No magic. The much smaller nanofibers just filter better than microfibers, hold more particles, and flow better as explained: http://www.asia.donaldson.com/...talibrary/050272.pdf . And patented: http://www.google.com/patents?...v=onepage&q=&f=false .
The paper is for air filters. Not directly applicable. else we'd be seeing depth media air filters, but we don't.
As for patents. No proof of workability is required. Perpetual motion machines have patents.
AND, since the patent covers air filtration, how does it apply to oil?
Is the spun coating tough enough to stand the flow regime?
Compare and contrast:
Fluid dynamics is what I am after
Particle make up
Forces applied by the fluid. (Consider air a fluid in this case)
