Cfm stands for cubic feet per minute it is also referred to as airflow.
Cfm of ceiling fan.
We tried to keep the list to 60 inches and below.
Ceiling fan efficiency can be represented simply as efficiency cfm watt.
Cfm is short for cubic feet per minute.
Among many other factors rpm blade size pitch motor type etc that decide how good or bad a ceiling fan is cfm is the most important one.
The other ratings are needed in order to calculate the airflow efficiency of a particular ceiling fan.
Below are a number of high cfm ceiling fans for the home.
Put simply cfm is how much air a fan moves.
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.
36 to 48 ceiling fans have airflow efficiencies ranging from approximately 71 to 86 cubic feet per minute per watt at high speed this bit of information is telling you what the expected range of efficiency should be for the size of fan you are considering.
Both the volume of air and the rate the air is moving is measured.
Most ceiling fans we found around 50 60 inches on average have around 4 6k cfm so there are a number of fans not in this list with 6000 cfm or similar.
By diving the product airflow or cfm by the electricity use watts we get a clear understanding of have efficient the ceiling fan is.
It shows you the amount of air that your ceiling fan can move in a minute when running at maximum speed.
For fans that are less than 49 the note will read compare.
