vanjuen,
Read up on the technology of Donaldson/Amsoil Nano Fiber media oil filters. The new media allows the filtration of particles down to 15 microns @ 98.7% efficiency, yet still free flow as well as your cheapest filters that only filter to 20 microns @ similar efficiency.
Nano filber filter media technology was developed by Donaldson for the M1 Abrams Tank. The military required air filtration that was able to filter the finest dirt particles in the deserts of Iraq, be cleanable in the field (no oil allowed), and flow enough air to allow the high horsepower turbines to breathe. They gave the military exactly what they were looking for, and more.
Shady,
Thanks for the pics.
feel free to use them any time,
I had even loaned my cutter to Sid for his filter "thread" he is working on. But he told me it will end up being a "filter study website"
