![]() ![]() ![]() As we mentioned CFM is to measure how much volume of air fan can move. Not only the fan size itself but also the room size. To kick it in, let's begin with the most basic thing you will need to consider before you purchase the ceiling fan, the Size. So let's see what factors will have an indirect effect on the ceiling fan airflow. Other Factors that Affect Ceiling Fan AirflowĪlthough the major factors that impact on the ceiling fan's airflow are CFM and velocity, some factors will change the performance of the CFM and the velocity, since our living space is not like the testing lab. For example, if a fan with a high CFM but a low velocity(Like the ones at the gym, large but span slowly), you may not be able to feel it, or at least you won't feel the wind across your skin. These two factors will affect the ceiling fan's airflow at the same time. In a short conclusion, CFM shows how much the air moved and Air Velocity shows how fast the air moved in a specific room space, which combined to describe the airflow for the ceiling fan. Or more specifically, the higher the air velocity, the less time it will take for you to feel the temperature changing. Air velocity refers to the speed at which your ceiling fan moves the air throughout the space. ![]() About Air VelocityĪir Velocity is also an important value to measure a ceiling fan's airflow. You can easily find it in the specification tabs. At Smafan, we provide all of our ceiling fan's CFM data from our own testing lab. But don't worry, you don't need to perform these calculations manually. To calculate CFM, it is very simple CFM = Area (in square feet) X Velocity (in feet per minute). Normally, the bigger size of the fan will have more power to move more volume of air while running. Typically, the higher of CFM amount, stands for the more air the fan moves, resulting in a more noticeable breeze. It is determined by the cubic feet of air volume moved by the fan per minute. So what does CFM mean? CFM is the common measure to quantify the volume of the air movement. So what is the difference between them? What Is CFM One is the CFM, which stands for Cubic Feet Per Minute, and the other is the Air Velocity. To understand how your ceiling fan functions well, there are two concepts that you definitely need to know. For personal, we will have a much stronger feeling about wind while under a ceiling fan has a better airflow. A "good airflow" means that the ceiling fan can move an adequate volume of air to create the desired cooling or air circulation effect in the room. The ceiling fan has more ability to effectively circulate air and provide comfort in a given space. A ceiling fan has good airflow means it has a high CFM and Velocity. We'll break down the meaning of CFM and air velocity and provide additional factors that can contribute to your cooling breeze or can be the cause of your ceiling fan not making you feel cool! What Is a Good Airflow For a Ceiling Fanįirst of all, we need to build up a concept of what is a good airflow for your ceiling fan. In today's blog, we are unveiling the secret of the ceiling fan airflow. Ceiling fan has been a staple in living space for decades, yet, there is much more you need to know to meet your comfort. ![]()
