 Actual cubic feet per minute

Actual Cubic Feet per Minute (ACFM) is a measure of the volumetric flow rate of gas or air at actual (real) conditions of temperature and pressure. It is used to describe the flow rate of a fluid in terms of cubic feet per minute, accounting for the actual conditions under which the fluid is flowing. ACFM is particularly important in applications where gas behavior can vary significantly based on temperature, pressure, and composition.
