Reducing air leaks is the single most important energy-saving measure that can be performed. The leak rate on an unmanaged compressed air system can be as much as 40% of the output.

Compressed air leaks also lead to additional costs through:

  • Fluctuating system pressure, which can cause air tools and other air-operated equipment to function less efficiently — potentially stalling and affecting production.
  • Reduced service life and increased maintenance of equipment due to unnecessary compressor cycling and running time.
  • Excess compressor capacity. The sources of leakage are numerous, but the most frequent causes are:
    • Manual condensate drain valves left open.
    • Shut-off valves left open.
    • Leaking hoses, couplings, pipes and pipe joints.
    • Leaking pressure regulators.
    • Air-using equipment left in operation when not needed.

Identifying and Measuring Leaks

There are a number of ways for detecting leaks. Handheld ultrasonic leak detectors provide an effective method of detecting leaks against background noise without having to stop production.

Here at UAP, we offer a number of leak detection and repair programmes to keep your leak rate at a manageable level. From quick locate and tag plans to complete ASA reports we can accurately calculate your sites energy wastage through leaks.
