I have a 20A oil-filled (20 lt p/min) max. 85 psi with a 1.5 litre air tank. I was told the working pressure is 30 psi and would like to know what that means. Can someone explain it to me please?

A few weeks ago I took the motor off my old compressor and used the 3 litre air tank to add to my new compressor so I have a total of 4.5 litre air storage. At the moment I have my 20A compressor with 1.5 litre air tank set at 30 psi, which goes to the 2nd 3 litre air tank, which is set at 20/30 psi for my airbrush. I have read other people with this kind of set up have put the compressor psi, going to the 2nd air tank, set high (60 psi or more).

Should I do this? Say, 50 psi from compressor and 20/30 psi on 2nd air tank?

What if I want to do T shirts at airbrush 40 psi, should I put the compressor psi to 60?

Obviously I can't airbrush at 40 psi if my compressor psi is 30 psi (working pressure?!), can I?

Any insight really appreciated
