Finding and Fixing Leaks | Compressed Air Best Practices

Finding & Fixing Leaks and Establishing A Leak Prevention ProgramEstimating Amount of LeakageLeak DetectionHow to Fix LeaksEstablishing A Leak Prevention ProgramLeaks can be a significant source of wasted energy in an industrial compressed air system, sometimes wasting 20-30% of a compressoroutput. A typical plant that has not been well maintained will likely have a leak rate equal to 20% of total compressed air production capacity. On the other hand, proactive leak detection and repair can reduce leaks to less than 10% of compressor output. In addition to being a source of wasted energy, leaks can also contribute to other operating losses.
