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.

EXAIR’s Efficiency Lab is now the “award-winning Efficiency Lab”. Thank you to Environmental Protection Magazine for recognizing the value and importance of this EXAIR service.
I have blogged about this many times and we continue to help customers by using our free Efficiency Lab service that EXAIR provides to customers throughout the USA. The EXAIR Efficiency Lab allows customers to send in their existing blow off device and we will test it for compressed air consumption, sound level, and force. Ideally we try to take these measurements at the same operating pressure that is being supplied in the field so that we can compare it to an EXAIR product and offer the customer the best solution, the safest solution, and an engineered solution capable of saving them money through air savings and effectiveness.
Here is a recent example of a product sent in by a customer concerned with compressed air consumption and safety of their people. The hose they sent in was actually designed to be used with liquid coolants and was a very large consumer of compressed air.
The hose shown above was being used at 40 psig inlet pressure. The device is not OSHA compliant for dead end pressure, nor does it meet or exceed the OSHA standard for allowable noise level exposure. The hose was utilizing 84.64 SCFM of compressed air and was giving off 100.1 dBA of sound.
As seen in the chart above, an employee is only permitted to work in the surrounding area for 2 hours a day when exposed to this noise level. The amount of force that the nozzle gave off was far more than what was needed to blow chips and fines off the part. The EXAIR solution was a model 1002-9230 – Safety air Nozzle w/ 30″ Stay Set Hose.
The EXAIR products were operated at line pressure of 80 psig which means they utilized 17 SCFM of compressed air and gave off a sound level of 80 dBA. On top of saving over 67 SCFM per nozzle and reducing the noise level to below OSHA standard, the EXAIR engineered solution also meets or exceeds the OSHA standard for 30 psig dead end pressure. In total this customer has replaced 8 of these inefficient lines and is saving 541 SCFM of compressed air each time they activate the part blowoff.
If you would like to find out more about the EXAIR Efficiency Lab, contact an Application Engineer.
We look forward to testing your blow off and being able to recommend a safe, efficient, engineered solution.

My favorite class in college was a robotics course taught by a brilliant professor who invented the first laser eye surgery chair. He was incredibly thorough, had more knowledge of robotics and the robotics industry than anyone I’ve met since, and in general was a pretty cool guy. The robots in class were basic pick-and-place ABB devices that we would program to move, count, stack, or perform any possible function within the work envelope. I’ve seen plenty of robots since then, as recently as this afternoon when I watched an engineer plug in a 3D printed robot to his laptop to perform a simple pick-and-place function. But for some reason, whenever I work through a robotics application I go back to the same class where we would code and recode the machines until the operations were perfect.
Recently, I worked through an application in which robotic arms were pulling gears out of a hobbing process. During the transfer, an additional blow off was needed to remove cutting oil so that it didn’t fall on to walkways and pose a danger to personnel. The end user in this case wanted to know whether it would be possible to pass the gear/arm assembly through an air curtain to remove the oil and remove the hazard.
We came to the design above, which uses two Super Air Knives to create opposing blow off forces for the gear/arm assembly. The gears pass through this blow off after being removed from the previous stage in the process, and the oil which is blown off of the gears is fed right back into the previous stage. This not only allows for a high force blow off, but saves wasted cutting oil.
