Brian, this topic is well covered on this site. Start by looking at the sizing pages for information about how pressure, and flow work together, for more detailed info.

Essentially, your air compressor has a certain capacity for generating compressed air. For purposes of comparison, typically air compressor companies use the amount of flow at 90 PSI as a yardstick.

Use the flow of 5.2 CFM at 90 PSI to help determine how one air compressor compares to another in terms of air production capacity, and also to see how that air compressor stacks up when considering acquiring it to run a specific air tool you may have. In other words, will the compressor generate enough air to run the air tools you want to use.
