"Cubic feet per minute (CFM) is an often confusing term because it has no single definition that applies to all instances. Gases are compressible, which means that a figure in cubic feet per minute cannot necessarily be compared with another figure when it comes the mass of the gas. To further confuse the issue, a centrifugal fan is a constant CFM device or a constant volume device. This means that, provided the fan speed remains constant, a centrifugal fan will pump a … " - Standard volume flow
