Page 22: The Importance Of Deep Vacuum
THE IMPORTANCE OF DEEP VACUUM The purpose of a vacuum pump is to remove moisture and air from an A/C-R system. Modern systems are built tighter and charges are more critical. That means these systems have a greater sensitivity to moisture and other contaminants, making thorough evacuation more important than ever before. -
