A device to remove dirt and other impurities from air, oil, or water.
The amount of contaminants a filter will hold before an excessive pressure drop is caused. Most filters have bypass valves which open when a filter reaches its rated capacity.
Method of expressing a filter's ability to trap and retain contaminants of a given size.
The porous device which performs the actual process of filtration.
An end closure for the filter case or bowl that contains one or more ports.
A ported enclosure that directs the flow of fluid through the filter element.
Filter Life Test
A type of filter capacity test in which a clogging contaminant is added to the influent of a filter, under specified test conditions, to produce a given rise in pressure drop across the filter or until a specified reduction of flow is reached. Filter life may be expressed as test time required to reach terminal conditions at a specified contaminant addition rate.
