Is your Compressed Air Piping leak free?

Compressed air system leaks are indeed a big source of energy waste. Leakage in piping systems have been shown to exhibit leaks of up to 25 percent of the total energy costs. Addressing leaks is one of the first maintenance steps a facility can take to reduce energy costs.

Your distribution system is likely to have leaks if you experience the following:

You may notice these symptoms and attribute them to poor compressor performance, but the most likely culprit is air leaks.

How to Fix Air Leaks

Addressing air leaks is one of the first steps you can take in reducing energy costs. Most experts agree that the use of an ultrasonic acoustic detector is the best way to detect air leaks. This device recognises the high frequency hissing sounds associated with air leaks and uses a variety of visual and audio indicator to identify the leaks' location.

Addressing the leaks:

  1. Leaks occur most often at joints and connections. Stopping leaks can be as simple as tightening a connection or as complex as replacing faulty equipment such as couplings, fittings, pipe sections, hoses, drains and traps.
  2. In many cases, leaks are caused by bad or improperly applied thread sealant, which can be fixed by properly installing equipment with the appropriate thread sealant.
  3. Another source of leaks can come from non-operating equipment. Equipment that's no longer is use should be isolated with a valve in the distribution system.
  4. Lowering the demand air pressure of the compressed air system can also reduce leaks. The lower the pressure differential across an orifice or leak, the lower the rate of flow, which equals a decreased leakage rate. 

Once leaks have been repaired, the compressor control system should be re-evaluated to realise the total savings potential.

Just like any other equipment, a compressed air installation also requires the necessary maintenance work during its entire lifespan. Even though maintenance costs are only about 5 to 10% of a machine's annual operating costs, failure to budget for maintenance can have potentially disastrous consequences.


The air dyer is one of the most ignored cooler in the system. A dirty condenser will cause water in the lines, or worse it will cause complete dryer failure.


Using nitrogen is not about fully replacing CO2, but it can reduce their consumption of CO2 by close to 70%. Using nitrogen is about sustainability. Creating your own nitrogen is easy and will reduce the use of a greenhouse gas, which is better for the environment. It will also save you money as early as month one adding that savings to your bottom line.


A question that is occasionally asked by our customers to Ash Air is 'what is the cost of compressed air?'  This article looks at the product costs involved with compressed air, as well as minimising the energy cost of compressors and cost allocation. When looking at these factors, we need to realise what causes dropped efficiency of your compressor, leading to increased costs of compressed air.
