Centrifugal fans do double duty, handling Mass Flow and Volumetric Flow at the same time. They’re simple measurements that are important to sizing and specifying fans for your application.
AirPro Sales Manager / Senior Application Engineer Chet White shows you the two most common types of flow in your centrifugal fan in this brief whiteboard video.

Centrifugal fans are moving what we typically refer to as two things. One is Mass Flow. The other is Volumetric Flow. And every centrifugal fan application is doing both at the same time. So we’re going to look at real quick what these two things represent.
When we’re focused on Mass Flow, usually the application is something that requires a certain product to get moved from point A to point B that has mass. And so what we focus on in this is the mass of whatever it is that we’re trying to move over time, and that gives us Mass Flow. In this case, the typical units used in the United States, we’re using pounds per second, pounds per minute, pounds per hour, kilograms per second if you’re on metric, kilograms per minute - you’re looking at mass over time.
Fans are also doing Volumetric Flow, and you probably care more about this if your application is more like trying to ventilate a room. And so you’re trying to keep an air exchange rate within a room, you’re focused more on Volumetric Flow because a room is a volumetric space. And so the units we’re looking at for this are volume over time. And most centrifugal fan manufacturers use Volumetric Flow when they’re sizing a fan. And the most common unit in the United States is CFM. What that stands for is cubic feet per minute. Again, that could be cubic feet per second, per hour, it could be cubic meters per second - whatever your units are.
Cubic feet per minute, in this case, refers to Volumetric Flow, and pounds per second refers to Mass Flow. And that’s the difference between the two types of most common flow.
