The Sun-Mar Centrex 1000 Non-Electric Central Composting Toilet System was recently re-engineered for better compost flow to include input doors on the left and an output door on the right. This output door is only open when the drum is rotated backwards to extract compost. Now also includes a larger finishing drawer, easier access for maintenance, and a redesigned access port which is secured by a catch.

Designed for light to medium seasonal use by families of up to 6 (4 adults), the Centrex 1000 Non-Electric is typically able to hold compost for the full season, and compost needs extraction only in the spring. It does not normally need a 12-volt fan for the 4" vent stack, but the fan is available above if needed (the fan is required where a bend needs to be installed in the vent stack). Includes a 1" drain hose that should be connected to the 1" drain at the bottom left of the unit.

The Centrex 1000 Non-Electric is designed only for use with one or more Sun-Mar Low-Flush Toilets (available separately above).

About Sun-Mar Composting Toilets

Sun-Mar Composting Toilets save more than 10,000 gallons of water per year, keep water clean for drinking and swimming by not polluting groundwater, and recycle human waste into safe, usable soil. And because their aerobic decomposition produces no sewer gases, they are odor-free! Installation directly into the bathroom is a snap because no water connection is required. Everything for installation and start up, including the vent stack, is included. Great for use in homes, cottages, weekend cabins, pool houses, barns, stables, workshops, or off-grid applications - anywhere you want to minimize your ecological footprint.
