The vent stack(s) in your RV are there to exhaust fumes and gasses from the holding tanks. But what happens when air flows down the vent pipe? Sewer odors enter your RV. The 360 Siphon Roof Vent is designed to use wind from any direction or angle, from a light breeze to gusty high winds, offering a one way draw up and out the pipe regardless of wind conditions. It keeps the liquid in your holding tanks oxygenated, eliminating the need for chemicals to break down waste. Made of strong polycarbonate it requires no maintenance and installation is a snap.
