Measure of volume of air. When testing systems, find the CFM by multiplying the face velocity (amount of air passing through the face of an outlet or return) times the free area (the total area of the openings in the outlet or inlet through which air can pass) in square feet.
Stands for Cubic Feet per Minute. This measurement indicates how many cubic feet of air pass by a stationary point in one minute. The higher the number, the more air is being moved through the ductwork by the system.
Cubic Feet Per Minute A measure of the volume of a substance flowing through air within a fixed period of time. With regard to indoor air, refers to the amount of air, in cubic feet, that is exchanged with outdoor air in a minute's time; i.e., the air exchange rate.
Stands for Cubic Feet per Minute. A measurement of airflow that indicates how many cubic feet of air pass by a stationary point in one minute. The higher the number, the more air is being forced through the system.
Cubic feet per minute. CFM is the volume of air, in cubic feet, that the compressor can pump in one minute at a specific working pressure. The CFM air delivery at a given working pressure, not the displacement or the horsepower, is the true rating of a compressor. The CFM rating of the compressor is more important than the motor HP and should be considered carefully when selecting an air compressor. Single stage compressors are rated at both 40 PSI and 90 PSI, while two-stage compressors are rated at 100 PSI and 175 PSI. Compressors with high CFM ratings provide more air, thus making higher CFM units more practical for larger applications.
Acronym for cubic feet per minute. A term used to describe the amount of air that an air blower will move. It is sometimes used to describe the amount of water moving past a point in a circulation system.
(Cubic Feet per Minute) - Measurement of air volume either used by a tool or produced by the compressor. For compressors it represents the output if the compressor were perfect (i.e. no friction, etc.) Also see SCFM.

Configuration management. (1) One of the five functional application areas for network management defined by the ISO, concerned with installing, initializing, loading, modifying, and tracking the configuration parameters of network hardware and software. (2) The addition, modification, or deletion of information that defines the behavior of an application, computer, or network device.
