    Abstract: A vent assembly has a housing defining a cavity, a first end, a second end, and a coupling structure towards the second end. A mounting surface is positioned between the first end and the second end within the cavity and defines a valve opening and a vent opening. A vent is coupled to the mounting surface across the vent opening, and an umbrella valve is sealably disposed on the mounting surface across a valve opening.

    Abstract: The technology encompassed by the current disclosure generally relates to membrane composites that can be used in acoustic venting assemblies. In one embodiment of the technology disclosed herein, a venting media composite has a microporous membrane layer and a coating on the microporous membrane layer to form a composite. The basis weight of the composite is at least about 0.5% higher than a basis weight of the microporous membrane layer without the coating. In some embodiments the composite has a decreased insertion loss than its membrane-only counterpart.

    Abstract: Taught herein is a venting media laminate having a microporous membrane layer, a fine fiber layer directly coupled to the microporous membrane layer, and a colorant disposed in the fine fiber layer. Also described is an acoustic venting assembly with a microporous membrane layer and a fine fiber layer having an average insertion loss no more than 100% more than the average insertion loss of the microporous membrane layer alone in the frequency range from 300 to 4000 Hz. Methods of manufacturing venting media is also described, where a colorant is added to the polymer solution which is spun to form a fine fiber layer. The fine fiber layer is laminated to an expanded PTFE membrane.

    Abstract: The technology described herein generally relates to a microporous membrane laminate for acoustic venting. In one embodiment, the technology disclosed herein is a polytetrafluoroethylene (PTFE) membrane having an average pore size between 0.05 μm and 2 μm and a scrim layer laminated to the PTFE membrane to form an acoustic membrane laminate. The acoustic membrane laminate has a thickness between 10 μm and 60 μm, and the scrim layer defines an average scrim opening between 0.20 mm2 and 5.0 mm2. The acoustic membrane laminate exhibits an increased average insertion loss in a frequency range from 300 Hz to 3000 Hz compared to the PTFE membrane alone, and has a decreased total harmonic distortion relative to the PTFE membrane alone. The acoustic membrane laminate has a water entry pressure that is substantially equal to that of the PTFE membrane.
