Running compressed air at higher pressure than needed is a common and costly mistake. Reducing pressure is one of the fastest energy wins available.
The Energy Link
- Every 1 bar of extra pressure adds roughly 7% energy.
- Higher pressure also increases leaks.
- Most plants can run 1–2 bar lower without problems.
Finding the Right Pressure
- Check the minimum pressure each process needs.
- Account for pressure drop through piping and filters.
- Test the system at a lower setpoint gradually.
Making It Stick
- Reduce the compressor setpoint and deadband.
- Fix restrictions that force higher pressure.
- Use local storage for high-flow points.
How much can lowering pressure save?
Dropping from 8 bar to 7 bar can save roughly 7% of compressed air energy, with more from reduced leaks.
