Two different compressors can have the same pressure at different flow rates. It simply means that the compressor with the larger flow rate can pump more air per unit time assuming the pipe cross-section areas (diameters) are the same for both.
Another example: We can push a small amount of air from a nozzle at high er pressure without changing the flow rate. To have larger flow rate of air at the same pressure, we need a larger cross-section pipe and a larger compressor.

Fair enough, I already gave the short version earlier, doesn't matter if people won't listen though.
Either way, good concise explanation!
