Using a Tuxing Water Separator on the Input Instead of Output

[Squirrelmageddon]

@Squirrelmageddon let's assume for the sake of this discussion that zeolite desiccant actually works at the input side. The reason dive compressors use zeolite after the water separator instead of before it is so the water separator can remove 99% of the moisture. The zeolite is there to catch that last bit of moisture that the water separator misses. Zeolite is almost impossible to recharge in a home oven because it requires several hours of baking at higher termparatures than home ovens can reach. Silica gel beads can be easily recharged in a home oven at 200 degrees F for 15 minutes laid out in a flat pan.
So even if what everyone is telling you is wrong and your input filter actually is working, it is not a good idea to waste zeolite removing the bulk of the moisture in the air before the water separator can do its job.

I completely understand and concur that a water separator between the compressor and gun/tank is critical. My purpose of this post is to show the results of an idea I had to help prolong the life of the output filter media so that we don't have to use large output filters which double our fills times. This is important to everybody using small compressors that overheat in fills over 8 minutes. My new 300 bar 580cc tanks were taking so long I had to shutdown, cooldown, and finish off the tanks. It was a 15 minute process per fill. So I switched to a smaller filter which allows me to fill the tanks much faster. That created another problem. Those small 4" filters are too small to fill all day at the range. I had to carry desiccant with me because they completely saturated 1/2 way through the day. This project solved that issue. I can now use a small output filter all day. Problem solved.

Also, the reason I left the zeolite in instead of using the 20 lbs of silica beads I have was because I was going to throw it in the garbage eventually and didn't want to be wasteful. I wanted to get some runs on it and compare results with silica beads just for poops and grins. So I got my numbers, threw it in the garbage, and replace it with silica beads. Here's the results:

Silica beads dropping humidity level from 72% to 10%

I am going to hookup the small 4" filter and fill with that. I believe, judging from what I see, I can probably fill all day with that and just keep my 7" for when I go somewhere for the weekend and don't want to carry desiccant.
