The Centrex 2000 A/F (Air Flow) NE is a low voltage, waterless “off-grid” alternative to the straight Centrex 2000 model. The system is designed for use in conjunction with a waterless toilet pedestal and processes waste under the bathroom floor, the non-electric system is slightly smaller than its electric counterpart.

Perfect for medium to heavy seasonal or light residential use, the Centrex 2000 NE allows for both a longer composting cycle and larger waste volumes.

The Sun-Mar Centrex system range is a split system, also known as a under floor model. This mean that the holding chamber is separate from the actual toilet pedestal itself. The major advantages of these systems is that they allow for greater holding capacity and therefore tend to be lower maintenance. If you have below floor space for installation, then this is the range for you.
