Innovation is often born of necessity, and sometimes the result is spectacular. Such is the case of this revolutionary new system: “Exhausted Air Recycling System” or EARS
EARS was created out of frustration by Chris Bosua in Australia, as he tried to make a pneumatic manufacturing machine work with an air compressor that was simply too small for the job. With a background in mechanical engineering and a bit of Aussie common sense, Chris realized that the problem was waste – all that energy used to create the compressed air was wasted out the exhaust of the pneumatic tool. “Why not create a closed loop system and just send that air right back to the compressor – just like a hydraulic tool works?” he asked himself. After a few tries assembling a few bits in his workshop and creating a special manifold, Chris hit it just right, making a system that converted an ordinary compressor into a compressor capable of almost double the capacity, and EARS was born.
Imagine an invention that literally doubles the capacity of an ordinary air compressor— this alone is spectacular, but the benefits did not stop there. With the whole system up and working, the unforeseen benefits started to reveal themselves. The first and most obvious was a dramatic reduction in noise. The pneumatic drills used in the machine had a decibel level of 89db prior to EARS, after the conversion the drills were virtually silent, with a decibel level of just 67db – or the difference* between a common lawn mower and a sewing machine!
As testing and use continued, the other benefits became obvious:
The return of pressurized air into the inlet of the compressor had a dramatic effect on energy use.
Under continuous use, energy consumption dropped over 40% -- not only was this invention functional, it would pay for itself over time in the shop energy bills.
The closed loop air was much drier (up to 70% as the compressor no longer needed to pull in ambient air) and cooler – this extended the life of the tools, hoses and the air compressor.
No longer did the air tools emit oil vapor and other harmful exhaust into the atmosphere of the shop. Since the tool exhaust was returning via a hose to the compressor, there was no longer the dust and debris blown about the shop from the exhaust of the tools.
The results were so spectacular that the next step was to develop simple retrofit kits for all common applications with air compressors – arrange for proper patents and begin to share this invention with the world. As the word spread, so did the recognition and acknowledgement of the potential for this invention. In the first 6 months, EARS has won competitions like the ABC Television show “The New Inventors”, was a finalist for the “Next Big Thing” award, plus submitted for recognition as a winner of the prestigious Motor Magazine “Top 20 Tool Award”.
* Decibel ratings are logarithmic. A 10 db increase is 10 times louder. The change from 67 to 89 db means the original tool was 120 times louder than the EARS tool.
