Promos, Freebies, and Some Amazing Products

Like many companies, here at EXAIR we generally always have a promotional offering.  These rotate throughout the months and this month is no different.  The current offering involves the EXAIR Cold Gun Aircoolant Systems.

These systems help to reduce cutting fluid use, increase production speeds, increase tool life, and has helped more customers than I know.  One customer in particular is a maintenance worker from a welded tube manufacturer.  This facility had very little amount of downtime permitted due to the high efficiency and high volume of orders.  When a machine went down the maintenance team were in like a trauma team to determine the cause of failure and get it remedied to get the line back up and running. One of the biggest problems they would have is when they would have to dry machine a quick part to get the machine back up and running, this would either ruin tools or they would have to slow down the machining time to get the surface finish and dimensions they truly needed.  After talking with us the team ordered a Single Point Cold Gun Aircoolant System as these parts were generally smaller shafts or machine dogs.

They received the system in and sure enough a machine went down.  The crew went to work and once the part needed was found they got to work on their lathe trying to make a new piece.  The Cold Gun held itself straight to the headstock thanks to the integrated magnet and the flexible single point hose kit routed the cold air straight to the cutting point.  They didn’t have to fill up the liquid tank or setup the mist system on the lathe, they simply turned on the compressed air and let the lathe do the work.  They were able to take what had recently been around a three hour machine job with heavy wear on tooling to a two hour job, no finish pass was needed on the part, and their tools weren’t completely spent by the end of the job.

They got the part back into the machine, made adjustments, and then went to work getting the machine back into production.

Right now, if you would like to try out a Cold Gun Aircoolant System you can order before 12/31/2019 and use the link to order through our promotion in order to receive a free Dual Point Hose Kit with your qualified purchase.

A Brief History of Compressed Air

So where exactly did compressed air come from? How did it become so widely used and where will it go? Both of these are great questions and the answers lie below.

Compressed air can be traced all the way back to the classic bellows that were used to fuel blacksmith fires and forges.  These started as hand pumped bellows, they then scaled up to foot pumped, multiple person pumped, oxen or horse driven and then eventually waterwheel driven.  All of these methods came about due to the demand for more and more compressed air. These bellows did not generate near the amount of air pressure or volume needed for modern day practices yet they worked in the times.  These early bellows pumps would even supply miners with air.

With the evolution of metallurgy and industry these bellows were replaced by wheel driven fans, then steam came about and began generating more industrial sources of power.  The main issue with steam was that it would lose its power over longer runs of pipe due to condensing in the pipes.  Thus the birth of the air compressor was born. One of the largest projects that is noted to first use compressed air was in 1861 during the build of the Mont Cenis Tunnel in Switzerland in which they used compressed air machinery.  From here the constant need and evolution for on-demand compressed air expanded.  The picture below showcases two air compressors from 1896.

Air Compressors from the old days.

The compressors evolved over time from single stage, to two-stage reciprocating, on to compound, rotary-screw compressors, rotary vane, scroll, turbo, and centrifugal compressors with variable frequency drives.  The efficiency of each evolution has continued to increase.  More output for the same amount of input.  Now we see a two-stage compressor, considered old technology, and wonder how the company can get any work done.

All of the technological advances in compressor technology were driven by the demand sides of the compressed air systems.  Companies needed to power more, go further, get more from less, ultimately increase production.  With this constant increase in demand, the supply of compressed air increased and more efficient products for using compressed air began to evolve so the air was used more efficiently.

Enter EXAIR, we evolved the blowoff to meet the increasing demands of industrial companies to get the same amount of work done with less compressed air. We have continually evolved our product offering since 1983.  It all started with just a few typed pages of part numbers and has evolved to a 208 page catalog offering of Intelligent Compressed Air Products® for industry.  We will also continue to evolve our product designs for continued improvement of compressed air usage.  This is all to better help companies retain their resources.

You Don’t Need to Spend Thousands to Optimize Your Compressed Air System

There is no denying it, saving compressed air is a process.  This process often involves some type of energy audit or at the very least an evaluation of something going wrong with production and a way to improve it.  Many programs, consultants, and sales reps will devise a solution for the problem.

