Sun-Mar Centrex 3000 High Capacity Composting Toilet Electric
The Centrex 3000 utilizes a continuous flow design for very heavy cottage or medium residential use. With a continuous flow system, rotation of the drum moves compost along the larger and longer 3000 series drum, before it drops automatically into the collection housing at the end of the unit. Under normal operating conditions the drum will not have to be turned backwards for emptying.

All Centrex 3000 electric units feature a 370 watt 120 volt thermostatically controlled heater in a sealed compartment beneath the unit coupled with the standard Sun-Mar 30 watt turbo fan and 2″ vent stack. This heater assists in evaporation of liquids, reducing the amount of effluent from the unit. The fan also removes any fresh odors from the unit, ensuring odor-free operation.

All Centrex 3000 series units are supplied with a 1″ drain hose which should be connected to the 1″ drain at the bottom left of the unit.

This unit is for use with a Sealand low flush toilet, purchased separately. More than one toilet may be installed on this system if desired.
