Hi Joe,
I would say that if the two outlets are in-line and connected to a single pipe coming from the regulator, then the second outlet will receive air pressure at exactly the same rate as the first outlet. In this scenario:
- One single pipe exits the air tank outlet, going straight into the regulator INTAKE inlet.
- One single pipe out of the regulator valve exit outlet then splits to two outlets. I would guess this is probably the case.
Thus, in the predictable scenario above, if you wish to have the second outlet with an independent air pressure which may have to be different from the pressure going to the airbrush connected to the first outlet, you will be looking at a substantially different pipework. In my view, it would require a "
T" splitter pipe coming out of the single outlet in the air receiver tank, meaning air would exit the tank at full pressure, then travel at that pressure through the two exits in the "
T" splitter, each of these splitter exits would have to be connected to solid pipes of a suitable diameter and calibre (pipe wall thickness) so they can sustain full pressure until each pipe then reaches two separate regulator valves/filters. Then yes, you would be able to regulate REG. 1 to one pressure and REG. 2 to another pressure.
My strongest recommendation is to contact Sparmax Technical Support and ask for advice and how to go about doing that alteration. Compressors are sensitive beasts, best not to fiddle with them unless you are a professional technician who knows air compressor business inside out.
Do not modify the air compressor yourself. Any warranty will be null and void instantly and if anything goes South, Sparmax will not accept liability... Not to mention a potentially serious risk to yourself.
