Rated for five adults (or a family of 7 including adults and small children).

The success of the Excel design meant that a three chamber unit could be specifically designed for those with no continuous 110 Volt supply. First launched in 1981, the Excel NE has long been the standard toilet for those living off the grid. A 1998 redesign gave the unit a rounded look, and recessed the drum handle.

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 as close to vertical as possible.

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 1.4 Watts and can be powered by a solar panel and/or 12 Volt battery.

Like the Excel, all components have been continuously redesigned and improved over the years.
