RV Cyclone Sewer Plumbing Vent uses the power of the wind to draw holding tank odors out of your RV. Even a gentle breeze works with the dynamically engineered shape of the cyclone to create a powerful vortex that pulls odors up and away. It attaches easily to any RV plumbing vent. Rotates 360 degrees to follow the wind.
