Why Lowering System Pressure Saves Energy

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.
