The Centrex 1000 NE composting toilet system is ideal for those who do not have electricity and want a unit for a light seasonal application. In light to medium seasonal use the Centrex 1000 is typically able to hold compost for the full season, and compost needs extraction only in the Spring.
The Centrex 1000 NE system does not normally need a 12 Volt fan for the 4″ stack, but a 1.4 Watt fan is available if required (where a bend needs to be installed in the vent stack, a 12 Volt fan is required). All 1000 systems are supplied with a 1″ drain hose which should be connected to the 1″ drain at the bottom left of the unit.
The 1000 system is designed only for use with the Ultra low flush toilet (purchased separately). This system can be converted to an AC/DC system using the AC/DC kit, purchased separately. Installations include, but are not limited to: cabins, cottages, homes, businesses, resorts, camps, treehouses and workshops.
The Centrex 1000 NE is certified to Standard 41 with the National Sanitation Foundation (NSF). Click here to view a list of Sun-Mar’s NSF certified products.
