Centrex 3000

The CENTREX 3000 is unique among the Sun-Mar’s Central units. It utilizes a continuous flow design for very heavy cottage or medium residential use. With a continuous flow system, rotation of the drum moves compost along the larger and longer CENTREX 3000 drum, before it drops automatically into the collection housing at the end of the unit. Under normal operating conditions, the drum will not have to be turned backwards for emptying.

All CENTREX 3000 electric units feature a built-in heating element and fan assembly. This unit is for use with a 1-pint, Ultra-low flush toilet, purchased separately. More than one toilet may be installed on this system, depending on needs and available space.
