Ceiling Fan Airflow Rating

Airflow efficiency is the cfm divided by the watts amount of energy used to run the fan at its highest speed.
Ceiling fan airflow rating. Good cfm ranges from 4 000 to 5 000. The four areas that determine airflow are blade shape blade pitch distance from ceiling and motor quality. Airflow is one of the biggest factors to consider when choosing a ceiling fan. The cfm rating of the fan is the key consideration when choosing a fan as it determines the area a fan will cool and circulate.
Shop most reviewed ceiling fans. A cfm of 75 is the minimum number to make a fan efficient. Cfm is key when determining a fan s airflow efficiency. Better ranges from 5 000 to 6 000.
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. This makes it easy to compare two or more fans of similar size. Cfm is the most common form of measurement when speaking about ventilation heating. Cfm measuring airflow efficiency.
What is a dc motor ceiling fan and what are its benefits. At a glance this information helps you to gauge a ceiling fan s airflow and efficiency. But what cfm is best. The amount of airflow a ceiling fan can produce per minute is most commonly measured in cubic feet per minute or cfm.
This is the main point of this article which i explain in more detail further on. Airflow rating or flow rate is the most effective way to measure the efficiency of a ceiling fan.
