CFM of an Airmaster Tiger Compressor

[the snooper]

I received a reply and this is all I got

I can confirm the Tiger 8/25 has a 1.5 hp motor giving a 7CFM displacement with a 24 ltr air receiver.
The max working pressure is 115psi.

no explanation of the numbering system that I asked for

haha, they dont understand it themselves!!
if the product description states "Work Pressure: 60-125PSI 6-25CFM" would that mean my compressor will be struggling to blast oxide grit?
if my compressor is, as the company says, a 7cfm machine?
