Ceiling Fan Airflow Rating
What is a dc motor ceiling fan and what are its benefits.
Ceiling fan airflow rating. Airflow rating or flow rate is the most effective way to measure the efficiency of a ceiling fan. At a glance this information helps you to gauge a ceiling fan s airflow and efficiency. Shop most reviewed ceiling fans. Best is over 6 000.
See what gives a fan power airflow efficiency and why. This is the main point of this article which i explain in more detail further on. Cfm is the most common form of measurement when speaking about ventilation heating. The amount of airflow a ceiling fan can produce per minute is most commonly measured in cubic feet per minute or cfm.
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. 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. Cfm measuring airflow efficiency.
The best fans have an airflow of 3 000 cfm or above. Airflow efficiency is the cfm divided by the watts amount of energy used to run the fan at its highest speed. A cfm of 75 is the minimum number to make a fan efficient. Airflow is one of the biggest factors to consider when choosing a ceiling fan.
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. Better ranges from 5 000 to 6 000.
