摘要： An adsorbent construction for use in an electronic enclosure is disclosed. In certain embodiments the adsorbent construction comprises an adsorbent material and a polymeric material substantially surrounding the adsorbent material. The polymeric material regulates the flow of water vapor into and out of the adsorbent material. In example implementations one or more openings are present in the polymeric cover, the openings permitting flow of water vapor through the polymeric cover. A filter material can cover the opening in the polymeric cover. The adsorbent material can comprise, for example, activated carbon, silica gel, or a combination thereof.

摘要： A filter assembly has a housing. The housing has an inner body and an outer body surrounding at least a portion of the inner body. The inner body has a base extending in a lateral direction and a first sidewall extending axially outward from the base. The inner body defines a cavity. The first sidewall defines a perimetric surface around the cavity. A first filter media extends across the perimetric surface and across the cavity. An adsorbent is disposed in the cavity. The outer body has a second sidewall laterally outward from and surrounding the first sidewall. The second sidewall spans at least 50% of the axial length of the first sidewall. The outer body has a first axial end and a second axial end and a retainer portion extending laterally inward from the first axial end. The retainer portion is positioned axially outward from the first filter media.

摘要： A liquid hydrocarbon filterability system includes a liquid hydrocarbon sample source piping in fluid communication with a liquid hydrocarbon sample container. A filtration media element is in fluid communication with the liquid hydrocarbon sample source piping. Filtered liquid hydrocarbon outlet piping is in fluid communication with and downstream of the filtration media element. A flow or volume measurement element is in fluid communication with the filtered liquid hydrocarbon outlet piping and is configured to measure an amount of liquid hydrocarbon passing through the filtration media element. A constant pressure source is configured to provide liquid hydrocarbon to the filtration media element at a constant pressure.

摘要： A gas replenishment component for an electronic enclosure is described. A main body defines a containment volume. The main body is sealed about the containment volume. A charging gas is contained in the containment volume. The containment volume has less than 5% N2. The main body defines a diffusive area that is permeable to the gas. A reversible seal obstructs the diffusive area.

摘要： The present technology is generally related to a filter assembly. The filter assembly has a first layer has a base layer defining a first perimeter region and a region central to the first perimeter region. A first adhesive is disposed on a first surface of the first layer substantially within the central region, and first adsorbent beads are coupled to the first adhesive. A second layer has a first sheet of filter material having a second perimeter region, wherein the first perimeter region and the second perimeter region are bonded. A third layer has a second sheet of filter material having a third perimeter region, wherein the first perimeter region and the third perimeter region are bonded. The base layer, second layer, and third layer are substantially coextensive.
