360 Siphon Waste Vent

The 360 Siphon is designed very much the opposite of the conventional vent cap. Its patented design invites the wind from all directions and angles, channeling as much air as possible to its center.Any wind will create a low pressure, pulling out fumes. The design of the unit makes it physically impossible for high pressure or wind to enter the stack. Even when an RV is stationary, a slight wind will enable the 360 Siphon Fume Extractor to pull fumes from any holding tank.
