Air flow is the volume of air that is produced by the fan measured by time. In this case, the air flow of a fan is measured in cubic meters per minute (m³/min) in metric units, or cubic feet per minute (CFM) in imperial units. In simplest terms, if you have a 5 ft x 5 ft x 5 ...

WebbI dag · Centrifugal Air Blowers. Centrifugal blowers use high-speed impellers or blades to impart velocity to air or other gases. They can be single or multi-stage units. Like fans, centrifugal blowers offer a number of blade orientations, including backward curved, forward curved, and radial. Blowers can be multi- or variable speed units.
