What is what does cfm stand for?

CFM stands for cubic feet per minute, which is a measure of the volume of air that is moved by a fan or blower in one minute. It is a common measurement used in air conditioning, heating, and ventilation systems, as well as in industrial and commercial applications such as dust collection systems, air compressors, and pneumatic tools. The higher the CFM rating, the more air the fan or blower can move, which is important for maintaining proper air circulation and ventilation in a given space. CFM is also used as a measurement of airflow in performance testing for fans, HVAC systems, and other equipment.
