Hydraulics & Pneumatics Magazine September 2025

Pneumatic systems may look simple but their behaviour can be subtle. Maintenance personnel need the skills to interpret sensor data and to understand how different parts of the system interact. A pressure drop may not be caused by a leak but by an undersized pipe or a sticking valve. Without the ability to diagnose correctly, investment in monitoring will not deliver its full benefit. Many suppliers now provide training alongside equipment to help engineers make sense of the information available. Building this knowledge base within the workforce reduces reliance on external contractors and allows quicker response to issues. A further solution lies in the design stage. When new systems are specified, provisions for maintenance and monitoring can be incorporated from the outset. For example, including test points and isolation valves allows sections of the network to be checked or repaired without shutting down an entire plant. Selecting components with built-in diagnostics simplifies faultfinding. Choosing piping materials that resist corrosion reduces contamination risk and prolongs service intervals. Thoughtful design does not eliminate the need for maintenance, but it makes the process more straightforward and less disruptive. There is also an environmental dimension. In a context where industry is under pressure to cut carbon emissions, inefficient compressed air systems are a significant liability. Every unit of wasted air represents electricity consumed at the compressor. Reducing leaks and optimising control not only cuts operating costs but also contributes to sustainability targets. This alignment between financial and environmental goals strengthens the case for investment in monitoring and proactive care. Cultural factors play a part as well. In some factories, compressed air is treated as a free resource because its cost is not easily visible at the point of use. Operators may leave tools connected and air lines pressurised even when equipment is idle. Encouraging awareness among staff about the value of compressed air and the consequences of waste can support the technical measures. Posters, training sessions and internal campaigns are inexpensive but can foster a mindset where everyone contributes to efficiency.

Pneumatic systems can feed into wider factory management systems, allowing data from compressors, air lines and end-use devices to be viewed alongside other utilities. This creates a more comprehensive picture of plant performance and enables managers to make decisions based on evidence rather than assumption. The concept of the smart factory is often associated with high-profile technologies, but in practice much of the value comes from making long-established utilities like compressed air more transparent and efficient. The maintenance and monitoring of pneumatic systems in the UK is moving from a reactive to a proactive discipline. Preventive maintenance provides a foundation, while monitoring technologies and predictive strategies allow resources to be used more effectively. Training, design considerations and cultural awareness all reinforce the process. The result is not only lower costs and improved reliability but also a contribution to environmental goals. By treating compressed air with the same seriousness as electricity or water, industry can unlock value that has long been hidden in plain sight.
