WebApr 29, 2016 · Auxiliary fans are given a measurement of how much air they can pump, in the form of cubic feet per minute (CFM). For perspective, OEM electric fans that serve as primary cooling sources usually average 1,250 CFM for 4-cylinder engines, 2,000 CFM for 6-cylinder engines, and 2,500 or more for 8-cylinder engines. WebMay 18, 2024 · CFM measures the volume of air a fan moves in cubic feet. The bigger the fan, the more CFM. Our lab technicians measure a fan’s CFM when it's running on high and low speed, then calculate the average. The testing measures are based on the Department of Energy’s (DOE) idea of average daily fan use.
