... vortex filter dual flow Cummins 5.9L diesel, very nice filter

This has about 8,000 miles on it. Nothing wrong with it.

It has a vortex cone in the upper element, the second element does extra fine filtration
The rubber seal is perfect between each element
Metal can is decently strong

looking down from top into first element has this cone

The lower element is a fine filtration, and you can feel the difference with your fingers.
All the pleats are nicely shaped. It is not deformed at all. The bottom coil spring is strong thick wire.
Apparently, I did not take a pic of it
First picture shows the order of assembly
There is no drain back rubber flap in top plate.

This is a LARGE! filter and very long

Same style filter is this

Info from another poster on how it works.

Spoke to Cummins (800) 223-4583 on three separate occasions with three different tech support people (Rosalie, Judy, and Jeff), and the Venturi Combo Lube Filter WILL work on our Cummins engines. In fact, the filter was designed specifically for the 5.9L engines used on Kubota and Carrier. These are NOT Kubota engines…they are Cummins 5.9L engines, and they are the very same engine in our Dodge trucks. The filter will also work for the 6.7L. The reason Dodge does not officially approve it is they felt they would not be able to recoupe the cost of paying Cummins for licensing of this product on their trucks. Or perhaps it is because the Venturi Combo it is an extended change oil filter, and maybe they thought they would loose money selling their conventional filters if they also sold this one. In any case, it’s a great product…screw on replacement approved by Cummins, no additional components to fail, no exposed external hoses, no parasitic pumping loss, no oil pressure loss issues, extended oil AND filter change intervals, and a clean simple install.

Here's how it works. Conventional bypass oil filters work by using the pressure differential from the high pressure side of the pump and the near zero oil pressure side in the sump (where the oil is dumped), which helps force the bypass oil through the filter medium. A negative aspect of this design is that the 10% of fluid used in the bypass side results in parasitic pumping loss (usually not a problem, but it can be). The Venturi Combo does not have any parasitic pumping loss because oil is not bypassed into the sump. It works by forcing the highflow oil through a venturi, which increases velocity, causing a pressure loss on the downstrem side of the stacked media section of the filter. This pressure differential pulls oil through the stacked media like a conventional bypass system. The "bypass" oil (it not really bybassed, since it reentered the engine instead of going into the sump) then enters a diffuser (expansion chamber) which decreases velocity, increaing the oil pressure back to its original level. Thus, there is never any parasitic pump loss…its really quite ingenius.

Cummins told me that the extended change interval is 5000 miles beyond what your owners manual calls for, then test the oil, and if it is still good, you can run another 5000 miles. I run Royal Purple, so my oil change interval is every 15,000 miles, and I change my filters every 5000. With this filter, you can also change your the filter once every 15,000 (I'll test it too). Less labor/time, and its cheaper in the long wrong. The best price I could find for these was about $32.24 from AgRepower. A Dodge standard filter costs about $12-13 each. Three of these (one every 5K) is $36, vs. $32.24 for one Venturi Combo. The part number is LF9028. Just google it to find some vendors. Here's the Cummins link for more info:

An oil filter only needs the ADBV at the base plate where the inlets holes are. It's a nice filter design with the dual elements. The specs linked to on the Baldwin website shows efficiency to be: 5 Nominal, 20 Absolute which is 50% @ 5u and 98.7% @ 20u. That's the efficiency of the filter as assembled. The efficiency at 5u is better than most high efficiency filters, so most likely due to the 2nd fine element in the filter.

And an advantage of dual filter is it won't clog up with fines and force the engine filter base to open its pressure relief valve which on the Cummins is set to 8psi. When it goes into bypass, the oil is not being filtered
If it had just one large fine filter, that could happen and you won't know unless you have a real oil pressure gauge, I hear the OEM gauge is somewhat calculated. Guy on the Cummins forum said it happened to him on a DBL 7349

But I have noticed the new oil on an oil change, the gauge when engine is cold reads higher.

Installed a DBL 7349 last Oil change and lead to this >

A real Oil psi Gauge saved my Engine the other day.
The Alert for low psi sounded, looked to see 8.1 psi. The idiot Dash Gauge shows a needle below 40psi.
Was just idling along the gravel road to my house, so another 1000' and parked. Shut Truck off and restarted still 8.1 psi at idle, dash Gauge still reads a needle below 40psi.
Also at 1500 rpm only 8.1psi.
First thought was Fuel in Oil. No Fuel in Oil not over filled.
Wound up being a Clogged Oil Filter at only 7 months/approx 2200 miles.
New Oil and Filter and all back to normal.
 
Do you feel the Carrier is an equal to the Fleetguard and the Baldwin? Has anyone ever cut the Carrier apart? I have read that the lf9028 has a little better construction than the bd7317 but @ $30-$40 a bit steep.

I would say no; it is not in the same class as a dual flow/bypass style filter.

Its states right on it "Without the use of a bypass filter". That filter states it uses "synthetic media", which seems to be no more than say a Wix 57620XE/Napa Gold 7620XE for comparison's sake. The pricing online is up there near LF9028 pricing though it seems. Only way to really tell exactly what you are getting is to get one and cut & post the pics.

Seems the Donaldson had a lot of cleaning up to do from what the previous filters were letting through.

I'm using the 7349 on my own truck. That particular post is from 2017. It's a strange account because the Cummins 5.9/6.7 has a filter bypass valve (items 6-9) in the oil filter housing along with the oil pressure relief valve (item 4). If the filter plugged one would expect the bypass valve to do its job.

The original post claimed he cut it apart and all looked normal. I don't know how a paper/wire element would stand up to having full pressure (dictated by the other relief valve) across it and still look normal...which means the bypass valve did its job.
