Airflow rating or flow rate is the most effective way to measure the efficiency of a ceiling fan.
Ceiling fan airflow rating.
What is a dc motor ceiling fan and what are its benefits.
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.
Better ranges from 5 000 to 6 000.
Good cfm ranges from 4 000 to 5 000.
This is the main point of this article which i explain in more detail further on.
Airflow efficiency is the cfm divided by the watts amount of energy used to run the fan at its highest speed.
See what gives a fan power airflow efficiency and why.
The best fans have an airflow of 3 000 cfm or above.
Airflow is one of the biggest factors to consider when choosing a ceiling fan.
Best is over 6 000.
At a glance this information helps you to gauge a ceiling fan s airflow and efficiency.
The amount of airflow a ceiling fan can produce per minute is most commonly measured in cubic feet per minute or cfm.
Cfm measuring airflow efficiency.
A cfm of 75 is the minimum number to make a fan efficient.
Shop most reviewed ceiling fans.
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.
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.
