What is the EPA-required evacuation level for recovery or recycling equipment manufactured or imported on or after November 15, 1993?

The correct evacuation level for recovery or recycling equipment that was manufactured or imported on or after November 15, 1993, is 25 mm Hg absolute. This requirement ensures that a significant portion of refrigerant is removed from the refrigerant system, promoting environmental safety and compliance with EPA regulations.

The specified evacuation level helps prevent the release of ozone-depleting substances into the atmosphere and aligns with the goals of the Clean Air Act. Achieving an evacuation level of 25 mm Hg absolute means that the pressure in the system is low enough to minimize the presence of any remaining refrigerant. This standard is an essential part of responsible refrigerant handling practices for technicians, contributing to overall environmental protection efforts.
