What's in your filter? Media types explained

Champion Laboratories seems to source some of their media from China & Italy. Dongguan Retop Filter Material Co. / Ahlstrom Munksjo Italia SPA. Looking at recent shipment information of raw materials.

If anyone is interested, I'm hosting a webinar on September 26th at 10:00 AM CST on the topic of filter media. Let me know if you have any questions in advance and I'll try to work that into the materials.

(Justin) on the zoom. Appreciated the presentation & excellent job! Couldn't find the link to sign up for future ones. Could you link it? Are they similar or different topics? Fleetguard offers great media tech.

Hey Justin! Thanks for taking the time to call in. Hopefully I did a decent job covering the material...it's a subject that can get deep pretty quickly, and that forum usually brings a wide audience, so I keep that in mind with the content.

Here's the training link on our website; we cover different topics month to month...lubricants & lube filters next month so I'll talk to some engineers on the question around bypass valve materials and look to cover that next month.

am informative post, thanks for taking the time!! years ago reading on machinery lubrication i remember they noted that the FILTER is as or even more important than the OIL! retired now + drive little so my filters are changed every 6 month + oils yearly using at least fake synthetics + my 2001 TT 225Q gets real synthetic, only 4.25 qt + 300 hp + tq for mostly summer fun drives with the top DOWN!!

Great presentation, really enjoyed it! Looking forward to your update on the anti-drainback valve question I asked :)
 
Actually missed out on the webinar due to work meetings, oh well, would have lots of questions to asked to the relevant topics discussed.

Here's the response I got from one of our materials engineers:

"I would agree with the comment that Silicone would probably be a premium to the Nitrile for an anti-drainback valve . Nitrile typically will have around 5 to 8% plasticizer in the compound. Over time in a lube filter, this plasticize will be extracted out of the rubber and make it harder and cause it to shrink, so the functioning of the valve will decrease over time, since it will lose flexibility. Silicone on the other hand does swell a bit with exposure to oil, and will become more flexible and will probably seal in anti-drainback valve. Silicone will be more expensive in cost, so probably why it is more seen in premium products.

My guess is that the design of the valve is key to using Nitrile in an anti-drainback valve. By making the flap in the valve thin enough, it will still maintain some flexibility and if the area of the flap is big enough, the fluid pressure will be enough to cause it to flex and seal, in application."

Correct me if I'm wrong, I can't help but to assume that your filters are positioned for OEM drain intervals & incorporating Silicon becomes less important as one aspect for using Nitrile instead?

That makes sense to me. If the filter is engineered for the OEM oil drain interval and nitrile gets the job done, silicone may just be an extra, unnecessary expense toward the cost of goods produced.

Would they not consider their synthetic media filters to be premium though? I would think it would make sense to use the silicone ADBV's based on that?

Yes, like the Stratapore and Nanonet media filters.

NanoNet is definitely premium...I suppose StrataPore is technically premium, even though we've been using it for the better part of 30 years at this point. Very few of our lube filter part numbers are made with the NanoNet nanofiber concoction today...plenty of melt-blown StrataPore products though. Really not sure what the answer is for nitrile vs silcone though...I just have to fall back on it must not really be an issue of concern with the performance of the filters we make for the applications and markets of our customers.

Yeah, totally appreciate that it's a different space. You and Donaldson do make a "premium" FL-1A equivalent filter as well as the FL-820S, the pair of which cover every Ford Windsor, most Modulars and most FCA/Stellantis HEMI engines.

I run the FL-1A equivalent on our boat:

And tried the FL-820S equivalent on our Expedition back when we had it, but the ADBV definitely leaked-down and caused startup noise that I didn't get with other filters, so I stopped using it. Haven't tried it on the HEMI's yet, as I've got a pretty good stash of the synthetic media FRAM filters at this time, but it's been in the back of my mind, as it would be a no brainer if they had the upgraded ADBV's.

What is the take home message with this thread? I'd like to know the "best bang for my buck" oil filter. I am a happy owner of a 2002 Lexus LS430 with about 100,300 miles. I'd like this car to last me another 10 years. I plan on changing the oil every 5000 miles. I put a "rare earth" magnet on the drain plug and on the crankcase next to the drain plug to "catch" all the metal pieces, whatever that's worth.
