I saw this posted in another thread in the compressor forum:
Amazon.com: UP100® High Pressure PCP Hand Pump air Filter Oil-Water Separator for High Pressure pcp 40mpa/400bar/6000psi Air Pump (Black) : Sports & Outdoors
www.amazon.com
I don't know if it is legit and I don't have any first hand experience with that particular filter. Good luck on your search.

That Amazon filter looks nice but I’ve never heard of a drier with no desiccant in it to remove moisture. Maybe if that filter was in your deep freezer it would work to some degree. Perhaps packing it with molecular sieve would be better.
In scuba we used Grade E air. It was quite dry. Dry air in scuba is necessary especially in cold water diving because any moisture would be subject to adiabatic cooling and would freeze the moisture and usually result in one of the regulators freezing (normally) in an open “free flowing” condition. Which could result in running out of air. In skydiving and scuba, bad things happen when you run out of air.
Alkin’s and Bauers and others areequipped with driers and filtration to produce Grade E air but what I have never read was what does an airgun require to keep it clean an dry. I don’t know how tolerant they are to moisture accumulation. In scuba, regulators are supposed to be torn down and rebuilt every other year, but they are life support systems and fall into a different category.
Lucky are the guys that use nitrogen for their guns, they don’t have moisture concerns.
Testing air for dryness and oil particulate is no big deal but you need the test kit for sampling and then there’s the cost of shipping the sample and the fee for testing. We tested quarterly in the scuba industry, in the U.S.A. anyway.
The test requires air to flow through a filter (to collect oil entrainment) and a sample bottle for 10 or 15 minutes at a specific SCFM and pressure, so it has some demand on the compressor as well.
For as long as I have been reading on AGN (about 3 years) I don’t recall reading many posts of airgunners having moisture or oil issues with their airguns. How big of a problem is moisture for airguns ? Maybe that Amazon filter is entirely adequate for our addiction, and at a nice price, except for it being Amazon.
