I have been working in compressors and with pneumatic tools for 15 years now and it has always been the same.
The piston displacement makes the compressor look bigger than it actually is. ( but no compressor is ever 100% efficient !!!! )
If you dig a little deeper on the manufacturers specs you will find the FAD output of the unit.
EDIT - the reality is that you will only see a maximum of around 9cfm FAD from a single phase 240v compressor.
If you want more air you have a couple of choises :
1. A three phase compressor
2. Piggyback receivers together to get a bigger storage volume - then pump them up to a higher pressure and use a regulator to supply the air to the spray gun. This way you can extend the storage volume by using pressure differential.
