Definition
CFM refers to the method of measuring the volume of air moving through a ventilation system or other space, also known as “Cubic Feet per Minute.”This is a standard unit of measurement found in many forms of ventilation, both in vehicle and in home heating, ventilation and air conditioning systems.https://www.reference.com/vehicles/cfm-airflow-20969775e326400d
Cubic feet per minute (CFM) is a measure used in Industrial hygiene and ventilation engineering. It describes the rate of flow of a gas or air volume into or out of a space.A standard 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. The volumetric flow rate of a liquid or gas in cubic feet per minute. 1 CFM equals approximately 0.47 liter per second. https://www.convertunits.com/info/cfm
