The 360 Siphon RV Roof Vent Holding Tank Vent Cap Generation 2 remove odors from the source, the holding tanks, and exhausts them out the roof vent before they have a chance to invade the RV living space. By design, the patented RV roof vent can only create an updraft, expelling odors and fostering an oxygen-rich environment to speed up waste breakdown. This roof vent acts immediately after installation in any wind condition (with or without a breeze) to provide the ideal environment for proper decomposition, so caustic chemicals and perfumed cover-ups are no longer needed.Note: This product may require up to 2 additional days for order processing prior to shipping
