Default New style (spin on) Raycor (diesel) fuel filters


You're welcome, but this is not a place to show off that one can
properly open the correct box of filters.

Lets get back to helping simple boating folks to keep the crud and
critters out of their fuel and diesel engines in the simplest and most
efficient, less costly way possible, please.

As applied to simple plain vanilla fuel oil systems .... Ill stand pat
and depend on 35+ years of experience in engineering, design, tech
support, marketing, consulting, in high tech filtration and separation
technology, ... with the 'major' players and with the up-and-comers (&
some down and goners).

For the last time ..................

Now, show me either of:

A spun depth filter with "a 0.000000000002 micrometer" absolute
porosity,
OR

cant fathom hyperbole, and simplified exaggeration to attempt to explain
to the non-technical.


ANY spun filter with any absolute porosity rating.

Pall Profile, Osmonics Selex, are a few of the more common examples ....
last time I looked these were absolute to a beta 5000 efficiency which
would equate to a approx 1X10E7 / sq. cm. titre reduction (LRV) for "up
to" but not quite sterilizing requirements. Ya gotta remember before
macro-foam polymer membranes the industry used such things as potassium
titanate fibers, asbestos, etc. to effect single pass 'absolute' level
filtration.


The point is, you were wildly exaggerating,

No, I was being "mister wizard" to the Saturday morning science class.


If you *could* create a filter of the listed porosity, the surface
tension alone would create such a high pressure you'd never get any flow
at all. As you obviously know.

News to me, you must have had a 'public school education' ;-) ...
1. absolute visosity is the prime factor of viscous shear hence
differential pressure ... Ill stand on that statement, unless they've
recently changed physical chemistry, chemical engineering, and the laws
of fluid dynamics.


Never
had the fun of filtering thixotropic products eh?

Biological gels or protenaceous concentrations? .... about once every
3-4 months but with tangential filtration levels in the nanometer or
10000 Dalton range. I actually prefer viscoelastics.

If you want to take this offline, my professional fees are $175/hr.
