Ceiling Fan Airflow Chart

To help you pick one for your house we have compiled a list of the best airflow ceiling fans on the market rated according to their size power material and color.

Ceiling fan airflow chart.

Blade pitch blade shape and size rpm height from ceiling and motor size. Cfm is key when determining a fan s airflow efficiency. Those designed for airflow and those designed for static pressure. Cfm measurements are taken when a fan is on high speed then that number is divided by the watts used.

Case fans generally come with two types of fins. Some fans and cases even come with manual switches for basic fan control. Cfm measuring airflow efficiency. For fans that are less than 49 the note will read compare.

Cfm is the most common form of measurement when speaking about ventilation heating and cooling. Ceiling fan manufacturers are required by the doe to publish the airflow of each fan in cfm cubic feet per minute which is not the same as wind speed. Airflow optimized fans are quieter and great for unrestricted areas like the front of your case. Airflow rating or flow rate is the most effective way to measure the efficiency of a ceiling fan.

Cfm is the volume of air being moved every minute whereas wind speed how fast the air is moving in mph miles per hour or lfm linear feet per minute both of which are directly related to. Airflow quantifies the amount of air a ceiling fan delivers and is measured in cfm which stands for cubic feet per minute. 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. Airflow or static pressure.

Five factors work together to determine the airflow and efficiency of a ceiling fan. The size of a ceiling fan is determined by the size of the room or the area which you are looking to. The four areas that determine airflow are blade shape blade pitch distance from ceiling and motor quality. Airflow efficiency is the cfm divided by the watts amount of energy used to run the fan at its highest speed.

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. A ceiling fan can greatly improve the oxygen flow in your home and make it fresher. Ceiling fan airflow and efficiency are often overlooked but the amount of air your fan moves each minute impacts the level of performance. A large ceiling fan in a small room will create an uncomfortable amount of airflow.
