Metal Fiber Filter Medium

Some people don't seem to care about leak gaps and torn media, which seems to be driven by some kind of fanboyism rationalization thing going on - seen it here many times. 🙃

Lets not forget to add a factually low effiecient synthetic filter media being marketed and sold as a premium filter. Sometime i really dont get German Engineering marketing, its mostly hogwash and has historically greatly contributed to their loss of world war 2.
 
One of my customers in Arkansas wanted to make spin on filters for a trucking company. They purchased a spin on canning machine from a company called Bubber in India. We purchased competitors filters for testing purposes to see what micron rating they were and how they performed. In several tests, we found that once the element got up to 16 psi differential, the media ripped open and the contaminant was allowed to go back into the engine and recirculate. Below is the graph comparing a celllulose spin on oil filter to a metal fiber element. At the time that the cellulose element failed, the celllulose dirt capacity was only 12.6 grams of contaminant. The metal fiber element had loaded to 40.1 grams at 16.3 psid.
Did these test filters have a bypass valve in them? Looks like the X-axis is mislabeled on the 2nd graph (g instead of mg).
 
I have been a filter designer for over 40 years....

And no training in the use of paragraphs?

Isn't mentioning anything political a violation of the board rules?

Unfortunately - the OP may have left the building …
Have you been to the website ? Seems they state 35 microns on the owner washable filters …

Nah ... I wouldn't use a metal screen filter on anything I have unless it was a full blown race car that got rebuilt all the time. I just noticed the x-axis on that 2nd graph. I mean 30,000 grams is 66.1 lbs. So it must be a misprint unless that filter is the size of a garbage can. 😄

Yet he is claiming his used oil is testing better than new …
Hope he comes back to answer questions …
Mostly curious - managed to find six OG Titanium filters - so set for a while anyway …
 
The OP said in post 1:

"We had been using a material called sintered metal fiber. It was a random mat of 316L stainless steel fibers all sintered together into a pleatable filter media. This stainless filter media ranged from 3 micron up to 100 micron in filtration rating. Since it was 100% stainless steel.'

"After one year, I changed out the Mobil 1 oil since the acid number started to creep up but have not removed the filter. I send a fluid sample out to Wearcheck labs in Cary, NC every 6,000 miles to see how things are doing. New Mobil 1 is very dirty. It is around ISO 4406 Code 23/21/18. My car has stayed around 18/16/13 throughout the test which is cleaner than new oil."


So this special MIL Spec metal media doesn't seem to be the same as the metal screen type material used in oil filters out there on the market for automotive engines, which are typically advertised to be able to filter down to 30-35 microns. And if the metal stainless fiber (not a screen) material he's talking about is able to keep oil cleanliness to an ISO 4406 Code level of 18/16/13, then it's way more efficient than even say an OG Ultra which has shown to not achieve an ISO code that low in the UOAs on this board with PC data. So this is something way more high tech than the simple fine metal screen filters used on race engines, etc. The metal fiber media he's talking about sounds like typical oil filter fine fiber sized synthetic media, but made of metal that can be cleaned and reused.

Yeah, they are not selling Joe Driver what the Army gets …
(Nor would we pay) …
$300 for 35 microns is all I gleaned from www.com
