“multinational oil company I worked for evaluated”
Something wrong here ???

Well -many people have their income from oil and spare parts sale, so maybe those guys are not the most objective in this evaluation.
Both GM and Cummins have performed their own studies about this, and the conclusion in real life gain is;:

-3-5 times prolonged life of a Diesel engine
-extended oil life
-lower fuel consumption
-cleaner engine, etc etc

Mr Smiley,
I have been working with By-Pass filtration for the past 9 years and have tested many different products all of which offer some benifit one way or the other. As G2GREEN rightly noted, by surfing the net you will be amased how many new depth filtration suppliers there in fact are. In this regard, like most good full flow fiters, I have found that depth filtration in most instances is only as good as you manage and use them, and that in the end it boils down to cost effectiveness verses cleanliness and safe keeping of not only the lubricated component, but also the lubricant or fluid. I personnaly make use of Kleenoil Technology, and in fact manufacture my own depth filtration systems. Experiance has shown me that depth filtration works, and yes some better than others. The machines I work with have depth filtration on the fuel (diesel) engine, hydrualic, steering, and transmission systems. Engine oil drain intervals in some cases is as high as 2000 hour, with oil analysis reports still showing the oil fit for further use, while the hydrualic, steering and transmission oils are only changed by oil analysis, and in most cases have been in service for 10000 hr and longer. I also use depth filtration to filter final drives and differential oil which is maintained at an ISO cleanliness level as low as ISO 22/14/10. I HAVE MANY THOUSANDS OF OIL ANALYSIS REPORTS that confirm that the oil is still fit for further use, with additive packages still as good as new!!! To conclude, as the saying goes, "The proof of the puding is in the eating", thus what matters, is what works for you. I know that I have come in at a very late stage, and that you have by now already reached your goal, however, I would be please to share any information you may have to offer, or wish to request from me. Best regards

I agree with your comments about

"only as good as you manage and use them, and that in the end it boils down to cost effectiveness verses cleanliness and safe keeping of not only the lubricated component, but also the lubricant or fluid"

Bypass filtration, nomatter what brand, are not fit and forget type systems. UOA and intervention are key factors in the outcome of the benefits. Finding an proper UOA interval and Bypass element change interval must first be figured out by the tribologists at the lab and then changing the filter elements based on condition of the oil. I have used Kleenoil (www.kleenoilusa.ca) bypass technology and Divicia Polar filtration by GroupeLTI (www.groupelti.com) which are similar but different enough to apply them to a larger range of applications. Clutch/ Brake to turbine to diesel engine to hydraulic systems. I have never used Filtakleen but a former employer started with one as a demo and ended up having about 40 units installed on different equipments. How much personal attention by the distributors/rep and added value of service also have an affect on how much you get out of the whole package. I am pro-bypass filtration no matter what the brand is, I've seen lots of benefits come from the ones I have been exposed to. I know Kleenoil has about 5 or 6 sump capacity models where GroupeLTI uses just one but makes the difference up in the number of elements per application. I have one on my Harley Davidson.

I would be interested in FLAC GUARD's own version of a Bypass filtration system.

I thinks its about the issues of reliability, conserving oil and all the other benefits that can be gained and not about the filter manufacturers. Nothing wrong with plain old good ideas.

I even stopped to watch a company called Filtafry or Fliterfry clean french fry oil in a van set up with bypass filtration elements, pumps and a oil tank. The kid was doing it out front of the restaurant and I stopped and asked to see what the filters looked like. I could swear it was a Kleenoil or similar element. I had a good laugh.

My apologies for the long windedness but maybe someone will find an interest or at least look up some by-pass filters on the internet. Maybe even conserve some oil or something.

Best regards!

I would highly recomend Filtroil. Take a look at www.filtroil.com

Outside of a centrifuge, I see about 3 classes of bypass filtration. It always comes down to size/longevity/effectiveness composite.

Toilet paper bypass filters. Cheap and very effective. Short life. Cheap media.

Pleated filters: Limited only by physical size in longevity. Can be had to any level of filtration.

Depth media: This can be cotton wound ..synthetic ..whatever. Same size restrictions ..etc...etc.

There's no escaping the size/life/level triangle.

I concur with the comments of Kelly Tidwell.
Paper, 'bog roll' filters , please excuse UK terminology, will undoubtably remove Ca, P and Zn etc from the used oil as any debris removed must contain these elements as it is the additives function to keep engines clean and minimise wear, so these elements will be part of the debris as they have performed their task(spent additive). Well blended engine oils should not however be subject to additive removal by filtration.
When a used 'bog roll' filter was sectioned,it was found to be only dirtly on the outside layers.(see my previous comments)

I too have used bypass filration on high horsepower industrial engines with great success. I would like to install a bypass oil filter on my Cummins engine in my truck. It is shocking to me however how much the products cost. The housings are several hundred dollars and it is common that the elements are upwards of $50/ea. As simple as the devices are, you would think that a small mobile type system could be had for less than $100. Am I missing something?

My understanding has always been that the action of the additive pack in engine oils is irreversible except by chemical treatment so an offline filter set up would be ineffective as well as impracticable.

Perhaps we should seek a distributor in the US, our own systems are sold in the UK for around $400 USD installed and the elements for under $20. We don't sell many engine systems as we are primarily a hydraulic oil filtration company.

We are always told we live in rip off Britain, but perhaps things aren't as bad as we thought.

My company has recently started to experiment with one of our new LR10 and LR20 based systems used in the bypass line on injection molding machines. The testing performed so far indicates we can remove particles in the >2 micron range as well as any of the big traditional filters. The advantage we have over tradional filters is that our system can reduce submicron particles. This reduces sludge and varnish levels.

When we were at the test site, we were moving our machine to another molder when the shop manager saw us. He walked over and nervously said, you're not taking that back are you? We said no, we're just moving it to another machine. He replied, please don't take it. Our machines are running much better now.

His injection molder's oil started with a patch weight of 280 mg. Three weeks later it was 6 mg.

Dear all!
There are some special "filters" which are nor mechanical filters, but electrostatic ones which have some very important advantages! You kind find more at for example www.kleentek.de

I had assumed it was bad form to use these fora simply to advertise your products, but perhaps I'm wrong.

You could also look up at www.internormen.com. They do have good by pass filtration units of various capacities

I would recommend COMO Filtration Systems.

Filters remove both 10+ pounds of particulate and up to 1 gallon of moisture per filter, so you only need to stock one type of filter.
