Cubic Feet per Minute (CFM)

pc

CFM is a unit of measurement for volumetric airflow.

expanded

Cubic Feet per Minute (CFM) quantifies the amount of air a system can move in a minute, which is critical for evaluating airflow capacity in ventilation systems. It is commonly used in industries to specify the efficiency of fans, blowers, and HVAC systems in maintaining air quality, temperature, and safety standards.

examples

A residential bathroom exhaust fan that ventilates 150 cubic feet (approx. 4.25 cubic meters) of air per minute.

Used in residential bathrooms to manage humidity and odor, maintaining air quality and preventing mold.

An industrial air compressor having a CFM rating of 75 cubic feet per minute at 100 psi.

Commonly used in manufacturing settings for powering pneumatic tools and equipment.
