VEVOR 30 lb refrigerant recovery tank with a small amount of nitrogen is often used to recover refrigerant for household cars, refrigerators, air conditioners, etc. What is the gas filled in the refrigerant recovery tank?.

I also like the fact it has a port to put a pressure transducer on it, which helps with diagnosing issues on systems that use transducers to increase speed on ecm condenser fan
