Steps to Find Compressed Air Leaks in your Facility

The Second Step to optimize your compressed air system is to Find and fix leaks in your compressed air system. The reason leaks are important to find and fix is because they can account for 20-30% of a compressors total output. A compressed air leak fixing process can save 10-20% of that lost volume.

Unintentional leaks will result in increased maintenance issues and can be found in any part of a compressed air system. Leaks can be found at a poorly sealed fitting, quick disconnects and even right through old or poorly maintained supply piping. Good practice will be to develop an ongoing leak detection program.

The critical steps needed for an effective leak detection program are as follows:

  1. Get a foundation (baseline) for your compressed air use so you have something to compare once you begin eliminating leaks. This will allow you to quantify the savings.
  2. Estimate how much air you are currently losing to air leaks. This can be done by using one of two methods.
    • Load/Unload systems, where T= Time fully loaded and t=Time fully unloaded:
        • Leakage percent = T x 100
          ——
          (T + t)
    • Systems with other controls where V=cubic feet, P1 and P2=PSIG, and T=minutes
        • Leakage = V x (P1-P2) x 1.25
          ————–
          T x 14.7
  3. Know your cost of compressed air so you can provide effectiveness of the leak fixing process.
  4. Find, Document and Fix the leaks. Start by fixing the worst offenders, fix the largest leaks. Document both the leaks found and the leaks fixed which can help illustrate problem areas or repeat offenders, which could indicate other problems within the system.
  5. Compare the baseline to your final results.
  6. Repeat. We know you didn’t want to hear this but it will be necessary to continue an efficient compressed air system in your plant.

EXAIR has a tool to assist you in finding these leaks throughout your facility, the Ultrasonic Leak Detector. Check one of our other Blogs here, to see how it works!
