Ceiling Fan Air Flow Comparison

The amount of airflow a ceiling fan can produce per minute is most commonly measured in cubic feet per minute or cfm.

Ceiling fan air flow comparison.

No need to tolerate squeaky shaky dimly lit or downright gaudy fans any longer. This 31 fan with its powerful motor spins the 6 all weather blades at a 25 pitch to provide 3055 cfm air flow. The more space between the ceiling and the blades the better for air flow and circulation. Ideally aim for at least 12 inches.

If you look into any ceiling fans for patios comparison chart on the web you will see that it is hard to beat the callito in design and functionality. These 6 ceiling fans are quiet powerful and stylish options for your home. Ceiling fan airflow and efficiency are often overlooked but the amount of air your fan moves each minute impacts the level of performance. On average a ceiling fan has an airflow generation of about 5 500 cfm and consumes 70 w.

Blade pitch blade shape and size rpm height from ceiling and motor size. 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. It has an elegant look and features everything you need in a ceiling fan. Dividing the airflow generation by the power consumption gives the ceiling fan s efficiency.

Cfm is the most common form of measurement when speaking about ventilation heating and cooling. The fan s motor the blade pitch and the length and or shape of the fan blades. For rooms with ceilings eight feet or shorter flush mount fans like the cirrus flush mount ceiling fan from modern fan company are the ideal option. Five factors work together to determine the airflow and efficiency of a ceiling fan.

The number depends on a few things. The most energy efficient ceiling fans use less than 60 watts on average and have high airflow. Airflow rating or flow rate is the most effective way to measure the efficiency of a ceiling fan. For fans that are less than 49 the note will read compare.

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.
