My setup is as follows:
From the comp, I ran 1/2" copper tubing 6 ft. The copper is coiled and runs to a pvc coupler. This reduced the vibration and allows a cool-down point before it goes to the pvc.
From there, I ran 15ft of 3/4" pvc to a "dryer". My dryer is 100ft of 3/4" pvc zig-zagged along the back wall of my shop. The theroy is if you run the air far enough that it cools, the water vapor will return to a solid form and fall out of the air supply. Works excellent for me and I`m in muggy TN, lol.
At the bottom of the "dryer" I have a drip leg to drain off the water.
From there I run to this particulate filter

From that filter I run directly into this filter

After those filters, I run out to all my drops throughout my shop. I have very clean, dry air at every drop in my shop. I do still run the mini desicant filters

Hope that helps.
