You can just see the oiler to the right of the regulator. I am trying this mounted here because I've not really been happy with it hanging out the bottom of the tool I am using.
I am using Nitto quick disconnect fittings to connect everything together. Unfortunately they do introduce some restriction to flow. But with the amount of air I am using is not really that much. Once I get this space cleaned up a bit and I'm happy with it I will probably plumb it together with plain tapered fittings so as to minimize restrictions.
I've got some more work I've been doing on the CNC that I need to finish before I can put up here.
