WebOct 22, 2024 · In layman’s terms, a fan curve is a graphical representation of exactly what a fan can do. It is a measure of fan performance, which is determined by relationships … WebThe fan volume flow rate (airflow) is commonly expressed in cubic feet per minute, or CFM. Therefore, the system pressure loss and volume flow rate requirements are typically expressed as a certain value of static pressure (SP) at some CFM. The fan “pressure-volume” curve is generated by connecting the fan to a laboratory test chamber.
