What Size Vacuum Pump is Best for Auto AC Systems?
The size of the vacuum pump for auto AC will depend on the system’s capacity and the type of work being performed. A small pump with a 1-2 CFM (cubic feet per minute) rating is suitable for basic maintenance tasks, while larger systems may require a 6-8 CFM pump for proper evacuation. It is important to choose a vacuum pump that is appropriate for the specific automotive AC system being worked on to ensure its effectiveness.
