Robert,
I understand the convenience issue, but what is the
basis for saying that the ADC screen traps particles far finer than a
paper filter? Have there been any
independents tests, or is this merely a manufacturer's claim?
The reason that I
ask is that the company that built my engine (Monty Barrett)
specifically recommended that I use a paper canister filter rather than a screen because the paper filter would
provide better filtration. I am not saying that the engine builder is
necessarily correct, but I am reluctant to depart from his recommendation
without some good data.
There is also a claim made in the advertisement
that it provides additional oil cooling (15-20) degrees. What is the basis
for this claim? What do your oil temps run?

Colyn,
I installed the ADC oil screen and have been very
pleased with it. (See http://www.aircraftspruce.com/catalog/eppages/adcsystem.php ).
100% of the trapped particles are right there on the surface and could be seen
at a glance. It traps particles far finer than a paper
filter. By-pass triggers an indicator lamp and there is provision for a
chip detector as well. And cleaning is a snap.

I did a little research on oil filters and
discovered that:
a) champion bypass pressure
differential is below continental spec
b) champion particle size is
40 microns which is right at expected film thickness. auto spec is 25
microns
c) in general, much higher
efficiency filters are available to the auto-industry
I'm wondering if anyone on the list has
experience with better filters.
thanks,
Colyn
