Which device is used to create a vacuum in a refrigeration recovery process?

Explanation:
Pulled vacuum inside the refrigeration system is achieved with a vacuum pump. By lowering the pressure inside the system, it allows air, non-condensables, and moisture to be drawn out and vented. Evacuating before charging helps prevent moisture-related problems and acid formation that can damage the refrigerant and the system. The other devices don’t create a vacuum: a pressure regulator only maintains a set pressure, a condenser rejects heat and condenses vapor but doesn’t remove air from the system, and a filter dryer traps moisture and contaminants but does not evacuate the system itself.
