Fluid filters, also called liquid filters, are responsible for continuously cleaning the fluids (also referred to as lubricants) in an engine or machine compartments by removing, or filtering out, particulate contamination from these fluids. When the recommended filters are used and the recommended maintenance intervals are followed, the particulate contamination in the fluid is reduced resulting in the following:
Reduced component wear
Protection of moving components and low interference with clearances
Lower engine or machine downtime
Enhanced performance
Preservation of the reliability and life built into the engines or machine componentsThis section in this Special Publicationprovides a description of the construction and components of fluid filters and the measurement of the performance of filters.Fluid filters available in the marketplace vary significantly in quality and performance. Knowing the quality of filters from visual observation is not possible. Cat filters are of high quality and hence offer improved value and protection for the machine. The initial cost of a high-quality filter is expected to be higher than a poor quality filter due to the amount of media, quality of media and overall construction of the filter. The overall value of the filter includes initial cost of the filter, value of equipment protection, reduction of downtime of equipment, and extension of equipment life. As a result, the lifecycle value of high-quality filters outweighs the initial difference in cost.Cat offers two distinct types of fluid filters:

Spin-on FilterSpin-on Filters - A single filter part that is used once by spinning onto the filter base. The entire filter is disposed of at the end of the filter life. Spin-on filters are common and simple to maintain. In general, small Cat engines use spin-on fuel and lube filters. Some new small engines have moved to cartridge filter designs.

Cartridge FilterCartridge Filters - Cartridge filters are composed of separate filter elements and housing unit. The housing is retained and used for the life of the vehicle and the filter element cartridge is changed at the end of each filter service life. Cartridge filters eliminate waste since only the filter element is disposed of and the metallic housing is retained and reused during filter maintenance. In general, large Cat engines use cartridge filters for fuel and lube applications.Details are provided in this Special Publication, "Fluid Filters Components".Caterpillar offers a variety of fluid filters for applications in all Cat machines and engines. This Special Publication provides guidelines for using the filters. This Special Publication also details the design and quality built into the various Cat filters.Cat fluid filters are designed with optimized capacity and rating for Cat equipment. Cat offers fluids filters of three efficiency levels:
Standard Efficiency
Advanced High Efficiency
Ultra High EfficiencyDetailed information on the capacity and rating of the various fluid filters offered by Cat is given in this Special Publication, "Filter Capacity".Note: Substituting a higher-efficiency filter than recommended is typically safe. Substituting a lower efficiency filter than recommended is not acceptable.Caterpillar has introduced a "Plus" (+) designation for some filters. The "Plus" designation indicates an improved performance characteristic. Any of the
