Capacity: 5-7 people weekend/vacation use, 2-3 people residential/continuous use

Designed for those with no continuous 110-volt supply. The Excel NE has no heater in the base but features an insulated Bio-drum to maintain the warmth of the compost. If the Excel NE is used residentially or heavily, or is in a place which is subject to downdraft, an optional 12-volt fan should be installed in the vent stack. This fan draws 1.9 watts and can be powered by a solar panel and/or 12 volt battery. Evaporating capacity on the Excel NE is variable, so the 1" drain at the rear should be connected to an approved drain pit, container, or other facility.
