Fan CFM Calculator (Dev)
This fan calculator is typically used to calculate the CFM or cubic feet per minute of air exchange that may be desired in a building. Whether exhausting air or bringing fresh air into a structure, the calculation produced should help to figure out the size of fan(s) required to accomplish the air exchanges needed.
PLEASE NOTE: If you are not sure what kind of CFM's may be needed for your type of facility, please refer to the Commercial & Industrial Applications chart below.
