https://a.co/d/0gi1uRfT https://a.co/d/09R5irzk Find a good deal on a compressor with 5cfm to 7cfm look for a oil lubed. Size doesn’t matter because you are linking the 2 too work in tandem. I put The link for a 3 way valve above. You run both compressors thru the 3 way valve to the one line out… this line goes to your water separator setup… the line from your water separator goes to your gun. All compressors have a control valve adjustment screw under the cap.(where the swing are is)some have them on top. You adjust the adjustment screw on one compressor so they match. You want both compressors to kick on at ruffly the same time to keep the pressure constant. If you’re lucky there may not need to be any adjustment necessary. You won’t know what adjustments are necessary to your setup is built and your running your gun to see if air pressure drops… Also look for a diaphragm air regulator for your gun and use all hi-flow connections on every thing….
