Evacuating a automobile AC system is the method of eradicating all the refrigerant from the system. That is needed when the system is being serviced or repaired, or when the refrigerant is being changed. Evacuating the system removes all the outdated refrigerant, together with any contaminants, in order that the system might be charged with new refrigerant.
There are two major strategies for evacuating a automobile AC system: utilizing a vacuum pump or utilizing a refrigerant restoration machine. A vacuum pump is a tool that creates a vacuum within the AC system, which pulls out the refrigerant. A refrigerant restoration machine is a extra specialised piece of kit that not solely evacuates the refrigerant but in addition recovers it in order that it may be reused.
