Filter warning ( amazon) for portable compressors

[SqrlHntr]

Might be old info to some, but Amazon sells filters that fit the Benj. Traveller compressor perfectly, but they are NOT nearly the same density or quality as OEM filters. After 1 fill, very damp ( way worse than normal) all the way through, and oil came all the way through the filter as well. Looks like the outer 3 mm was almost disintegrating. Spend the extra $ and get the OEM filters.

Thanks for the heads up

It bought these from Amazon and they fit my BJ Traveler. https://www.amazon.com/gp/product/B084P943ZT/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Of course the Amazon sourcing may have changed. They work equally well. I do change them out every 10 fills or so. I am filling a 217cc and 313cc tubes. If I had a bottle gun like a 450 to 500 cc, it would be more frequent.

Im laughing because what I purchased uses the EXACT same pictures and descriptions!

Must have been a bad batch or sourcing issues. Amazon is shady for sure.

Maybe I'm understanding your description of the situation incorrectly, but if nothing else changes with the compressor and atmospheric conditions I would think that the filter that is saturated as opposed to dry would be the better filter, no?

If compressor outputs 1 ounce of water during the fill and the Amazon filter is filled with 1 ounce of water, but the OEM filter is dry or mostly dry this tells me that the water must have went past the OEM filter, right? If not where did it go? Seems the Amazon filter, by your description, "trapped" the water and oil.

the Amazon filters were past the saturation point saturated after one fill . The OEM ones hold up for multiple fills and get damp, but not allowing anything past and not nearly to the saturation point like the Amazon ones. There is also an obvious density difference between the two. the OEM's are tighter and dont compress nearly as easily. The Amazon ones I received are, IMO way less dense and the fibers are not nearly as tightly compacted. if you pull them apart you can tell the fibers are not tightly woven as the oem's.

Weigh each (unused) and let us know what the difference is. And if you are energetic and want the real answer do the same fill with each. Same starting pressure, same rooms conditions, same ending pressure. Weighing each filter immediately after bleeding. This will tell you a lot more then just a visual inspection of each in an unused state.
