Sun-Mar Centrex 3000 Central Composting Toilet System
This item requires a custom freight quote. After your order is placed, we will contact you with shipping rates and will complete your order upon your approval.
The Sun-Mar Centrex 3000 Central Composting Toilet System utilizes a continuous-flow design for heavy seasonal use or medium residential use. The continuous flow system rotates the drum, moving compost along 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.
The Centrex 3000 features a 370-Watt, 120-volt thermostatically controlled heater in a sealed compartment beneath the unit, a 35-Watt fan, and a 2" vent stack. This heater assists in evaporation of liquids, reducing the amount of effluent from the unit. The fan removes any fresh odors from the unit, ensuring odor-free operation. Also includes a 1" drain hose that should be connected to the 1" drain at the bottom left of the unit.
Low-Flush or Waterless?
By default, the Centrex 3000 is designed for use with one or more Sun-Mar Low-Flush Toilets (available separately above).
To make the system waterless (dry flush), use the Sun-Mar Waterless Kit and one or more Sun-Mar Dry Toilets (available separately above).
