DIY Low Cost Compressed Air Dryer Water Separator Overview

Uploading this a few months after originally recording since I've confirmed that it's been working great without any issues. I cost me ~$150 to assemble what you see in the video, took a day to put together.

Note that I am using this mostly for water separation from my small oil-free compressor. If you're a painter, high CFM, etc. the system will have to be adjusted accordingly like I mentioned in the video and may begin to seem like a less attractive option vs buying a commercial solution.

Potential upgrade options: desiccant stage after the air filter followed by another air filter (for desiccant particles), air filters with automatic drain, AC fan attached to the radiator that's wired to the compressor's switch (turns on with the motor), thermoelectric chiller stage to further assist with water condensation and separation, in-out moisture sensors (cool but I only found expensive options which are far outside the intention of this setup), DIY regenerative desiccant system (doesn't look that difficult tbh hmu if someone's interested to help me with this idea), etc.
