While we're on the topic of filters,

    Does anyone have any rough numbers for pressure loss/particle size
    across the various types of filters:
    fiberglass mat, paper, foam, foam and oil, other?

    Another question would be what size particulate are we concerned with?
    big and solid is obviously bad, dust storms also bad, do we need to
    go to
    electrostatic HEPA dust filters?

    Has anyone used large flat panel furnace filters?

    Thanks

    Sixty percent of wear comes from particles in the 5-20 micron
    range.  80% of
    engine oil contaminants come from the air.

    Consider the Donaldson Endurance media - a non-woven cloth.  Nearly
    the same
    pressure drop as a fresh K&N, with better particle capture than a
    seasoned
    paper filter.

Andy, that stuff looks pretty cool.  I have been struggling with how to
incorporate an air filter in my application.  This stuff may be the
ticket.  I could simply put a bunch of it in the up-stream side of my
intercooler...  ooo, that would be easy to do regardless of the media
type of material.  Any idea where to get nano fiber?

BTW, I ordered the new radiator.  No choice but to go with a 2-row.  I
kept the same exterior dimensions to make installation easier.  Volume
is going from 560 cu.in <http://cu.in>. to 900 cu.in <http://cu.in>!
(and airflow will go up by 50%).

Okay Dave what am I missing here, how does the airflow increase 50% ?
