math anyway, just like I would.)  It even does the ROI for you too.

Engineered solutions (like EXAIR Intelligent Compressed Air Products) are the efficient, quiet, and safe choice. Does the one on the right look familiar?  It’s literally the example I used for the above calculations.

If you’d like to find out more about how – and how fast – EXAIR Intelligent Compressed Air Products can pay off for you, give me a call.

About Heat of Compression Dryers

Drying compressed air is similar to removing the humidity in the air when using an air conditioning system.

From a functional standpoint, what does this really mean?  What will take place in the compressed air system if the air is not dried and the moisture is allowed to remain?

The answer is in the simple fact that moisture is damaging.  Rust, increased wear of moving parts, discoloration, process failure due to clogging, frozen control lines in cold weather, false readings from instruments and controls – ALL of these can happen due to moisture in the compressed air.  It stands to reason, then, that if we want long-term operation of our compressed air products, having dry air is a must.

desiccant-dryer
A Heat of Compression regenerative desiccant dryer for compressed air

 

A heat of compression type dryer is a regenerative desiccant dryer which uses the heat generated by the compression of the ambient air to regenerate the moisture removing capability of the desiccant used to dry the compressed air.

heat-of-compression-regenerative-desiccant-dryer-diagram.png

When using one of these dryers, the air is pulled directly from the outlet of the compressor with no cooling or treatment to the air and is fed through a desiccant bed in “Tank 1” where it regenerates the moisture removing capabilities of the desiccant inside the tank.  The compressed air is then fed through a regeneration cooler, a separator, and finally another desiccant bed, this time in “Tank 2”, where the moisture is removed.  The output of “Tank 2” is supplied to the facilities as clean, dry compressed air.  After enough time, “tank 1” and “tank 2” switch, allowing the hot output of the compressor to regenerate the desiccant in “tank 2” while utilizing the moisture removing capabilities of the desiccant in “tank 1”.

If you have questions about your compressed air system and how the end use devices are operating, contact an EXAIR Application Engineer.  We’ll be happy to discuss your system and ways to optimize your current setup.

EXAIR Gen4 Ionizing Bar Removes Static From Corona Treated Plastic

If you want to print on plastic, it’s challenging – most plastics are chemically inert and non-porous.  That means you can apply all the ink you want; it’s not going to stick.  In the 1950’s, a Danish engineer named Verner Eisby experimented with various techniques to overcome these challenges.  He found that exposing the surface to be printed on to gas flame or sparks modified the surface to improve adhesion with the ink.  It did so, though, in a crude & uneven manner, leaving imperfections & inconsistencies in the printed product.  He then tried applying a high frequency corona discharge in a linear array.  The plasma (gas in an ionized state) generated left a homogeneously treated surface on which to print, smoothly & evenly.

This has become the “industry standard” for many of the labels we see on commercial products, from shampoo & wine bottles on the grocery store shelf, to pennants & banners at public events.  It also leaves the surface even more prone to picking up a static charge from rolling or unrolling, stacking, sliding, etc.

One of our customers makes a great many labels for all kinds of these commercial products, and uses an EXAIR Gen4 Ionizing Bar immediately prior to the printing operation:

Model 8024 24″ Gen4 Ionizing Bar removes static from Corona treated plastic label film.

EXAIR Corporation has a variety of Static Eliminator Products to fit most any industrial or commercial application.  If you’d like to find out more, give me a call.
