    Sun-Mar™ | Centrex 2000 - M/F (Micro Flush) 240

    Manufacturer: Sun-Mar™
    SKU: SMC-2000 MFP 240
    Perfect for medium to heavy seasonal or light residential use, the Centrex 2000 allows for both a longer composting cycle, and larger waste volumes than the 1000 models. The increased surface area in the evaporating chamber coupled with the larger heating element also provides better evaporation on electric units.

    Choose the Product options below


    All Micro Flush Sun-Mar systems are down rated user capacity by one user.

    With the use of Micro Flush Systems a large soakaway is needed (2000mmL x 1000mmW x 800mmD)

    Sun-Mar Microflush Pedestal Models 510 & 511 

    Model 510 is a standard height toilet model with regular sized seats allowing for ease of use.

    Model 511 is a low profile model allowing for raised floor setups when fall on waste pipe is a problem and is a great option for children to keep their feet on the ground.

    The Sun-Mar centrex systems can take upto 4 Micro Flush Pedestals


    Add a wind-driven vent to create redundancy.
    The wind-driven vent will assist the fan under heavy wind conditions and keep the system going in case of power outage or fan failure.

    Select this reducing collar to adapt the wind-driven vent from 150mm to 100mm.

    Select this reducing collar adaptor to reduce the pipe further, from 100mm to 50mm. Compatible with this system.

    Note: to reduce to 50mm, the 100mm adaptor above is also required - leave selected.

    Note: systems with 50mm piping will require a mounting stay (not supplied).

    Extend your drain pipe to reach your soak pit/trench.

    The system is packed with 1 meter of 25mm leachate drain pipe as a standard.

    Most soakaways should be installed 3 meters away from the foundations of the structure but this remains circumstantial to the site.

    Run your leachate drain into a soak pit (vertical soak-away) or into a trench (horizontal soak-away).

    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 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.

    The Centrex 2000 features a 370-watt thermostatically controlled heater in a sealed compartment under the unit and the standard Sun-Mar 30-watt turbofan, with a 2" vent stack to remove evaporating liquid and fresh odors.

    The Centrex 2000 is supplied with a 1" drain hose which should be connected to the 1" drain at the bottom of the unit. 

    Whilst not as large as the Centrex 3000, the Centrex 2000 M/F (Micro Flush) 240 model still comfortably accommodates a seven-person holiday house usage, requiring only one compost removal annually. In a residential capacity, the compost will need to be dealt with more frequently.

    A 50mm vent and low voltage fan help to ensure that odors are dispelled with a minimal electrical draw.

    ELECTRICAL RATING Fan Watts (Required or Optional Hookup) 1.9 (Required)
    DIMENSIONS 730mm x 1200mm x 770mm
    FLOORSPACE REQUIRED Height to Bottom – Top of Waste Inlet Assembly 749m m Vent Inlet Center Distance From Rear – Left Side 305mm Height to Center of Top of Vent Outlet Assembly 597mm
