Sorry, you already rated this answer. This is a standard unit of measurement found in many forms of ventilation, both in vehicle and in … The number depends on a few things: the fan’s motor, the blade pitch and the length and/or shape of the fan blades. A 125cfm fan can remove all of the air from a box that is 5ft x 5ft x 5ft in one minute (assuming vents allow fresh air to fill the vacant space). The measurement is taken when the ceiling fan is on its highest speed and uses both the volume of air and the rate at which it moves. CFM stands for “cubic feet per minute” and is a measure of air flow, often used to describe the capabilities of heating, ventilation and air conditioning systems. CFM refers to the method of measuring the volume of air moving through a ventilation system or other space, also known as "Cubic Feet per Minute." that decide how good or bad a ceiling fan is, CFM is the most important one. It describes a volumetric flow of a substance. CFM is the acronym for Cubic Feet per Minute — the measure of air volume moved by the fan blower. It is commonly used by manufacturers of blowers and compressors. Put simply, CFM is how much air a fan moves. Since the volumetric capacity refers to the volume of air or other gas at the inlet to the unit, it is often referred to as "inlet cubic feet per minute" (ICFM). Among many other factors (RPM, Blade Size & Pitch, Motor Type etc.) Actual cubic feet per minute (ACFM) is a unit of volumetric flow. cfm is cubic feet per minute. Choose a fan with a CFM rating appropriate for your room size to ensure adequate ventilation. It describes the rate at which a certain volume of air moves in a certain period of time. It shows you the amount of air that your ceiling fan can move in a minute when running at maximum speed. This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation. CFM is short for cubic feet per minute. Don't skimp, since this should be a one-time purchase for most homeowners. Calculate the total volume of your bathroom. 384 cubic feet ÷ 5 = 76.8 CFM or Cubic Feet per Minute Based on personal experience, I would recommend purchasing the best quality fan you can afford that exceeds your computed CFM value. This is done by multiplying your bathroom's floor area … Was this helpful?10Thank you for your vote! In the case of a blower or fan, it indicates how much air it can move per minute.
