Abstract: The pressure relief assembly has a valve body constructed of breathable porous plastic. The valve body has an outer perimetric surface defining a detent mating surface and a sealing surface configured to form a seal around a valve opening. A first detent has a detent engagement surface configured to releasably engage the detent mating surface. The first detent is configured to release the valve body upon a minimum pressure differential across the valve body. The first detent is configured to extent laterally outward from the detent mating surface. The pressure relief assembly has a frame having a coupling structure configured to couple to an enclosure. The pressure relief assembly has a valve mounting surface and a valve opening within the valve mounting surface, where the valve body is sealably disposed on the valve mounting surface across the valve opening.

Abstract: A vent assembly has a vent housing having a first axial end, a second axial end, and an airflow pathway extending between the first axial end and the second axial end. An environmental opening is towards the second axial end configured for fluid communication between an outside environment and an airflow pathway. An enclosure opening is configured to selectively define a fluid flow pathway between an interior of an enclosure and the airflow pathway. The vent assembly has an obstruction having a first relative position and a second relative position. The obstruction is configured to obstruct the fluid flow pathway in the first relative position and unobstruct the fluid flow pathway in the second relative position. Filter media is disposed in the vent housing laterally across the airflow pathway.
