Abstract:
Thermoplastic bicomponent binder fiber can be combined with other media, fibers and other filtration components to form a thermally bonded filtration media. The filtration media can be used in filter units. Such filter units can be placed in the stream of a mobile fluid and can remove a particulate load from the mobile stream. The unique combination of media fiber, bicomponent binder fiber and other filtration additives and components provide a filtration media having unique properties in filtration applications.

US Classification:
210767, 210504, 210505, 210508, 210509
Abstract:
In the filtration of fluid materials, the removal of particulate from the moving stream requires substantial pressure to maintain flow and substantial capacity for removing particulate. The filters of the invention are rugged, high wet strength materials having a basis weight, permeability and efficiency suitable to obtain substantial reduction in particulate loading from liquid streams without plugging or mechanical failure. In particular, the filters of the invention permit the removal of substantial proportions of particulate from non-aqueous streams including lubricant oils, hydraulic fluids and other contaminated streams.

Thermoplastic bicomponent binder fiber can be combined with other media, fibers and other filtration components to form a thermally bonded filtration media. The filtration media can be used in filter units, such as breather caps. Such filter units can be placed in the stream of a mobile fluid and can remove a particulate and/or fluid mist load from the mobile stream. The unique combination of media fiber, bicomponent binder fiber and other filtration additives and components provide a filtration media having unique properties in filtration applications.
