Filter arrived today.I'll be using it to replace the small filter that come's with the Yong Heng.It has a tampon on the inlet side,then charcoal with just a small piece of toilet paper covering the charcoal on the outlet side. Should I remove a small amount of charcoal and put in another full size cotton tampon on the outlet side or remove the charcoal and fill the filter with tampon's?
Black filter question?

I recommend that you remove the charcoal and fill with some sort of desiccant. Preferably, Zeolite 13x. Leave the Tampon on the inlet side and put another on the outlet side. The inlet side should be about twice the size of the outlet side. Until you receive the Zeolite I would just use the filter full of the cotton tampon material. The activated charcoal does nothing for the intention of the filter, which is to remove moisture.

I'm using mine in the opposite direction. The charcoal is supposed to remove the oil fumes first to stop the desiccant, clogging with oil instead of absorbing water. The tampon filter is the last trap in the line. When the original packing is spent, I will be replacing the filling with zeolite. Instead of replacing the OE filter, why don't you leave it in place, before the larger one. I think that you will find that it catches 90% of the oil and water first.

Dumped the charcoal.Going with tampon's for now, until I get zeolite.I'm filling directly to the rifle from 170bar to 210bar,so the compressor run's less than a minute.

That will work just fine. Did your black filter come with a hose? Mine burst the first time I pressurised it at about 200 Bar. Supposed to have a working pressure of 630 Bar. I got an $8.00 USD refund which brought the price down to about 20 bucks. Not bad with all the spare filters and Orings.

Smart man. See photo below of what actually stops any oil fumes. That dirty cotton tampon was at the inlet of my gold filter, then Zeolite 13x, then the clean cotton tampon at the outlet. Make sure you get good compression of the cotton tampons when you screw the last cap on. Lesson learned for me is to use the longer filter at the inlet and the shorter filter at the outlet
