Abstract
A filtration media that incorporates a static dissipative media layer for dissipating the static charge that builds up as a fluid, such a fuel, passes through the filtration media. The filtration media includes a filter media suitable for filtering fluid, and a static dissipative media layer. The static dissipative media layer has a surface resistivity level that is sufficient to classify the media layer as static dissipative rather than conductive.
Claims29
Filtration media comprising a filter media suitable for filtering fluid;
- and a static dissipative media layer, the static dissipative media layer having a surface resistivity level of between about 1×105 to 1×1012 ohms/sq.
A fuel filter comprising a filter media suitable for filtering fuel;
- and a static dissipative media layer, the static dissipative media layer having a surface resistivity level of between about 1×105 to 1×108 ohms/sq.
A method of dissipating static charge that results from fuel passing through a fuel filter media of a fuel filter, comprising incorporating a static dissipative media layer into the fuel filter adjacent to the fuel filter media, the static dissipative media layer having a surface resistivity level of between about 1×105 to 1×108 ohms/sq.
