What is Free Air Deliver?

Free Air Delivery (FAD) refers to the volume of air that a compressor can deliver at standard atmospheric conditions, typically measured in cubic feet per minute (CFM) or liters per minute (LPM). It represents the actual output of the compressor without accounting for any pressure loss or restrictions in the system. FAD is a crucial metric for understanding a compressor's efficiency and suitability for specific applications, as it helps determine how effectively it can meet the air demands of tools or processes.
