HVAC Vacuum Micron Reference

In HVAC refrigeration service, micron measurement indicates the depth of vacuum achieved during system evacuation. A lower micron reading means a deeper vacuum and better moisture removal.

  • 500 microns or below: Good evacuation level
  • 300 microns or below: Deep vacuum
  • 100 microns or below: Professional refrigeration standard
