!. Anyone know where I can purchase replacement yong heng crankcase breathers?

2. Anyone out there using two filters like this below on the air outlet of their yong heng compressors, to be extra safe as far as water and oil separation?

Yes. I paid about $150 for it on Amazon. I figured the YH was cheap air, but the Filter was an investment to keep my guns and bottles safe. I dont regret it.

Currently 60 degrees F and 80% humidity here in Los Osos.

If I charge an 88 cuft SCBA cylinder from 0 psig up to 30 bar (4500 psi), without trapping/venting the condensation, I would end up with about 1 ounce of water (2 tablespoons) in the tank.

I recently got one of these compressors (not a Yong Heng, but looks about the same). I use the filter that came with it, but I also open the high pressure vent/trap periodically while filling a tank. That trap is small so needs to be vented fairly often. If you do that, very little condensation should end up in the tank.

After the tank is filled to full pressure, I turn it upside down for a bit and then bleed off any condensation that made it into the tank.

I feel comfortable doing it this way, but a bigger filter/trap would be more convenient and probably more effective.

Rather than use two small filters, I'd simply change the element more often.

"Tweeter"I know people have been buying this filter from Lethal Air and say it works as well as the gold filter. Only $50 also.

The pump I got came with a small filter (blue anodized aluminum housing). Similar to that one. If the object is to remove significant amounts of water, I don't see much point in the horizontal filters. Better to have a a vertical separator/trap (like MarkNagel showed). Like these:
