A lavatory drain system is disclosed. The basin, containing a U-shaped drain channel, employs one of two draining embodiments. In the first, a drain plate divides the drain channel into two chambers, allowing for fluid communication between them through openings in the drain plate. In another embodiment, the drain channel forms the upper chamber while a pipe disposed below the channel serves as a lower chamber for fluid to flow to the drain. Further, the drain cap of the claimed system is configured to direct air about the basin. One embodiment utilizes a ridge protruding over one of the basin's sides to captures air and directs it to a return duct. In the other embodiment, a series of louvres located in an opening are used to filter water and debris from the air before it returns to the fan.
