With nearly every factory worldwide having a compressor and millions of air tools being used daily, Exhausted Air Recycling System (E.A.R.S.) was developed to solve the problem of the wasted air exhausted from these tools. By returning this air to the compressor E.A.R.S. has the ability to:

  • Reduce tool noise
  • Reduce airborne contaminants
  • Decrease power consumption
  • Increase the compressors volumetric output
  • Extend the life of the compressor and the air tools


E.A.R.S. requires the air tools to have their exhausts ducted back to the compressor which is fitted with a manifold to accept this air.
By capturing the exhausted air at the tool all noise and contaminants normally ejected next to the user are sent back to the compressor. This means exhaust noise is significantly reduced and all tool lubrication oil or foreign matter traveling in this air is also taken away. Additionally there is no exhaust air blowing dust or other matter around the workshop, ensuring a cleaner and far quieter work environment.

Once the system is in operation E.A.R.S. can effectively become closed loop, with the compressor recompressing and returning the same air exhausted from the tool.
At this stage the compressor is no longer drawing in ambient air and as such no moisture from humidity is being added to the system. The return air is also at a higher than atmospheric pressure so the compressor needs to do less work to compress this to the desired pressure and thus less heat is generated by the compressor and less heat is added to the air. The reduction in temperature and moisture has a significant effect on increasing both the compressor and the tool life.

The compressor also uses less power as a result of the pressure & flow staying near constant in this cycle and thus the recovery time for the compressor to return to its shut off pressure is reduced. There is also a power saving as the E.A.R.S. fitted compressor can maintain a higher flow rate, equivalent to that of a compressor fitted with a larger and more power consuming motor.

The benefits of E.A.R.S. are therefore seen physically by the operator as well as financially by the owner/company.

For years the pneumatic industry has been dominated by the mentality that certain tools & equipment can only be run by certain sized compressors. This in turn has generated the mindset that if you want to run bigger tools or more of them that you will need a bigger compressor.
Further we seem to be been happy to accept that the air that we are using energy to compress & send to our tools is simply no longer needed after powering the tools and can be wasted without further thought.

Long has it been since the pneumatic industry has encountered a technological break through, nor even a significant advancement, and this has added to the one eyed frame of mind. Manufacturers, distributors & operators have become complacent with the apparent wasted air and even more surprisingly are oblivious to the extremely high noise levels and environmental contaminants  

being exhausted near the end user. Filtering and baffling in the tool was introduced some time ago but these are no where near sufficient and quickly become soaked in the wasted air contaminants. The tool then becomes less efficient due to the increased back pressure and the contaminants are again released near the operator.
