When it comes to understanding air flow, CFM and SCFM are two terms that are often heard. But what do they mean, and how do they differ? In this blog post, we’ll break down the difference between CFM and SCFM, so you can understand which one is right for your needs.
What is CFM?
CFM stands for cubic feet per minute, and it is a measure of the volume of air flowing out of a fan or other device. CFMs are typically used to measure the airflow of HVAC systems, but they can also be used to measure the output of other devices such as exhaust fans and blowers. CFM is usually calculated by dividing the total volume of air moved by the device in a minute by the number of cubic feet in that minute.
For example, if a fan moves 100 cubic feet of air in one minute, its CFM would be 100 CFM. CFMs are often used to compare the performance of different fans or devices. Higher CFM ratings usually indicate more powerful devices.
What is SCFM?
SCFM is an acronym that stands for Standard Cubic Feet per Minute. It is a unit of measure used to indicate the rate of airflow. SCFM is typically used to measure the flow of gases, such as air, through a pipe or duct. It can also be used to measure the capacity of a particular type of containers, such as a tank or compressor. SCFM is a useful metric for determining the efficiency of various systems and equipment. It can also be helpful for troubleshooting various issues that may arise in those systems.
Difference between CFM and SCFM
CFM, or cubic feet per minute, is a measure of the volume of air that a fan can move in a minute. SCFM, or standard cubic feet per minute, is a measure of the volume of air that a fan can move in a minute when it’s operating at standard conditions. The main difference between CFM and SCFM is that CFM takes into account the density of the air, while SCFM does not. CFM is therefore a more accurate measure of a fan’s true performance.
CFM and SCFM are two important metrics to understand when it comes to airflow. In order to make the right decisions for your business, it’s important to know the difference between the two. We hope this article has helped clear up any confusion and that you feel confident in using CFM and SCFM when making future decisions about your HVAC system.
