Benchmarking shows how your compressed air system performs against similar plants. Specific energy is the key metric for comparison.
The Key Metric
- Specific energy in kW per m³/min or kWh per m³.
- Measure power and flow under normal load.
- Compare at the same working pressure.
How to Benchmark
- Log energy and flow over representative periods.
- Compare with manufacturers’ published data.
- Track trends after changes.
Acting on Results
- Investigate when specific energy is high.
- Set targets and review progress.
- Use the data to justify upgrades.
What is a good specific energy for a screw compressor?
Around 6–7 kW per m³/min at 7–8 bar for Grade-1 machines, depending on conditions.
