How it Works
The Precision filter cartridge is a tightly would long fiber paper product made from specific trees that allow the absorption action of the long fibers to draw the water from the oil without surrendering the ability to filter the oil through its dense fibers. The paper has only been pulped once to maintain its strength but to allow the cartridge to be manufactured. The cartridge employs a 4 –stage filtration process. The main body of the cartridge is made from the long fiber paper described above which is rated to 3-microns absolute. Approximately half way down the cartridge, another 1 micron disk is inserted to help even further increase the cartridge efficiency levels. This disk helps to further reduce the ISO cleanliness levels of the oil and is especially helpful in engine applications that have soot issues, like the EGR engines.
Once passing through the 1 micron disk the third stage is another 3 micron filtration level (the bottom half of the cartridge) and then finally on the bottom of the PFS cartridge there is another 1 micron disk inserted (being the 4th stage of filtration).
So effectively, the oil passes through 4 different stages: 3 micron, 1 micron, 3 micron and 1 micron.
Change your Oil regularly has been ingrained into every owner of a vehicle or anything that has an engine that needs to be reliable for construction or transport. Changing that ingrained belief to the concept that bypass filtration works is very difficult to believe and to trust. However, if you break it down it’s really simple to understand.
- Oil is typically comprised of 85% base stock and 15% additives.
- There are two reasons you primarily change your oil. Because it’s dirty (contaminated) or because the additive package has depleted beyond it’s useful life.
- The base stock is primarily a transport medium for the additive packages that perform all the critical functions. It also can assist with cooling of the system.
- The additive pack contains essential components to help fight contamination, prevent wear metals and acid formation. Additives can include dispersants, detergents, oxidation and rust inhibitors, extreme pressure agents, acid inhibitors, pour-point depressants, metal deactivators, and anti-foaming and gelling agents.
- These additives are sacrificial in nature, meaning once required they are used up and do not exist any longer.
- By keeping the base stock clean, free of water (that helps form acid), drastically reducing wear metals and soot circulating throughout the system, the additives last longer as they are not required to perform as often as they would normally.
- With consistent oil sampling you can easily monitor the integrity of the oil and a qualified oil lab will indicate if the oil is good for continued use. The key indicators shown on oil lab reports for engines would be; Viscosity, TBN levels (acid), soot, wear metals and other additive components.
- The PFS on-board oil recycling unit cleans the oil as it flows, so while the engine is running it is being cleaned. PFS takes away probably the dirtiest regular maintenance operation and allows the mechanic to carry out a much more intelligent and thorough maintenance check in the same time period, leading to less down time and eliminates costly repairs while at the same time saving a substantial number of dollars.
- The Precision bypass filter uses a small percentage of the normal oil flow and directs it through a bypass loop. As it passes through the bypass filter, and before it returns to the normal flow, abrasive particles such as carbon, soot, wear metals and silicon (dirt) down to one micron size are removed, along with all water. The cleaned oil is then returned to the normal flow effectively in its original new condition. By removing these impurities as they occur,
- The Precision bypass filter prevents the buildup of acid and particulates and maintains the oil within its operating specification.
