Abstract
A vent assembly () has a vent body () defining a first end () and a second end (), a central axis extending from the first end to the second end, and an inner surface defining a cavity. A first retainer extends across the cavity towards the first end of the vent body, and a second retainer () extends across the cavity towards the second end of the vent body. The first retainer defines a first retainer opening extending to a first radial distance from the central axis, and the second retainer defines a second retainer opening extending to a second radial distance from the central axis, where the second radial distance is greater than the first radial distance. Coalescing filter media is disposed in the cavity between the first retainer and the second retainer. The coalescing filter media, the cavity, the first retainer, and the second retainer cumulatively define an airflow pathway.
