Oil filtration is an integral component of equipment maintenance within a broad range of industries including automotive, power generation, manufacturing, oil refining, mining and more. Most of the traditional oil filter designs come in various sizes, dirt-holding capacities, filter media and cartridge types. It is important to select the right oil filtration systems to meet your unique environmental and operational needs.

We can characterize oil filters in terms of mechanism, filters contaminations or the method in which oil flows through the housing. Surface-type media is one of the techniques to control contamination in filters. Depth-type filters are specifically designed to filter a high level of contamination.

Filtration mechanism

Centrifugal filtration and magnetics are also effective contamination control techniques. In magnetic filtration, electromagnets are used to attract and filter ferrous particles as oil passes through a magnetic flux region. On the other hand, centrifugal filtration systems generate a centrifugal force for clearing contamination from oil.

The primary function of a filter is to remove and retain contaminants as oil passes through the porous part called the media. As the oil flows around, particles are impacted onto the filter media and held there. The gravitational effect allows larger particles to settle away from fluid flow. Contaminants become trapped at the surface of the media.

Best practices

In most cases, filters fail long before there expected service life due to improper filter handling and storage. Therefore, it is critical to keep filters clean and dry while observing other important maintenance activities.

The installation process looks simple and routine; nevertheless, it’s important to follow the manufacturers’ recommendations and procedures mentioned in the manual. One of the examples of ignoring installation procedures is over-tightening. It is often recommended that a three-quarter turn after seal contact is optimal. Under or over-tightening can restrain the seal’s effectiveness. Make sure the ducts, connections and seals are fitted in accordance with the best practices.

It is often not desired to pre-fill oil filters before installation. Installation of a pre-lube system is effective in diesel engines to counteract changes from dry-start conditions. In addition, many filters and filter housings are made to be interchangeable. However, just because a filter fits well doesn't necessarily make it an appropriate filter. It is the responsibility of maintenance experts to choose the best filters.

The role of a filter is not limited to trapping the machines’ undesirables, it also provides insights into what is happening within the machine. Maintenance experts or personnel involved in filter changing processes must be properly trained to implement the best oil filtration practices. Simple looking maintenance activities might be challenging for inexperienced employees.
