Abstract: The technology disclosed herein relates to a filter element having a first endcap, a second endcap, and filter media extending between the first endcap and the second endcap. The filter media defines a central opening and is coupled to the first endcap and the second endcap. A filter cover is coupled to the first endcap, and a breather filter is integral to the filter cover. The breather filter defines a first flow face and a second flow face. The filter element defines an airflow pathway from ambient environment through the first flow face and the second flow face.

Abstract: A vent having a vent housing defining a mounting structure, a first opening between a first end and a second end of the vent housing, a first airflow pathway from the first opening, a second airflow pathway from a second opening, and a draining pathway from the first airflow pathway through the first end of the vent housing. The first airflow pathway has a first segment and a second segment extending in opposite axial directions. An inlet relief valve and an outlet relief valve are arranged in parallel between the first and second airflow pathways. The inlet relief valve opens upon exceeding a first threshold pressure differential of the second relative to the first airflow pathway. The outlet relief valve opens upon exceeding a second pressure differential of the first relative to the second airflow pathway. A filter assembly is disposed in the vent housing across the second airflow pathway.
