Cubic Feet Per Minute (CFM) is a measurement used to quantify the flow rate of air or other gases. It indicates how many cubic feet of air pass through a specific point in one minute. CFM is commonly used in various applications, including heating, ventilation, and air conditioning systems, to ensure adequate airflow for comfort and efficiency. Understanding CFM is essential for selecting the right equipment, such as fans, blowers, or air purifiers. Higher CFM ratings typically mean more air movement, which can improve indoor air quality and temperature control. Proper CFM calculations help optimize performance in both residential and commercial settings.
