• Pressure sizing – Identify minimum process pressure and add cumulative piping, dryer, and filter losses
  • Discharge target – Set compressor discharge pressure = process pressure + system losses + margin
  • Energy impact – Each 1 bar (14.5 psi) pressure increase demands ~7–8% more motor energy
  • Optimization rule – Avoid over-pressurizing “just in case” by utilizing regulation and localized zoning
