Dometic Sanitation Wall Holding Tank Series with VacuMAX Technology

Injection-moulded wall-mounted holding tank series with shared design for multiple toilet types, cutting install time, weight, odor and water use.

Injection-moulded wall-mount tanks for black water on boats with limited bilge space. Standard and VacuMAX models share one tank body design, contain 50% less plastic, have identical hose and mount locations for easy swap to support macerator, manual or VacuFlush toilets. The VacuMAX uses up to 75% less water, reduces blockages, reduces odor, and cuts solids buildup inside tank, while lowering noise and extending pump life - delivering sustainability, space savings, and consistent installation.
