  • Publication number: 20230149840
    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 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.

  • Patent number: 11247161
    Abstract: A support structure for an interior volume of a construction of pleated media is operably oriented in the interior volume and structurally supports the media. The support structure can pass directly through an innermost 60% of the interior volume. It can have a void volume not more than 80%. It can be inner liner-free and extend in a non-curved path. It can include a first sheet and second sheet of porous material. At least a first brace construction secures the first sheet and second sheet together and in spaced apart, opposing relation. The support structure can include a pleated construction having pleats extending in a direction non-parallel and angled to the direction of pleats of the pleated filter media. The support structure can be molded spacers.

  • Patent number: 9839870
    Abstract: A filter is includes a housing and at least first and second adsorbent materials within the housing. The second adsorbent material has different characteristic from the first adsorbent material and is in series with the first adsorbent material. When assembled, a labyrinth arrangement is located between a first port in the housing and the first adsorbent material such that gas travels between the first port and the first adsorbent material by passing through the labyrinth arrangement. A filtration system and methods for humidity control of a liquid tank head space uses a filter, including first and second adsorbent and a diffusion channel or labyrinth arrangement.

  • Publication number: 20110049015
    Abstract: A system and method for removing and managing water in liquid hydrocarbons is disclosed. The system and method utilize a water absorbent filter, such as one that utilizes super absorbent polymers, cellulose, cotton or other suitable material to remove water from the system that is either present as free water or as dissolved moisture within the liquid hydrocarbon. The super absorbent polymer filter can be regenerated through the introduction of a dried liquid hydrocarbon, through the use of an air drying system, or a combination of both.
