Lubrication Filter - Oil Filters - Oil Filter Cartridges

Cummins Filtration - Fleetguard provides oil filters that meet and exceed OEM performance requirements for your engine.

An oil filter is a filter designed to remove contaminants from engines oil. Engine Oil filters in internal combustion engines in on- and off-road motor vehicles. In addition to motor oil, every engine needs an oil filter to help keep it running. While motor oil lubricates the engine, the oil filter stops the substantial deposits from reaching critical engine parts.

What does the oil filter remove?

The Oil Filter removes contaminants from the Lubricating Oil, which is the lifeblood of your an engine, without fresh oil your engine would rapidly stop working. Lube Filters remove impurities and the wear-causing contaminants from the engine’s oil, rather like kidneys purify the blood. If the Lube Filters are not doing an adequate job of removing contaminants, engine life can be radically shortened. Lube Oil not only allows the internal components of an engine to move by keeping the various parts separate from each other, but it also carries out many other critical tasks.

These deposits can result in dangerous levels of engine wear. We all know that as oil passes through the engine, it lubricates such parts as the valves, cylinder walls and pistons, camshafts and connecting rod and crankshaft bearings. As the oil flows over these various parts, it picks up small metal particles, dirt and other types of harmful grit. A good motor oil chemically holds these harmful deposits in suspension until it reaches the filter, where the deposits are trapped and removed from the circulating motor oil. Even though the oil pump pickup tube has a screen that removes large particles, the oil filter is still responsible for most of the filtering. Filter media is designed to trap the most harmful particles which rated between 10 and 20 microns. The Oil Filter captures these suspended contaminants the first time they reach the screen. The wear particles suspended in the oil range in size from 10 to 20-micron size range. These wear particles are forced through the oil passages of your engine. These dirt particles can rip and gouge bearing and cylinder surfaces. A high quality engine oil filters remove more debris from the oil then the low priced filter. Longer engine life is the primary reason why using a premium quality oil filter is so important. Test results have shown that particles under 20 microns in size cause far more engine wear than larger size particles. Particles less than 10 microns remain suspended in the oil, so wear surfaces in the engine are protected. Large particles (over 20 microns) will not fit in tight engine spaces. They usually remain lodged in crevices, until oil pressure breaks them up into smaller particles. Therefore, a filter that traps and holds more particles in the 10 to 20-micron size offers better engine wear protection. Types of Oil Contamination: The pollution in the oil that the filter must remove is produced both inside and outside the engine. Internal contamination is caused by tiny metal particles that typically wear off the moving parts of the engine. External contamination is due to the abrasive dust and dirt in the air that enters through the air intake system, as well as the fuel system and its by-products. A top quality filter oil filter can handle both kinds of contaminants.

A top quality oil filter can handle both kinds of contaminants. Today's High-pressure fuel injection systems produce much lower exhaust emissions than previous diesel engines. However, they do provide higher levels of soot in Lubricating Oil. The soot will tend to create what we call sludge, a black, almost gelatinous, sticky material which can be abrasive, resulting in increased wear rates that can quickly block a filter. In this case, the bypass valve will open, sending caustic, unfiltered oil to the moving parts of the engine.

Two main types of oil contamination must be removed by your engine's oil filter. These types of oil pollution are produced both inside and outside the engine.

  • Internal contamination is caused by tiny metal particles that usually wear off the moving parts of the engine.
  • External contamination is due to the abrasive dust and dirt in the air that enters through the air intake system, as well as the fuel system and its by-products.

A top quality oil filter can handle both kinds of contaminants.

Cummins Filtration exclusively designed StrataPore™ synthetic media in our Media Center for optimum performance and longer life. Unlike cellulose and microglass media, StrataPore™ is multi-layered, with an optimum number of layers for the desired level of particle removal.

The unique layering capabilities also allow StrataPore™ to provide nearly 50% reduction of filter restriction during cold start. With traditional media, pore size must be reduced, increasing the pressure required to force oil through the media. The smaller range in StrataPore™ media results in more repeatable, controllable filtration performance.
