SCFM is a metric based on standard conditions, so it’s universally used. CFM is the more commonly used measurement in the United States, since most airflow measurements are made in inches of water.The calculation above is available as an excel file -. Air, LNG, LPG and other common gas properties, pipeline capacities, sizing of relief valves. Vacuum is defined as air pressure below atmospheric pressure. Convert vacuum air volume to standard air volume. Vacuum pumps - calculate flow rate and required evacuation time. Actual cubic feet per minute ( ACFM) is a unit of volumetric flow. It is commonly used by manufacturers of blowers and compressors. [1] This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition ...
