Compressed air is often described as the fourth utility in industry, alongside electricity, gas and water. However, unlike other utilities, compressed air is frequently one of the least monitored and most inefficient systems within a manufacturing or production facility.
For many businesses, a compressed air system has been running in the background for years with little understanding of how efficiently it is operating. The result? Higher electricity bills, unnecessary wear on equipment, reduced reliability and expensive compressed air leaks that can go unnoticed for months or even years.
The good news is that there is a straightforward solution.

What Is Compressed Air Data Logging?
Compressed air data logging is the process of monitoring your compressed air system over a period of time using specialist recording equipment. Rather than relying on a snapshot of how your compressors are performing, data logging provides a detailed picture of how your system behaves throughout normal operating conditions.
A typical data logging exercise can record:
Air demand throughout the day
System pressure fluctuations
Compressor load and unload cycles
Energy consumption
Running hours
Peak demand periods
Overnight or weekend air usage
Compressor sequencing performance
This information allows engineers to identify hidden inefficiencies and recommend practical improvements that deliver measurable cost savings.
Why Is Data Logging So Important?
Many businesses assume their compressed air system is operating efficiently simply because it is producing air. Unfortunately, this is often not the case.
Compressed air is one of the most expensive forms of energy used within industry. In many cases, over 70% of the lifetime cost of a compressor is electricity, not the initial purchase price.
Without accurate monitoring, it is impossible to know whether your system is operating efficiently.
Data logging helps answer critical questions such as:
Is my compressor correctly sized?
Am I wasting energy during periods of low demand?
Are multiple compressors fighting each other?
Is my system pressure set higher than necessary?
Do I have significant compressed air leaks?
Could I reduce my electricity costs with better compressor control?
How Data Logging Saves Money
1. Identifying Compressed Air Leaks
Even a small compressed air leak can cost hundreds or thousands of pounds each year.
Many facilities lose between 20% and 30% of the compressed air they generate through leaks.
Data logging can identify unusual overnight air demand when production has stopped, often providing the first indication that leaks are costing your business money.
2. Reducing Electricity Consumption
Compressors are significant consumers of electrical power.
If compressors are constantly loading and unloading unnecessarily, operating outside their most efficient range or running at excessive pressures, electricity costs increase dramatically.
Data logging enables engineers to optimise compressor operation and reduce unnecessary energy usage.
3. Correct Compressor Sizing
Many businesses have compressors that are significantly oversized for their actual demand.
An oversized compressor can spend much of its life unloaded while still consuming substantial amounts of electricity.
Data logging provides real demand profiles, helping businesses select equipment that matches actual production requirements.
4. Optimising Multiple Compressor Installations
Where multiple compressors are installed, poor sequencing often results in inefficient operation.
By analysing system demand over time, engineers can recommend improved compressor sequencing or control systems that ensure compressors operate at maximum efficiency.
5. Reducing Downtime
Data logging highlights pressure drops, unusual operating patterns and equipment that may be approaching failure.
Identifying these issues before they develop into breakdowns helps improve reliability and reduces costly production downtime.
The Return on Investment
Many businesses are surprised by how quickly compressed air improvements pay for themselves.
Typical benefits include:
Lower electricity bills
Reduced carbon emissions
Improved system reliability
Extended compressor life
Reduced maintenance costs
Better production efficiency
Increased system capacity without purchasing new equipment
In many cases, the savings identified through a professional compressed air data logging survey can repay the cost of improvements within a relatively short period.
