Large Span Ceiling Fans

What are these Ceiling Fan Comparison Graphs?

As of January 1, 2009, all ceiling fan manufacturers are required to test and publish data regarding the performance of their fans. Specifically, the CFMs (Cubic Feet per Minute of Airflow), the Watts (amount of electricity used per hour) and the Efficiency (EPA defines as CFM/Watts).

We have added this new information to our previous rating system and come up with an even better method of comparing ceiling fans. These new "Comparison Graphs" allow you to easily compare ceiling fans at a glance. Once you understand how to interpret these graphs, it becomes quite easy to compare the perforance of any fan on our site at a glance.

Room Size and CFM Chart

Although the EPA now requires fan manufacturers to publish the CFM ratings of their fans, there is no standardized scientific method of determining what size and CFM fan is best for any given application. A few quick searches and you will find that each ceiling fan manufacturer interprets this differently. So we created our won size and CFM recommendation chart to give you an idea what we recommend for "typical" applications. We produced this chart based on over 20 years of experience dealing with ceiling fans and the people who we've sold them to. For the most part, this chart will suffice. If you have low ceilings, you can fudge a little on the CFM and use a fan in the lesser range of the room size. If you have high ceilings, you need more CFM and a fan closer to the larger size of the chart. In most cases, the more the CFM the better and the higher the quality score the better!
