High Airflow Efficiency Ceiling Fans

Airflow efficiency is the cfm divided by the watts amount of energy used to run the fan at its highest speed.

High airflow efficiency ceiling fans.

Energy star certified most efficient 2020 ceiling fans. High airflow ceiling fans ceiling fans with high airflow move more than 7000 cubic feet of air per minute cfm. Products that make the energy star most efficient list for 2020 deliver cutting edge energy efficiency along with the latest in technological innovation. Ideal for high ceiling rooms.

The most energy efficient ceiling fans use less than 60 watts on average and have high airflow. These fans are designed to keep significant amounts of air flowing in large areas. To qualify for energy star certification a fan must produce at least 155 cfm 100 cfm and 75 cfm of airflow per watt on the high medium and low speeds respectively. See what gives a fan power airflow efficiency and why.

Ceiling fan efficiency can be represented simply as efficiency cfm watt. By diving the product airflow or cfm by the electricity use watts we get a clear understanding of have efficient the ceiling fan is. Blade pitch blade shape and size rpm height from ceiling and motor size. Cfm stands for cubic feet per minute and is a measure of how much air a fan circulates while it runs.

Ceiling fan airflow and efficiency are often overlooked but the amount of air your fan moves each minute impacts the level of performance. They represent the year s very best for energy savings and environmental protection. With above average cfm ratings high airflow ceiling fans are designed to move large amounts of air using their oversized blades and powerful motors. Learn all the information you need to start shopping including product details rebates and.

You could have a fan that moves a lot of air with a high cfm but does so at a high wattage. For fans that are less than 49 the note will read compare. The other ratings are needed in order to calculate the airflow efficiency of a particular ceiling fan. A cfm of 75 is the minimum number to make a fan efficient.

The four areas that determine airflow are blade shape blade pitch distance from ceiling and motor quality. Five factors work together to determine the airflow and efficiency of a ceiling fan. This is different that wind speed which is reported in miles per hour. Cfm is key when determining a fan s airflow efficiency.
