The Centrex 3000 AF (air flow) 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 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 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 38" above the surface that the composter is placed
on. The pipe piece can be cut to size and additional pieces ordered
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 particular model should be able to evaporate all liquids
as long as both heaters are on, and it is not being used heavily,
so an overflow drain may not be necessary.
This unit is for use with a Dry Toilet
, purchased separately.
