I am not sure exactly what your question is but I know what SCBA you have and here are some specifics. The first stage regulator is in the backframe (hidden) and it operates (depending on whether you have high or low pressure) is between 2216 and 4500 psi, you have high pressure. After it leaves the first stage regulator it drops from the 4500 to @118 psi in the line that goes over to your face piece. In the mask it is supposed to always have a static psi of 3 to 4 psi (I think), that accounts for heavy breathing it is supposed to ALWAYS have a positive pressure in the mask.

Hope this helps
