A reliable source for Oil Filtration information and leading Oil Filtration Companies & Manufacturers.
Oil is the lifeblood of car, truck, and motorbike engines. Perhaps more importantly oil keeps industries running by protecting the equipment needed to produce the products we need in our daily lives. Whether in an automobile engine, or in industrial machinery, oil picks up a lot of contaminants which can cause enormous damage as it passes through. Oil filtration is the partial removal of these harmful solid particles from this critical liquid through a filter material. Read More…
Oil FiltrationOil filtration is the process of removing contaminants from oil. There are many different kinds of oil, and there are even more different uses for oil.

Industrial systems for filtering oil typically employ multistage filtration with coarse and fine filters. Oil picks up a lot of contaminants as it passes through manufacturing equipment and industrial oil filtration systems must be used to protect machinery. Dirt and other potentially-damaging matter have the ability to damage both this machinery and the company relying on it.
Types of Oil Filtration
Centrifuge oil filtration works while machinery is still running by monitoring its oil pressure. Based on its pressure at an oil inlet valve, a centrifuge oil filter begins to spin. The ensuing gravitational force pushes any particles toward the wall of the centrifuge bowl, while the cleaned oil returns to the machinery. Contaminants accumulated inside the centrifuge bowl are then routinely taken out by hand when the centrifuge oil filter is cleaned.
The removal of the hydraulic or lubricating oil contamination particles by a centrifuge oil filter does not rely on a filtration medium because it is not a barrier-type filtration device. The centrifugal force of the centrifuge oil filter eliminates particles according to their relative density, unlike a barrier media bypass filter, which only removes contaminant particles larger than the filter’s pore size.
In addition to increasing engine reliability, centrifugal force offers a way to remove smaller-sized impurities that contribute to engine wear since contaminants are filtered based on their density rather than by their size. However, a particle must be denser than the flowing oil in order to be captured by a centrifuge oil filter.
In a nutshell the vacuum dehydration oil filtration process heats up oil to a point where its integrity doesn’t break down, but water and other contaminants within it become steam. This steam is then suctioned away from the purified oil by a vacuum device. A vacuum dehydration oil filtration system efficiently removes contaminants such as free, emulsified, and dissolved water as well as particle and gaseous contamination from fluids with petroleum and synthetic oil-base materials. Even when tightly bound in an emulsion, this system will consistently remove water well below oil’s saturation point.
As part of the process, a circulation heater raises the oil/water liquid temperature to about 150°F (66°C) inside the device, which causes any water to flash steam from the oil and it is drawn into the system by a vacuum pump. The purified oil is then forced through the vacuum tower's permanent dispersion media (PDM). Since water's boiling point is lower than the fluid's temperature of 150°F in that vacuum, water, and dissolved gases are "boiled off," effectively “dehydrating,” or removing water, from the oil. The cleaned oil is then pumped back into a reservoir by an oil discharge pump from the vacuum chamber's bottom.
As the name suggests, bypass filtration is a secondary process used in conjunction with full-flow filtration. This filtration process is used to remove smaller contaminants not caught through full-flow filtration. The procedure works by taking 5% to 10% of the oil flowing to an engine on a “partial-flow” basis where it is filtered further through a more-efficient bypass filter. Bypass filters feature a large pressure differential, which makes the oil flow through them slowly and enabling the removal of soot and other tiny impurities not caught originally.
A full-flow system will feature a pump that distributes the oil from a filter to the engine bearings, after which the oil returns by gravity to the sump catch basin. For a dry sump engine, a second pump evacuates the oil that has reached the sump to a distant oil tank.
The full-flow filter's job is to guard against abrasion-related engine wear. Full-flow filters are the most-common type of oil filter used to catch and clean oil before it's circulated into an engine. Full-flow filters are crucial for engine protection because they must be able to capture and hold harmful impurities while having enough holding-capacity to only require maintenance at specific service intervals. As just discussed, a bypass filter may also be used in conjunction with a full-flow filter.
Benefits of Oil Filtration
From a cost perspective, it is less expensive to regularly filter oil so it can be used for a longer period of time instead of replacing it more frequently.
Oil filtration allows machinery to operate more efficiently.
Oil filtration produces cleaner oil, thereby reducing damage to equipment and ensuring its lifespan will be significantly increased.
Nowadays, everyone is environmentally-conscious. Using oil filters can help decrease the negative impacts of otherwise disposed-of oil on the environment.
