ACRONYM - Actual cubic feet per minute.( 099)

Means 'actual cubic feet per minute'. In air and gas streams ACFM is the actual flow. When corrected for pressure and temperature, it can be correlated to SCFM (standard cubic feet per minute).

Actual Cubic Feet per Minute of gas volume at the actual conditions of temperature, pressure, moisture, elevation and gas composition. See gas flow rate.

The acronym for actual cubic feet per minute, which is the actual gas flow rate expressed in the American Engineering system of units. ACFM is a measure of the volume of gas that passes a given point during a one-minute period.

When manufacturers list performance for blowers and compressors it is stated as "Capacity" in CFM (Cubic Feet per Minute). This refers to the volume of air at the inlet to the unit, therefore this is often referred to as Inlet CFM (ICFM) or Actual CFM (ACFM). These terms are used interchangeably and mean basically the same thing (CFM, ICFM, ACFM).
