A pressure relief vent includes an enclosure and at least one blocking element. The enclosure defines an air flow channel through a thickness of the enclosure. The enclosure includes at least one guide member that defines a track oriented transverse to a depth axis through the thickness. The at least one blocking element is held within track and is translatable between a seated position and a displaced position. The at least one blocking element plugs the air flow channel when in the seated position, and the air flow channel is at least partially unobstructed when the at least one blocking element is in the displaced position. The at least one blocking element is configured to be moved from the seated position to the displaced position by positive air pressure on an interior side of the enclosure to permit outbound air flow through the air flow channel.
