Sun-Mar Excel NE Compost Toilet - White
Item#: 2460005

The Sun-Mar Excel NE Compost Toilet - White has long been the standard toilet for those living off the grid. The Excel-NE is a high capacity non-electric composting toilet. This composting toilet incorporates a patented Bio-drum which ensures a fast and odorless decomposition. The Excel-NE is the preferred self-contained model for heavy cottage or for residential use.

The success of the design meant that a three chamber unit could be specifically designed for those with no continuous 110 volt supply. The Excel NE has no fan or heater. Odorless operation is achieved by a 4" vent mounted at the top rear of the unit which acts like a chimney on a wood stove. For good air movement the vent should be installed vertically and to 2-3 feet above the peak of the roof.

By using this toilet you will save thousands of gallons of water, while recycling waste into safe usable soil. The unit is shipped fully assembled. To install, simply connect the supplied 4" vent stack and security drain.

  • Seasonal capacity: 5 adults or families of 7
  • Residential use: 2 adults or families of 3

Please note: The optional 12 Volt Fan should be installed if you need to install the toilet with any bends in the vent. No more than 2 45° bends are encouraged, even with the fan. If the Excel NE is used residentially or heavily, or is in a place which is subject to downdraft, the optional 12 volt fan should be installed in the vent stack. This fan draws 1.4 watts and can be powered by a solar panel and 12 volt marine battery.
