Filtration Performance A good filter is designed to perform well in a number of areas. When choosing an air or oil filter, three main filter characteristics should be considered.
The first of these is flow. The filter must have the ability to flow an adequate amount of air or liquid for normal application operation.
The second consideration is the usable capacity of the filter. The filter must have adequate contaminant-holding capacity to remain in service for an acceptable period of time. Finally, a filter's efficiency refers to its ability to adequately remove contaminants of a size critical for the application.
When considering filter performance, remember the flow vs. efficiency compromise. A filter that is very open and free-flowing will generally have poor particle removal efficiency. Conversely, if a filter has excellent smallparticle removal efficiency it will generally be more resistant to flow and have a relatively short life expectancy.
AMSOIL Ea Filters employ a number of mechanisms to mitigate the flow vs. efficiency compromise, including specialized design techniques and sophisticated materials and filter media.
