Ceiling Fan Airflow Rating

See what gives a fan power airflow efficiency and why.

Ceiling fan airflow rating.

Airflow is one of the biggest factors to consider when choosing a ceiling fan. Airflow efficiency is the cfm divided by the watts amount of energy used to run the fan at its highest speed. Cfm is key when determining a fan s airflow efficiency. The four areas that determine airflow are blade shape blade pitch distance from ceiling and motor quality.

Cfm is the most common form of measurement when speaking about ventilation heating. This is the main point of this article which i explain in more detail further on. A cfm of 75 is the minimum number to make a fan efficient. The best fans have an airflow of 3 000 cfm or above.

What is a dc motor ceiling fan and what are its benefits. Cfm measuring airflow efficiency. But what cfm is best. Although a higher number is desirable fans with a very high airflow rating cfms that have an average efficiency rating may in fact be the better choice.

The amount of airflow a ceiling fan can produce per minute is most commonly measured in cubic feet per minute or cfm. Airflow rating or flow rate is the most effective way to measure the efficiency of a ceiling fan. Shop most reviewed ceiling fans. Better ranges from 5 000 to 6 000.

At a glance this information helps you to gauge a ceiling fan s airflow and efficiency. This makes it easy to compare two or more fans of similar size.
