By-Pass Filtration

By-pass filtration is used extensively in Europe on all kinds of equipment and is growing in the US. The concept is so simple and obvious, one wonders why it's not the "standard operating procedure" everywhere. Moving metal parts are designed with a small gap of 2 to 5 microns (typically) for oil film creation. Even if that works well, there will be particulate within the oil through normal use in the size range of 1 to 40+ microns. Only the particles in the 2 to 10 microns are troublesome because they just barely fin in the gap and "scratch there way through the gap causing wear and creating more wear particles. Some particles such as soot are harder than steel and are very abrasive. Typical "full flow" filters only off catastrophic protection because they only filter out particulate above 20 to 30 microns and above leaving the worst ones to do their damage. By-Pass filtration removes these 2+ micron particles-who wouldn't want to do that?


Traditional By-Pass filters are remote mounted needing a positive pressure source of oil and a neutral point to feed the filtered oil back to the sump. Next you need to find a good place to mount the canister containing the by-pass filter. I can provide these remote bypass filters when needed.


I'm most excited about a combination "full-flow" and "by-pass" filter made for larger diesel engines. The existing spin-on filter(s) are replaced with a permanent, cleanable full-flow filter with a replaceable bypass filter cartridge in the center. This unit is very close to the size of the existing disposable filter. Using this combo filter one can expect to lengthen out the oil change interval by 4 to 6 times monitored by oil analysis. Of course there are savings associated with less oil changes but less wear is the real pay-off.


If you really want to do "all you can do" to lengthen the life of you equipment, combine the benefits of both by-pass filtration and Power Up Lubricants. you can expect oil change intervals to perhaps be doubled again to 8 to 10 times what they are now, confirmed again by oil analysis. See the illustration below . . .
