The Centrex 3000 AF (air flow) AC/DC is a new and improved 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 3000 series 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
When used seasonally by up to 8 or 9 adults, compost will normally
only need to be removed annually at the beginning of the following
season. If needed, additional collection chambers are available
for long term compost storage.
The Centrex 3000 AF AC/DC features a 350 watt 120 volt thermostatically
controlled heater in a sealed compartment beneath the unit coupled
with the standard Sun-Mar 30 watt turbo fan and 2" vent stack.
The Centrex 3000 AF AC/DC also features a 4" vent stack which
may be used to vent the unit when no electricity is present. We
also include a 12 volt 2.4 watt fan that we strongly suggest installing
in the vent stack, especially if you need to put a bend in the vent
as shown in the diagram.
The Centrex 3000 AF AC/DC is designed for use with a Sun-Mar Dry
Toilet. A pipe piece, 29" in length and 10" in diameter,
is supplied with the unit. The only restriction on installation
is that the Dry Toilet needs to be directly above the unit so that
there is a straight drop. This is long enough if the floor of the
bathroom is up to 35" above the surface that the composter
is placed on. The pipe piece can be cut to size and additional pieces
ordered if necessary.
All 3000 series units are supplied with a 1" drain hose which
should be connected to the 1" drain at the bottom left of the
unit. This unit should be able to evaporate all liquids while operating
in AC mode, with the heater on. Drains should still be connected
for heavy use or use in DC mode. Click
here for more information on handling excess liquid.
This unit is for use with a Dry Toilet
, purchased separately.
