Technical Examples

A filter system in which a housing and an environmentally friendly filter cartridge are coordinated to provide ease of change of the filter cartridge and reliable operation. The cartridge contains no metal parts and is readily incinerateable. The housing is provided with a number of "universality" features including a changeable bottom which allows the housing to operate as a fuel filter, a lubrication filter, or a hydraulic filter in different applications. The housing and cartridge are configured to provide support for the plastic elements of the cartridge to prevent crushing of the filter under normal and abnormal filter operating conditions. A key system associated with the cartridge and the housing provides assurance that the correct filter is installed for a particular application.
