Perfect for medium to heavy seasonal or light residential use, the Centrex 2000 allows for both a longer composting cycle and a larger compost waste volume
Featuring Sun-Mar's™ patented Bio-drum™ technology, the Centrex is a true composting system that processes the compost in two stages within the unit itself.
The Centrex 2000 A/F works on a mixing design to maximize its capacity and improve the composting process. The rotation of the BioDrum blends the compost inside of the Centrex 2000 until the counter rotation is required to empty with the auto-drop mechanism, which lets the compost fall into the collection tray.
The Centrex 2000 A/F is the waterless version of the popular Centrex range. In the A/F (AirFlow) model, the waste falls under gravity into the drum of the composter. In the case of the micro flush model the waste is transferred by the 500mL flush and multiple pedestals can be installed with one composter.
Multiple toilets are not possible with the AF model as a straight fall is required.
The Centrex 3000 A/F is a 240-volt unit as standard. The solar-compatible Centrex 3000 A/F NE version is a 12-volt (1.9-watt fan) version. See Link
The Centrex 2000 A/F is supplied with a 1" drain hose which should be connected to the 1" drain at the bottom of the unit. This drain hose ensures any excess liquids are removed to a small subsurface gravel absorption trench.
Whilst not as large as the Centrex 3000, the Centrex 2000 model still comfortably accommodates a seven-person holiday house usage, requiring only one compost removal before and after the Holiday.
In a residential capacity, the compost will have a different maintenance interval.

The Centrex 2000 A/F features a 370-watt thermostatically controlled heater in a sealed compartment under the unit and the standard Sun-Mar 30-watt turbofan to supply oxygen to the pile, with a 2" vent stack to remove evaporating liquid and eliminate all odors.
The increased surface area in the evaporating chamber coupled with the larger heating element also provides better evaporation on electric units.
When used seasonally by up to 7-9 adults, compost will normally only need removal annually each spring. In residential use, compost will have to be extracted more frequently.
When used residentially by up to 4 adults, some compost will need to be emptied into the finishing drawer once every few months.
