    Sun-Mar™ | Centrex 3000 - M/F (Micro Flush) 240

    Manufacturer: Sun-Mar™
    SKU: SMC-3000 MFP
    The Sun-Mar Centrex system range is a split system, also known as an underfloor model. This means that the holding chamber is separate from the actual toilet pedestal itself. The major advantage of these systems is that they allow for greater holding capacity and therefore tend to be lower maintenance. If you have below-floor space for installation, then this is the range for you.

    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 medium residential use, the Centrex 3000 allows for both a longer composting cycle and the largest compost 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 3000 composting toilet works on a continuous flow design to maximize its capacity and improve the composting process. The rotation of the drum forces the compost along the length of the Centrex 3000 and into an auto-drop mechanism, which lets the compost fall into the collection housing. 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.

    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 the 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.


    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.
