Compressed air installation of more than 5 years old has an average 20% of air leakage. Air leaks are a big waste of energy, but easy to ignore. In a typical industrial plant, compressed air accounts for up to 40% of the total electricity bill. Any leakage generated from compressed air will cause a huge amount on your bill.
What is Air Leakage?
What is Air Leakage?
When an extra or unwanted airflow breaks through a vessel, pipe, or sealed container, it is called compressed air leakage. Generally, air leakage happens from inside out – a flow of air from high pressure to low pressure – but may also occur from outside when ambient air flows into a vacuum vessel.
Either overlooked or identified much later, air leaks can be one of the biggest contributors to energy wastage at your industrial facility. For instance, compressed air systems with five-year-old piping have been observed to cause leakage of up to 25%. In terms of monetary loss, leakages from a 3 mm orifice size at 7 bar pressure may cost over ₹1.50 Lacs a year.
Therefore, addressing leaks is critical for reducing energy costs and maintaining sustainable production in your unit.
Do you know how much air leaks cost your company?
| Orifice Size mm | cfm loss | kW Wasted | * Cost of air leakage (Rs/Year) |
| 0.8 | 1.2 | 0.2 | 11,200.00 |
| 1.6 | 4.8 | 0.8 | 44,800.00 |
| 3.1 | 18 | 3 | 1,68,000.00 |
| 6.4 | 72 | 12 | 6,72,000.00 |
Why does an Air Leakage occur?
Air leakages are one of the operating concerns of using compressed air systems. But timely leak tests and scheduled maintenance can help avoid compressed air leak and ensure the longevity of your compressor. Here are some reasons why air leakages happen.
1. Moisture laden air
Rich in moisture content, untreated or semi-treated air may enter the air network and begin damaging the internal parts of the pipes. This reason is by far the most common reason for air leaks.
2. Unfit material selection
Wrong material selection for piping your compressed air system is also a reason that leads to erosion of the pipes. For example, bare CS pipes can result in surface corrosion.
3. Loose joints and sealings
Undersized pipes and loose joints can also generate a high velocity, leading to pipe corrosion and subsequent air leakage.

What is an Air Leak Test and why conduct it?
Conducting an air leak test at the right time can prevent the leakage issues from affecting the final user points. To put it simply, an air leaking test is an evaluative method to scan for leakage issues and analyze pressure in your air compressor. Following are the benefits of performing an air leak test:
- Leak standards are quantified
- Product efficiency is optimized
- Time and work saving with automation
- Operational and energy costs are reduced
- Measurement data ensure product improvement

What are some Air Leak Testing methods?
Most of the time, users are not aware of the air leakage from their compressed air systems. By the time they detect the leakages, a lot of money and energy have already been lost. Although some leaks can just be found by listening, major ones are either inaudible or inaccessible.
The most common practices in the industry to identify air leakages are:
The most widely used approach is the ultrasound leak detection method for faster detection and prevention of air leakages. Since a leak site creates a turbulent flow with ultrasound components, ultrasound detectors can identify leakages no matter how noisy the environment is.
Should you want to identify and fix inaccessible leaks in your unit, count on Atlas Copco experts and solutions.
A quick fix solution for long term results
To prevent energy loss and ensure optimal performance of your air compressor system, Atlas Copco brings you a complete compressed air leak check program, providing a leakage identification test with ultrasonic leak detector camera at the site without interrupting your production.
Our experience engineer will trace the complete compressed air line network to find out the leakage points, quantify the leaks in terms of volume flow to understand the severity of leaks and list the leakages with photographs and leak tag. At the end of the Air Leak Check program, you will receive a detailed report of in-depth evaluation of problems along with recommendations for leak repair, and save up to 30% of energy immediately by closing the energy gap.
