Operating a compressed air system can be expensive, with energy costs making up most of the total expense over time. The upside is that a few straightforward changes can boost efficiency, reduce waste, and save you thousands each year.
Here are six proven ways to optimise your compressed air system, from finding leaks to improving the layout, so it keeps running at its best.
Why Efficiency Matters
Compressed air is often called the “fourth utility,” but it is also one of the most expensive to produce. In many industrial facilities, electricity for compressors makes up 70% or more of the system’s total lifetime cost.
Even a small 3 mm leak can waste hundreds of dollars in energy each year. When you add up leaks across an entire plant, it becomes clear why improving compressed air efficiency is so important.
If systems are not optimised, you may face:
· Higher energy bills
· Increased wear on compressors
· Downtime from equipment failures
· Contaminated air is affecting product quality
On the other hand, optimising your system lowers costs, increases reliability, and helps your equipment last longer.
Tip 1: Regular Leak Detection and Repairs
Air leaks quietly drain profits in many facilities. Studies show that poorly maintained systems can lose 20–30% of compressed air to leaks.
Leaks often happen around joints, fittings, and connections. Over time, vibration and corrosion can make these leaks worse.
To fix this, include a leak detection program in your maintenance schedule. This can involve:
· Ultrasonic leak detection surveys
· Routine inspections by trained staff
· Repairing leaks immediately rather than letting them accumulate
For example, one of Sydney’s largest distribution centres worked with Air Energy to upgrade its compressed air system. Just by detecting and repairing leaks, they saw significant energy savings within a few months.
Tip 2: Use the Right Pipe Size
Pipes are often overlooked, but they have a big impact on how well your system works.
· If pipes are too small, they cause high pressure drops and make compressors work harder.
· Pipes that are too large can waste both money and space.
Aluminium air piping systems, like Unipipe, are designed with smooth internal surfaces that maintain consistent airflow with minimal pressure drop. Correct sizing ensures your compressors operate efficiently without unnecessary strain.
At an Australian food production facility, switching to correctly sized aluminium piping improved efficiency and provided clean, contaminant-free air, which was essential for their hygiene standards.
Tip 3: Maintain Compressors and Dryers Properly
Compressors and dryers are central to your system. If they are not maintained properly, efficiency drops quickly.
Key steps include:
· Replacing filters on schedule
· Checking and draining condensate traps
· Inspecting belts and lubrication
· Monitoring dryer performance to prevent moisture carryover
If you neglect maintenance, energy use increases, and equipment lasts less. In mining, where compressors run all day, good maintenance means more reliable operation and fewer expensive breakdowns.
Tip 4: Optimise System Layout (e.g. Ringmains)
The way your system is laid out can make or break efficiency.
· Dead-end layouts often cause uneven pressure and create bottlenecks.
· Ringmains form a loop, which keeps pressure even across the system and reduces pressure drop.
With an optimised layout, you can isolate parts of the pipework for maintenance without stopping the whole plant.
At a regional winery getting ready to grow, we installed a ringmain layout. This gave them the flexibility to expand and kept pressure steady in all production areas.
Tip 5: Monitor Usage with Smart Controls
You can’t manage what you don’t measure.
Smart controls and monitoring systems show how much air you use, when demand is highest, and where energy is wasted.
Some of the benefits include:
· Identifying leaks or unusual consumption early
· Matching compressor output to actual demand
· Reducing idle running time
Modern monitoring systems can connect with facility management software, so procurement and operations teams can see energy use and performance trends.
Tip 6: Train Staff on Best Practices
Even the best system will not work well if staff do not use it properly. Simple changes in how people work can help prevent waste.
Examples include:
· Turning off air tools when not in use
· Using the right fittings for the job
· Reporting leaks promptly
· Avoiding the misuse of compressed air for cleaning or cooling
Training helps make sure your investment in equipment leads to steady efficiency improvements.
The Payoff of a Well-Optimised System
What does optimisation actually achieve?
· Cost savings: Reduced energy bills, fewer leaks, and lower maintenance costs add up to thousands saved each year.
· Improved reliability: Proper layouts, maintenance, and monitoring mean fewer unexpected breakdowns.
· Longer equipment life: Compressors and tools last longer when they’re not under constant strain.
For example, when a logistics operator upgraded their system with Air Energy, they quickly saved money by repairing leaks, improved air quality for their automated equipment, and had fewer maintenance callouts.
Optimising a compressed air system is not a one-time project; it is an ongoing process. The rewards are significant, and the steps are simple.
Compressed Air Is Too Valuable
It is also too costly to ignore inefficiencies. By focusing on leak detection, correct pipe sizing, equipment maintenance, smart layouts, monitoring, and staff training, any facility can optimise its compressed air system.
The result is lower energy costs, better reliability, and a system that pays for itself through efficiency gains year after year.
