In this video, I give a basic overview of how I added an after cooler between the compressor head and tank of my 60 gallon Sanborn upright air compressor. Depending on your compressor make and model, fittings may be slightly different than the types and sizes I’m linking to below, so please VERIFY before purchasing and attempting to install anything. There’s more than one way to pipe something like this in, so use what works for you. The links below are just to help streamline the process if you want to do it like I did. The concept should work the same regardless of your compressor. This mod will NOT remove 100% of moisture from your compressor, but it makes a very large difference. If you still have moisture issues after doing a similar modification, you may have to add other methods of water reduction to your aftercooler, such as desiccant filters or water traps. I water seperator between your air line and tank is still a good idea regardless.

Disclaimer: Modify at your own risk. This video is for informational/entertainment purposes only. It’s not an exhaustive “how to” on modifying your compressor. I am not an expert. If you choose to do a similar mod to yours, realize that you’re working with high pressures, high temperatures, and moving parts. Turn the compressor OFF before doing anything. Do NOT remove your tank’s check valve, and make sure you know which parts you are adding or removing, and what they do. It might be a good idea to drain your tank, though I didn’t have to when I did mine. I encourage you to watch more than this video, and see how others have done this mod as well. Be safe, and thanks for watching!
