Perfect for medium to heavy seasonal or medium residential use, the Centrex 3000 allows for both a longer composting cycle and the largest compost volume
The Centrex 3000 works on a continuous rotation design to maximize its capacity and improve the composting process. The rotation of the BioDrum forces the compost along the length of the Centrex 3000 and into an auto-drop mechanism, which lets the compost fall into the collection tray. Unlike with the smaller Centrex 2000, the drum doesn’t have to be rotated backward for emptying. The drum handle can continually be rotated in a clockwise direction and allow the material to work along the drum and deposit in a separate collection box.
The Centrex 3000 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 3000 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.
This large Centrex 3000 model will comfortably accommodate an eleven-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 3000 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.
Listed capacities refer to the number of people, on average, using the unit per day. Do not pick a unit that is below your capacity.
The Sun-Mar Centrex AirFlow Systems come with Polymarble Palisade and Pandora fixtures options only.
