All vacuum pumps below are with 2 stages and are compatibles for CFC's, HFC's and HCFC's. Most of compressor manufacturers advise that systems charge with HFC's must be evacuated down to 0.5 mbar (400 µ). For safety reason, a R134a system must be evacuated down to 0.25 mbar (190µ). When a system is evacuated at 0.5 mbar (400µ), we can be sure that there is no moisture or other gases and can be accepted tight.
