TANK VENT WITH A PLEATED MEMBRANE

摘要

The technology disclosed herein relates to a tank vent (100) having a housing (102) and a pleated, vapor-permeable microporous membrane (104). The housing (102) defines a first vapor passageway (224) configured for direct communication with a tank interior and a second vapor passageway (226) configured for direct communication with the atmosphere. The housing (102) also defines a tank mounting surface (108) is mountable to a tank housing and a media mounting surface (112). The microporous membrane (104) is sealed to the media mounting surface (112) and defines a tubular structure such that the first vapor passageway (224) and the second vapor passageway (226) are in communication through the microporous membrane (104).
