Evacuation Rates - the "CFM Wars": It's true! The capacity of a standard 1/4"ID hose is limited to 3/4 (0.75) CFM. And that's only if you remove the valve core depressors from your hoses AND Schrader valve cores from the system's high and low side access valves. Thus, evacuating from both high and low sides, you'll max out at approximately 1.5CFM. Standard 1/4" charging hoses are also not designed for vacuum applications, so much as charging & testing.
