True or False: Vacuum pumps have a volumetric capacity that can be rated in CFM?

Vacuum pumps indeed have a volumetric capacity that can be rated in cubic feet per minute (CFM). This measurement indicates the volume of gas that a vacuum pump can remove from a given volume of space per minute, which is essential in various applications, including refrigeration and air conditioning systems. Understanding the CFM rating of a vacuum pump is crucial for technicians because it helps ensure that the pump can effectively create the necessary vacuum level for different systems. Therefore, having a CFM rating is a standard approach to evaluating a vacuum pump's performance across various contexts, not just limited to industrial use or specific types of pumps.
