          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

          A hardwearing Nano-Ceramic Non-Stick Coating is applied onto the inner side of the Pedestal (toilet fixture) for maximum cleanliness.

          Note; basic cleaning will still be required.

          Note; non-stick is hydrophobic and repels liquids only.


          Choose the fan voltage to match your power system.

          ABS pipe (US spec) is supplied with the toilet. This is suitable for straight horizontal vent stacks.

          If you'd like to adapt the unit to NZ pipe, please select this kit. You will need NZ pipe if you're looking to create elbows and bends.


          You may need additional vent materials depending on how many storeys your building has.

          Single Storey buildings with a high-profile roof (A frame or mono-pitch) require extra lengths of vent pipe - add one 830mm Vent Pipe Extension

          Double Storey buildings require extra lengths of vent pipe. Please add 4 x 1m Vent Pipe Extensions.

          Double Storey building with a high-profile roof (A frame or mono-pitch) require extra lengths of vent pipe - add one 830mm Vent Pipe Extension

          Kit for stepping the vent stack around the eaves of the roof. Allows you to avoid penetrating the roof.

          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.

          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.

          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.

          The Centrex 2000 NE (Non-Electric) is the non-electric version of the Centrex 2000 which is fitted with a 4" vent stack. Installation of a 12 Volt fan is optional, but it is recommended for heavy seasonal, residential use, or where the installation is particularly subject to downdraft, being surrounded by high trees or hills. We also recommend the fan if you need to install a bend in your vent stack.

          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 NE (Non-Electric) - M/F (Micro Flush) 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 100mm 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) 0.5 (Required) Amps
          DIMENSIONS 730mm x 1200mm x 770mm
          FLOORSPACE REQUIRED Height to Bottom – Top of Waste Inlet Assembly 749m m Vent Inlet Center Distance From Rear – Top Side vent outlet position
