#AIRFLOW OF CEILING FANS FULL#

We measured and designed our SureSpeed® ceiling fans based on airflow instead of CFM because airflow more directly translates to what you feel from a fan. Ceiling fans work by using the “wind chill effect” to cool people – and the faster the air comes from the fan, the cooler you’ll feel. It’s a lot like when you have the window open in a moving car. Hunter ceiling fans still produce high CFM ratings. We optimize our fans’ motors and blade pitch to move a lot of air while consuming less energy. What is a good airflow for a ceiling fan? So, if fan size and CFM doesn’t always translate to a cooler you – than what does? Let us break it down for you. So, if they turned off the central air, you wouldn’t feel the coolness you desire. Yet, the air you feel isn’t coming from that fan, it’s from a central air system. Think about when you’re at a gym, Costco, or Walmart – those big fans have a higher CFM than your fan at home. Simply put: CFM measures how much air is being moved while air velocity measures how fast it moves. The bigger the fan and greater CFM, doesn’t always translate to a cooler you. Airflow relates to the speed of the air movement, measured using miles per hour (mph).The testing measures are based on the Department of Energy’s (DOE) idea of average daily fan use. The bigger the fan, the more CFM. Our lab technicians measure a fan’s CFM when it's running on high and low speed, then calculate the average. CFM measures the volume of air a fan moves in cubic feet.The first thing to understand when evaluating which ceiling fan moves the most air and will cool you best is the difference between CFM and velocity. While CFM does talk about the air in relation to the fan, there are many more factors that go into a fan to produce the best airflow. If you would to confirm certain details of the product or would like some more information please either contact the suppliers service line (especially for technical support or questions) or us on our contact page.There’s nothing like the feeling of a cool breeze from a fan during a summer day. To achieve it, you need a ceiling fan that moves the most air. When choosing the right fan, some look at the CFM (cubic feet per minute) number on the box or online product page. This may include certain specifications upgrades or changes, design alternation and colour changes or variations. While we do our best to keep it as accurate and up to date as possible some changes may occur without notice. Product information is provided by the manufacturer/supplier/distributor of this product.
