The currently-described technology relates to a method of constructing an adsorbent assembly. An adsorbent material is enclosed within a housing. The adsorbent material that is enclosed in the housing is dried by allowing moisture to escape the housing through an injection opening defined by the housing. Water is injected into the housing through the injection opening. After injecting water into the housing, the injection opening of the housing is sealed with a substantially vapor-impermeable material. Adsorbent assemblies are also described.

Adsorbent assembly with customizable humidity for an enclosure

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.

Controlled moisture vapor transmission filter assembly for electronic enclosures

A breather bag filter assembly for use with an electronic enclosure, such as a hard disk drive enclosure containing a rotating disk, is disclosed. The filter assembly provides filtration of air entering and exiting an electronic enclosure through a breather hole. The filter assembly is a deformable sealed cavity that exchanges air with the drive enclosure as the air pressure inside the drive enclosure fluctuates. In one implementation of the invention the filter assembly contains three layers of material. Two layers of material form the exterior of the filter assembly surrounding a third layer that is composed of an adsorbent material.
