A few weeks ago I was on vacation with my family. My wife and I had taken our three daughters to Columbus, OH for three days after camping in a tent for a few days. One of the focal points to the trip was COSI, the Center of Science and Industry. In case you live anywhere near Columbus, OH and have not heard of how amazing this interactive museum is, you should definitely check it out. This isn’t your normal museum.
While the Mythic Creatures exhibit and the Jim Henson exhibit were both absolutely amazing for my 9, 6 and 4 year old daughters, it was also entertaining for my wife and myself. Now you may be asking what does this interactive science place and trip with kids have to do with EXAIR.
Well, while my daughters and I were watching this enormous pendulum that knocks ball bearings off boxes every few minutes I could hear that all too familiar, gentle sound of compressed air blowing every now and then. I couldn’t however see where the noise was coming from.
As we wandered through the different sections I saw several examples of compressed air use but none were the exact sound or display I had heard. When we were walking through the Space exhibit just above where the pendulum was located and that gentle sound was getting closer. All of a sudden I saw it. Next thing I know I look up and my 6 year old was using a joystick to control a scaled down Lunar Lander propelling it in circles. This was where the sound was coming from.
While I was amazed by this interactive piece I could tell they were using compressed air and I was curious as to how it was working. That’s when I noticed the distinct design of our Nano Super Air Nozzle on the bottom of the Lander. Here’s a close up picture, well as close as the handrail would allow me to get without over reaching.
The interesting part to this is how this setup gives an idea of the amount of thrust given off by a nozzle that only consumes 8.3 SCFM of compressed air when powered at 80 psig inlet pressure. These nozzles can easily be fitted to blast debris or moisture out of small pockets or hard to reach areas. They also can be used to help direct product that may be getting diverted to a new conveyor. And, obviously, they can be used to propel scale models of lunar landers.
If you would like to discuss any application for point of use compressed air, and I do mean ANY, give us a call. If I can’t help with the application we will at the very least do our best to send you in the right direction.
From pneumatic hand tools like impact wrenches or nail guns to larger scale industrial applications like stamping presses, the use of compressed air can be found in almost any industry. In fact, it is often referred to as a “fourth utility” next to water, gas and electric.
Take for example in construction, workers will use a pneumatic riveter to join steel framing because of the power generated by the tool over an electrically powered device, not to mention it provides for a safer operation by removing an electrical hazard. Many companies use compressed air operated diaphragm pumps or air motor driven pumps to move expensive or viscous liquid from one location to another. These types of pumps are self priming drawing the liquid in and provide positive displacement meaning they fill and empty the liquid chamber with the same amount of liquid through a common inlet and outlet.
Amusement parks have used compressed air in some capacity in the operation of thrill rides like roller coasters or to enhance the effect of certain attractions. Compressed air can be found in hospitals where it is used for specialized breathing treatments or to power surgical instruments in an operating room. Educational facilities use compressed air for laboratory testing. You can even find compressed air in the tires on your car. Basically, when you think about it, compressed air is being used just about anywhere.
Here at EXAIR, we manufacture Intelligent Compressed Air Products to help improve the efficiency in a wide variety of industrial operations. Whether you are looking to coat a surface with an atomized mist of liquid, conserve compressed air use and energy, cool an electrical enclosure, convey parts or dry material from one location to another or clean a conveyor belt or web, chances are we have a product that will fit your specific need.

Recently a customer called in to EXAIR to discuss a static issue in a stretch wrap process in the plant. Stretch wrap is a highly stretchable plastic film. The elastic recovery keeps the wrapped load tightly bound. The most common stretch wrap material is a linear low-density polyethylene or LLDPE. The combination of the stretching of the plastic film and the sliding of the film on the cardboard boxes as it is being wrapped causes a build up of static. This static can cause serious havoc and issues in the process including personnel shocks, zapping counters and other sensors causing failures, and preventing marking systems from delivering good information on to the stratch wrap.
The discussion started with minimum and maximum load sizes and how to design a system that would work with all configurations and be as flexible as possible. We spoke of dimensions and where we could we could mount on 3 sides, and so forth.
Then came the question that we invariably get to and that is ‘what issue does the static cause and how does it affect the rest of the process?’ The answer here simple, ‘an operator has to write a code number on the side and affix a label, and in doing so, receives a shock.’ When it was determined that only a small section of one side of the load needed to be treated, the solution was simple. We proposed an 18″ Ionizing Bar and Power Supply. Because the machine had a fixed datum, all loads would pass within 1-2″ of a vertically installed Ionizing Bar, so no adjustment is needed for different load sizes.
The Ionizing Bar quickly dissipates a strong static charge as shown in the chart below.
EXAIR offers many systems for total static control. When static is a problem on moving webs, sheet stock, three dimensional parts, extrusions or packaging, EXAIR has a solution.
To discuss your application and how an EXAIR Static Eliminator would help out, feel free to contact EXAIR and one our Application Engineers can help you determine the best solution.
