Ordinary vent caps force odors to stay in the RV holding tanks, eventually causing them to seep into your RV living space. That means you may be inhaling methane, ammonia, chemical fumes and waste odors. The RV-360’s aerodynamic design uses the wind to eliminate the high-pressure around your vent cap that holds those odors down in your RV. By spinning freely with the wind’s speed and direction, a low-pressure area is created, causing odors to rise up and out of your RV. The gas and foul air in your holding tank is then replaced with fresh, oxygen-rich air to encourage faster decomposition of tank solids. That oxygen-rich environment also restores full sensor operation, if properly maintained. RV-360 works full time, whether you’re moving or stationary. Versatile design works with both black and grey water tanks. Made of UV-resistant ABS plastic.
