No magic. The much smaller nanofibers just filter better than microfibers, hold more particles, and flow better as explained:

The paper is for air filters. Not directly applicable. else we'd be seeing depth media air filters, but we don't.
Similar synthetic nanofiber media. Similar results.

As for patents. No proof of workability is required. Perpetual motion machines have patents.
Means nothing.
Donaldson has proven the technology 20 years. You can prove it to yourself with extended oil drains and UOA.

AND, since the patent covers air filtration, how does it apply to oil?
Similar synthetic nanofiber media, similar results. Proven by 20 years of used oil analysis.
quote:
Is the spun coating tough enough to stand the flow regime?
. Of course. Proven for the past 20 years by Donaldson, 5 years by AMSOIL. Tested by Independent World Renown SouthWest Research Institute .

Compare and contrast:
Velocities
Volume
Fluid dynamics is what I am after
Particle make up
Forces applied by the fluid. (Consider air a fluid in this case)
These are automotive, truck and motorcycle filters. So the fluid dynamics would be in those ranges. Also defined by ISO 4548-12. Donaldson is the expert. The technology has proven itself for 20 years. Contact them for more details.
