dave just curious why no fram ph8a its the fl1a repalcement? nice job too.

 

I'll get a PH8A. I also need to get a Purolator and a SuperTech (Walmart). Let me know of others anyone would like cut open.

Dave

 

no way, wix all the way

I'm a Wix guy, too. I've got a case of 51773's. Maybe I'll get a 51515 for the comparison, too.

 

i cut open a walmart version the st8a and the quality was actually pretty good.

 

Can you measure it? I used a tread depth gauge, and stuck it down between the pleats, to see how deep the pleats are. Then, count the number of pleats (excluding the one with the metal clamp or glue on it).

Take the pleat depth, multiply by two, and then multiply that by the filter element width, and that will give you the surface area of the element.

I would be interested to see your findings!

i no longer have it sorry. but i may just swing by walmart and buy one. i think there was like 7.5 feet of filter in there. the pleats were 1/2'' or so.

 

Not to blow a hole in your experiment but your are judging filters by the quantity of filter, not the quality. A filter that has a lot of media may not filter as efficiently as a filter with less media. Questions you need to ask are:

What is the maximum amount of oil the filter will flow at temp? It doesn't do much good if the filter is going into by-pass at full pressure. Too much media can restrict flow.

At what micron level is the filter operating at when at temp? If a filter has miles of media but won't filter particles at 40 microns- it's worthless.

At what efficiency is the filter working? If a filter is only getting say 20 micron material at 50% of the time but will eventually filter these out at 80% with several passes thru the filter, is it better than a filter that has less media but catches down to 10 micron particles at 90% in a single pass?

Have you investigated the ASTM testing standards for filters?

Have you investigated the Beta Ratio for filters?

I threw the last two in there so you would have something to do while yer restin'. Then, when you have all of that figured out, tell everybody what the requirements would be of a current production Triton engine using a 930 oil in a normal environment. After that, you will have a pretty good idea of what a good filter is.

I can tell you are going to enjoy the research. The truth is out there. I think I been watchin' too much TV.

 

Flash, you're not blowing a hole in my experiment. It's simply the first phase to measure filter surface area. All of those questions that you listed are excellent, and I'll use them as I do my research.

Two of the filters, the Donaldson P169071 and the Baldwin B2-HPG, have synthetic filter media. These two filters don't have the largest media surface area, but they are very likely the most efficient of all the filters examined, in terms of removing debris from the oil.

So, you are right on the money! Surface area is only one part of filter quality, but it is an important part.

We'll try to learn all we can about FL-1A and FL-299 equivalent filters.

Stay tuned!
