In 2014, Cummins Filtration ushered in the company's 56th year since its establishment. Looking back at the first product of the 50s of the last century, the “bag filter oil filterâ€, compared with the new product members in 2014 – CALF long-term filter that can effectively extend the service life of the oil, Cummins Filtration has become Commercial vehicle filtration technology leader.
The latest masterpiece: CALF long-term oil filter
In May 2014, the Cummins Filtration U.S. headquarters in Nashville, Tennessee, USA officially released its latest product in the field of oil filter filtration - Chemically-Active Lube Filters ( CALF ). Long-term oil filter. The CALF long-life oil filter (part number: LF17500) with a shape and size close to that of conventional products has been used first in Cummins' new ISG series heavy-duty engine platforms. Under the specified operating conditions of the ISG series engine, the LF17500 can help extend the service life of the oil to 100,000 kilometers.

Technical Innovation: Built-in Oil Enhancer Sustained Release System
The new product still uses Cummins Filtration star media StrataPore synthetic multi-layer composite filter as the main part of the filter. StrataPore filter applications make:
Filters have higher filtration efficiency while maintaining lower flow resistance to improve cold start performance
The filter has a higher volume of ash so that the oil filter captures more impurities and achieves lasting protection of the engine
In addition, the company’s latest patent, "Modified Built-in Oil Enhancer Sustained Release System," became the most noteworthy of this product.
With the use of Cummins certified engine oil, oil synergists with sustained release during use have been proven to provide ISG engine oil service life of up to 100,000 kilometers (in China, usually after heavy-duty engines need to run 20,000 to 30,000 kilometers Change the oil). This not only means that the user can reduce the number of maintenance in the case of reasonable use of the product, but also means that the CALF filter can save users a lot of money in the use of oil.
Oil TBN value
The oil synergist slowly released in the CALF oil filter is critical to extend the life of the oil. Through constant and timely chemical reactions, it maintains the TBN (Total Base Number) value of the oil during use to maintain a certain range, thereby ensuring the extension of the oil performance. In simple terms, TBN can be understood as one of the indicators for checking the qualification of engine oil. It measures the basicity of engine oil. As shown in the figure, traditionally, the TBN value of the oil will continue to decrease with the increase of mileage, and reach the critical point of TBN value at the time of 2 to 30,000 kilometers. Once the end-user does not replace the used oil at the critical point, the oil with a bad acidity will start to corrode and cause damage to the interior of the engine. In contrast, the application of the CALF oil filter (LF17500) effectively extends the time that the TBN value is maintained within an acceptable range, allowing the effective mileage of the oil to reach 100,000 kilometers. This means that compared to conventional engines that do not use CALF, the use of CALF filtration can save nearly 80% of the ISG engine's annual oil consumption.
Machine filtration revolution: win-win for end-users and the environment
The revolution in oil filtration brought about by CALF products means a win-win situation for end-users of the engine and the environment. End-users often derive revenue from the work of engine-related equipment. Without causing damage, users often want to increase output and revenue by keeping equipment operating as long as possible. The long life of the CALF long-term oil filter itself and its ability to help reduce the number of engine oil changes throughout the life of the equipment are designed to help users minimize downtime due to equipment maintenance. In other words, the benefits that end-users get from CALF applications are obvious:
As always, equipment protection;
A longer maintenance interval means longer equipment operation time;
Reduced maintenance costs resulting from fewer maintenance visits;
Significant savings in equipment life-span oil consumption.
On the other hand, "the birth of this new technology will also contribute to reducing the environmental burden," Liu Zhisong, chief engineer of Cummins Filtration's East Asia Research and Development Center, mentioned in describing this product. The large consumption of oil itself is undoubtedly an environmental burden. CALF oil filters save the amount of oil used by end-users while also reducing the burden on the environment. The win-win situation of the environment and customers is the driving force behind the birth of this revolutionary oil filter.
