I have the black filter but mine was purchased from lethal air before this one showed up on aliexpress. I replaced the carbon and silica gel with 13x alumina silicate molecular sieve with color changing beads. https://www.amazon.com/gp/product/B07CJXDBV2/ref=pe_253590_291545930_em_1p_4_ti
I tried and used both (black & gold) and I prefer the black. Personal opinion is I don't have to waste as much air pressuring the gold filter compared to the black filter. Run time for YH is less.I think the gold is fine for larger compressor. But what do I know I'm just a consumer learning as I go
The gold filter holds 100% more desiccant than a black filter.
Have any of you bought on of these? There much cheaper than the gold filters. https://www.aliexpress.com/item/High-pressure-Pcp-air-filter-Oil-water-Separator-For-High-Pressure-pcp-compressor-4500psi-30Mpa-300bar/32870846268.html?spm=2114.search0126.96.36.199a1735dcRhXsSG&ws_ab_test=searchweb0_0,searchweb201602_3_10065_10068_10130_10547_10546_10059_10548_5016815_10545_5016715_10696_100031_10084_5016615_10083_10103_451_10618_452_5016915_10307,searchweb201603_54,ppcSwitch_5&algo_expid=59fd557c-2a8b-4d3c-b18b-09a3b3d9d46a-1&algo_pvid=59fd557c-2a8b-4d3c-b18b-09a3b3d9d46a&priceBeautifyAB=0 Fly
My tuxing runs a heck of a lot cleaner than my yong heng did and the black filter seems to be plenty for it. The yong heng would soak the cotton filter element with oil and water after about 30 minutes. The tuxing did not put out enough oil or moisture to notice when checking the filters after topping off my 30min scba tank from 3,800 psi to 4,500.
