I've been using mine about 3 years. 250 bar fills on this tank. As for documentation.... I couldn't say 
 
I actually am using a cotton filter (small gold housing) from a hand pump, and it just catches the tiniest bit of soot or debris. No moisture to speak of. 

The yong heng I have has a coalescing stage and drain, so the large one is redundant and possibly not even needed, but I like having it anyhow. Sometimes I run it outside, and humidity might be very high. 



As for the ebay ad, you should ask the seller to provide the documents. 


 
Let me start with my location, pretty much central in between Great Lakes, summer hot and humid and winter is cold and humid.

I did couple diy pre-filters and post-filters, smaller and bigger, tried pretty much just anything I could salvage from cheap parts, but I was just actually delaying the worst. End of last year season my gun picked up a nasty cough (inconsistency) and I toke it all apart to bits and pieces, wooow. What I have seen inside was collecting for some time.

Immediately purchased a filter from aliexpress, the biggest I could find, to save $50 or 100 bucks for filter I need to make air for a $3000 gun?

Also, I strip down the YH and added an independently running fan at the rear.
