  • Descriptive Overview
    Established in 2003, EnviroSystems Engineering and Technology Co., Ltd. is focusing on new type of vacuum drainage technology, sewage, and waste resources recycling technology, as well as ecological town construction technology. The EnviVac air flush toilet aims to develop a better alternative to a dry composting toilet which has no water consumption, while maximizing the available waste for resource recovery. Robust design with no maintenance needed. Differentiated from other manufacturers by a patented diaphragm valve without mechanical spring(s); less than 0.1L of water and only 1 Wh of electrical energy required per use.
  • Use Case Details
    Single stall: Air-flush toilet interface can be used in a single stall as a urinal, squat, standard, or urine-diverting toilet. EnviroSystems also offers treatment solutions for backend processing.
