The Green Kap Enviro-Vent eliminates rv holding tank odors forever whether you are travelling or parked. Ideal for RV’s, Campers, Motor Homes, Buses, Chemical toilets, Port-a-Potties and Marine toilets.
You don’t need to be a handyman to follow the easy installation instructions. The Green Kap Enviro-Vent can be easily mounted after the original cap is removed from the holding tank vent on an RV’s roof top, and it becomes the new cap.

This amazing new vent is designed to work as a true Venturi. It is designed so the forward opening always faces the direction of air movement whether parked or in transit. The air enters the vent and is then compressed as it is forced through the tube causing the air flow to speed up. This principle is the Venturi effect and it causes a low pressure area sucking the odors out of the holding tank, acting as a vacuum. The methane gas along with the unpleasant holding tank odors are sucked out.

Enzymes cause the natural decomposition of the solids and Oxygen is the food for the natural enzymes in the waste in your black and grey water holding tanks. By Installing the new Green Kap Enviro-vent you now have constant air flow moving through the holding tanks creating an oxygen rich environment and in this new oxygen rich environment these enzymes are constantly multiplying. Therefore, no more need for chemicals.
