Ideal Ceiling Fan Cfm

You could have a fan that moves a lot of air with a high cfm but does so at a high wattage.

Ideal ceiling fan cfm.

For example a bathroom with a volume of 1000 cubic feet 28 3 cubic meters needs a fan capable. Additionally this ceiling fan s motor is reversible making it ideal for all seasons since it can be reversed to warm the room during winter and the other way to cool the room during the summer. Unless you like replacing your ceiling fan every few months or feeling as if you re in a tornado choose a ceiling fan that is proportionate to the room size. Determine the required cfm for your bathroom fan.

An effective bathroom fan should be capable of replacing the entire volume of air 8 times per hour or every 7 5 minutes. For fans that are less than 49 the note will read compare. To arrive at your required cfm simply divide your bathroom s volume by 7 5. This ceiling fan blades arte 44 and it provides an airflow of up to 4 545 cfm ideal for a small room.

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. The cfm represents the airflow required to completely exchange the air in your bathroom 8 times in one hour. What is cfm and ceiling fan airflow. So if you have a bathroom that is 12 feet long 15 feet wide and 10 feet tall then it has a volume of 1800 cubic feet 12 x 15 x 10 and a cfm of 240.

Airflow quantifies the amount of air a ceiling fan delivers and is measured in cfm which stands for cubic feet per minute. A cfm of 75 is the minimum number to make a fan efficient. The result is the cfm or cubic feet per minute rating required for your bathroom fan. A large ceiling fan in a small room will create an uncomfortable amount of airflow.

Airflow efficiency is the cfm divided by the watts amount of energy used to run the fan at its highest speed. This fan brings contemporary style and when hanging at 20 feet it can cover 3 500 square feet. Cfm measurements are taken when a fan is on high speed then that number is divided by the watts used. Cfm is key when determining a fan s airflow efficiency.
