The Centrex 3000 features a continuous-flow design suited for very heavy cottage use or medium residential applications. As the drum rotates, compost moves steadily along the longer 3000-series chamber before automatically dropping into the collection housing at the end of the unit. Under normal operation, the drum does not need to be reversed for emptying.

This system is designed for use with an ultra-low-flush toilet (sold separately), and multiple toilets can be connected if needed. It can also be converted to an AC/DC configuration with an optional conversion kit.