Often times the solution is to create a more efficient supply side of the compressed air system. The supply side is essentially everything within the compressor room or located in close proximity to the actual air compressor. While optimizing the supply side can amount to savings, many of these solutions and services can involve great expense, or capital expenditure processes.  These processes can often lead to delays and continued waste until the solution is in place.  What if there was a way to lower compressed air usage, save energy, solve some demand issues on the compressed air system and save some money while the capital expenditure process goes through for the larger scale project.

These solutions are a simple call, chat, email or even fax away. Our Application Engineers are fully equipped to help determine what points of your compressed air demand side can be optimized. The process generally starts with our Six Steps To Compressed Air Optimization.

6 Steps from Catalog

Once the points of use are evaluated the Application Engineer can give an engineered solution to provide some relief to the strain on your compressed air supply side.  For instance, an open copper pipe blow off that is commonly seen within production environments can easily be replaced with a Super Air Nozzle on the end of a Stay Set Hose that will still bend and hold position like the copper pipe does while also saving compressed air, reducing noise level, and putting some capacity back into the supply side of the compressed air system.

Engineered solutions (like EXAIR Intelligent Compressed Air Products) are the efficient, quiet, and safe choice.

One of the key parts to the solutions that we offer here at EXAIR is they all ship same day on orders received by 3 PM ET that are shipping within the USA. To top that off the cost is generally hundreds, rather than thousands (or tens of thousands) of dollars. Well under any level of a capital expenditure and can generally come in as a maintenance purchase or purchased quickly through the supply cribs.  Then, to take this one step further, when the EXAIR solution shows up within days and gets installed EXAIR offers for you to send in the blow off that was replaced and receive a free report on what level of compressed air savings and performance increases you will be seeing and provide a simple ROI for that blow off (though we would also encourage a comparison before a purchase just so you have additional peace of mind).

This amounts to saving compressed air and understanding how much air is being saved, adding capacity back into your supply side which will reduce strain on the air compressor, give the ability to increase production while the capital expenditure for the end solution of controls and higher efficiency on the supply side is approved to then save even more compressed air and energy.

The point is this, savings and efficiency doesn’t have to involve a capital expenditure, if that is the end game for your project that is great! Let EXAIR provide you a solution that you can have in house by the next business day to save money NOW and then put that savings towards another project. No matter the method, it all starts with a call, chat, email or fax.

Air Knife Shim Adjustment can be Key to Successful Applications

On January 2, 1960 Little Anthony & The Imperials appeared on The Dick Clark Saturday Night Beech-Nut Show to sing Shimmy Shimmy Ko Ko Bop. While I wasn’t around at that time, I have heard the song quite a few times and get it stuck in my head more than I have heard it. What does that song and EXAIR have to do with each other? Well, we shimmy shimmy Super Air Knives to dramatically increase or decrease their flow and force.

The stock shim that is assembled in every Super Air Knife is a .002″ (0.05mm) thick. This sets a continuous opening the full length of the knife that drives the performance of the knife. The shim sets the gap height between the cap and the body of the Super Air Knife. If we evaluate a 24″ Super Air Knife with the stock shim installed we could calculate the airflow opening of the knife as the surface area of a rectangle.  To obtain the surface area we take the length of the air knife times the thickness of the shim.  See the example below.

As you can see with the stock .002″ thick shim installed we are actually operating at a surface area opening of 0.048 square inches.  If we were to install the .004″ thick shim into the knife then we would double the height which in turn doubles the surface area, shown below.

This doubling effect will increase the force out of the Super Air Knife when applications require more power.  Thinning out the shim will have the exact opposite effect, if the shim thickness is reduced to .001″ thick then the air consumption and force will be reduced.

Changing the shims out of the Super Air Knives is a fairly simple task as shown in the video below.  Installing a different thickness of shim is a coarse adjustment to the volumetric flow needed for your application.  Then a pressure regulator can be used to fine tune the needed force and flow for the ideal setting to meet your needs, and operate at maximum efficiency for the application.

