Most common components are pipes, hoses, fittings, valves, and connectors.
Everything you need to know for perfect leak management
Are you wondering why your system is losing pressure, or why your energy costs are suddenly increasing? That slight hissing sound or drop in performance could indicate a hidden leak (a small problem that can have big consequences!).
In this article, we explore how to spot the common signs of leaks, where they usually occur (think joints, pipes and fittings) and the tools, such as ultrasonic detectors, that make them easier to find.
We'll also discuss simple solutions, smart material choices, and preventive tips to help you avoid future breakdowns. No matter where your installation is located, this article provides clear answers and solutions to maintain your system's efficiency and reduce your costs.
Introduction
Compressed air systems are essential to the operation of businesses and are therefore a valuable ally in their productivity and sustainability. However, problems can sometimes arise and prevent them from functioning properly. Leaks are one such cause, and their impact is quite significant (energy losses, increased operating costs and reduced system performance). Throughout this article, we'll explore the causes, detection methods, repair techniques and prevention strategies for compressed air leaks, so that you have all the information you need to maintain an efficient and cost-effective system.
Why Addressing Compressed Air Leaks is Crucial
It is imperative to counteract the impact of leaks for several reasons.
The first is the direct impact on the energy efficiency of your business. Indeed, leaks can cause a 20 to 30% loss in compressor efficiency, which translates into increased energy consumption and costs.
Furthermore, increased energy consumption translates into higher operating expenses, which will directly affect a business's financial results.
Beyond the economic and energy impact, in general, leaks in your installation will cause pressure drops, directly impacting on the overall performance of your system.
Common Causes of Compressed Air Leaks
Now, let's explore the various factors that can lead to leaks in your system:
- Wear and Tear: Over time, components such as hoses, tubing, and pipework can degrade, leading to leaks.
- Corrosion: Exposure to moisture and contaminants can cause corrosion in piping systems.
- Improper Installation: Incorrect installation of components can create weak points prone to leakage.
Detecting Compressed Air Leaks
Once the potential causes are known, methods must be chosen to correctly identify the leaks.
To begin with, a simple but effective method is to visually inspect the system for signs of leaks, such as oil residue, air pockets, unusual noises (whistling or hissing indicating a leak).
It's also possible to use ultrasonic leak detectors, which are advanced tools that can detect the high-frequency sounds associated with leaks. These devices are equipped with:
• Audio filters: to isolate leak sounds from background noise.
• Microphones: to pick up the sound of leaks.
• Amplifiers: to improve detection capability.
• Visual indicators: to pinpoint the location of leaks.
Finally, you can also perform pressure drop tests, which involve closing the supply valve and observing the pressure gauge. So, if the pressure drops over time, this indicates a leak in the system.
Leak detection
Repairing Compressed Air Leaks
Once leaks have been detected, immediate action must be taken! Here are some common repair techniques:
- Replace worn components such as seals, gaskets, pipes and fittings.
- Ensure that all fittings are properly tightened to eliminate weak points that could leak.
- Choose high-quality piping materials, such as stainless steel or aluminium, to prevent corrosion and premature wear.
Preventing Compressed Air Leaks
Repairing is good, but prevention is even better!
We recommend that you carry out regular maintenance checks to identify and address potential sources of leaks before they become major problems.
Of course, quality is essential. We advise you to invest in modern, high-quality air networks to reduce the risk of corrosion and wear and tear and ensure long-term durability.
In addition, pneumatic audits are also available to quickly detect hidden leaks and provide concrete recommendations for improving system performance. Our audit service offers a comprehensive analysis to minimise energy waste and reduce operating costs.
Conclusion
Leaks are frequent issues that should not be disregarded if you wish to preserve productivity and prevent energy waste. Therefore, by detecting and repairing leaks promptly, and implementing preventive measures, businesses can ensure smooth operation and avoid unnecessary expenses.

Frequently Asked Questions
Oil leaks can be identified by checking for oil residue on the compressor body, monitoring the oil level, looking for oil puddles on the floor, listening to unusual noises, and inspecting seals, hoses, and connections for wear and tear.
They mainly develop in seals, gaskets, hose connections, fittings, pistons, valves, and internal oil components.
The standard process starts with locating the leak, safely relieving pressure, cleaning the area, then replacing worn seals and gaskets, tightening connections, and finally, testing for leaks and adjusting oil levels.
