Filter material

[Hurst89]

Would polypropylene wound filters collect soot very well? Or polypropylene melt blown filters? Or do I need to stick with cotton. Also, does anyone know if a 9 3/4" filter cartridge housing will accept a 10" filter? And lastly, would I need a steel core or can I get by with a polypropylene core? (polypropylene has a melting temp of over 200 degrees farenheit, but nearly all of the cotton filters with this core are only rated to 140-150 degrees). I am thinking I could coil some copper line to help cool the oil before it gets to the filter housing.

Oh, and how many microns will it take to effectively control soot?

 

[Gary Allan]

You want cotton wound in either case. You can use polypropylene if you can control oil temps to below 200F.

I use SS core cotton wound filters. The only advantage of poly filters is that you can burn the entire thing when done. With SS, you're fishing out the cores from the ashes.

You can order them in any micron rating that you want. 1um, 3um, 10um. The only thing that will change is the service life. The level you choose will be determined by how long you want your oil to last.

Don't want to hijack, but Gary, How fine of filtration can one go before we start filtering out the add pack?
Or is that just an "old wives' tale"?

 

[Gary Allan]

I don't think you can get that fine. I think even if you used membranes in the 0.25um a molecule would have to be HUGE (to quote a filtration engineer a PALL).

Here's an article (info-article-mercial) that puts it in perspective.

OK then thanks! I guess it was a stupid question.

Rant here...Pretty pathetic on my part since I got A's in my two required college Chemisty clases in the last year and a half. On the other hand, Professors tend to load you up with so much work that a student can slog through it with a good grade and hardly retain any of it.
Ain't college great?
Before I got into a degree program as an adult student, I always maintained that for all the good things about formal schooling, I would rather hire someone with brains and experience and "as needed" training for most jobs rather than some young buck with a degree. Now that I have seen the other side...Ha! Well, I still stand by my original opinion.
Rant done. Sorry to get way off topic there.

 

[Gary Allan]

No, I don't think it was a stupid question. I sure as heck didn't "KNOW" until it was confirmed by an upper strata dweller.

Your collegian career was to validate your ability to learn. It's a filtering process that also has socialization aspects to it. It's the time compression that gives you distinction over others.

It may take me 8 years to get the same degree that you have. I would probably know more about the various disciplines in the process.

 

[river_rat]

Good points, Gary.
As far as knowing the disciplines, Yes indeed. And I do occasionally have to instruct the Professors in the difference between idealistic acedemia and the way things really work out there, and sometimes even correct them on technical matters, too.
Many of them--all they've ever done is study and teach.

(I haven't got the degree yet. Three years so far and maybe two to go.)

Isn't it true that you need to get to sub-micron filtering to get soot particles? Unless they agglomerate, in which case the dispersants in the oil have ceased to function.

 

[Gary Allan]

I think it's more of a situation where the mass product is more than the dispersants can manage. Not that they've ceased to function. Otherwise, any sensible bypass filtration would be a total waste of time. The typical big rig OEM bypass filter is not all that fine. 10um would not be atypical. Then again, it could merely be due to the protocol of the single pass tests. It's hard to tell.