If you would like to discuss this further or even see what kind of custom thicknesses we can offer on the shims to truly make a tailor fit Super Air Knife for your application, please contact us.

Friction Loss – Pressure Drops – Fitting Restrictions – Why Compressed Air Plumbing Matters

Over the weekend I was working on a car in my driveway and I needed a large volume of air at the far end of the car to try and unplug a clogged sunroof drain line.  Rather than trying to move the car while it was mostly taken apart, I just hooked up another air line extension and started to go to the drain.   Even knowing what I know as an EXAIR Application Engineer about lengths of tubing, air restriction, and fitting restrictions, I went ahead with the quick and easy “fix”.

An example of pressure drop from a compressed air quick disconnect.

I grabbed another 30′ – 3/8″ i.d. air line with 1/4″ quick disconnects (see why this is wrong with this blog) on both end, rather than getting out the 50′ long 1/2″ i.d. air line that I have with proper fittings that then reduce down to a 1/4″NPT at the end to tie into most of my air tools. By doing so I ended up hooking up a Safety Air Gun which then gave a very light puff of air into the tube and the clog in the line went nowhere.  As a matter of fact, it was almost like it laughed because the tubing vibrated as if the clog said, “Pfft I am going nowhere.”

I then, stepped back and evaluated what I had done in a rush to try and get a job done rather than taking the extra five minutes to get the proper air line to do the job.   I then spent 10 minutes putting that hose up and getting out the correct hose.  Then, with a whoosh and a thud the clog was launched into my yard from the clogged drain port and I finished the repairs.

If only I had watched Russ Bowman’s spectacular video on Proper Compressed Air Supply Plumbing the day before. Rather than wasting time with the quick “fix” that cost me more time and didn’t fix anything I should have taken a little more time up front to verify I had properly sized my lines for the job at hand.

If you would like to discuss compressed air plumbing, appropriate line sizes, or insufficient flow on your compressed air system, please contact an EXAIR Application Engineer.

OSHA Safety Standards for Compressed Air

Safety should always be a serious concern within industrial environments.  Walk through any production facility and you should see all kinds of steps taken to give a safe workplace to the operators, contractors, and other team members.  Whether this is through a sign showing PPE required to enter an area, an emergency exit sign, a safe walkway, or machine guards.  Safety has become a standard that should never be lowered and there is good reason for that.

EXAIR designs all of our products to be safe and they meet or exceed OSHA standards that are directed toward compressed air safety.  The first is to ensure that an operator or maintenance worker will not be injured through air impinging their skin should they come into contact with an EXAIR product.   This OSHA standard is 29 CFR1910.242(b) claiming that all point of use compressed air products must be regulated to have less than 30 psig of dead end pressure.   This directive is critical for worker safety and the way many blowoffs skirt by is to cross drill holes in the end of the blowoff.

Cross drilled holes may satisfy the dead end pressure standard but it does not address OSHA’s next important compressed air standard about noise exposure, OSHA standard 29CFR1910.95(a).  The allowable noise level standard combined with 30 psig dead end pressure will render many home made or retail nozzles near useless because few, if any, meet both standards.  Again, EXAIR has engineered and designed our Super Air Nozzles to permit 80 psig inlet pressure and still meet or exceed both of these OSHA standards so that the work can still be done by the operators while remaining safe and retaining their hearing.

For a better explanation and demonstration of how our nozzles meet these standards please see the video below.

While I use nozzles and cross drilled pipes as examples within this blog these safety features are designed into every product that EXAIR offers.  This is due to the fact that OSHA, NIOSH, and the CDC do not delineate between a blow gun, blow off within a machine, or even a Cabinet Cooler System.  If the device is powered by compressed air then the two key OSHA standard are in effect due to the inherit dangers of compressed air.

I encourage you now to walk through your facility and try to listen or spot compressed air points of use within your facility.  Then, I ask you to call, chat, e-mail, or tweet an Application Engineer here at EXAIR and let us help you determine the most efficient and safest product to get the work done.
