The Centrex 3000 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 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 for emptying.
All Centrex 3000 electric units feature a 370 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. This heater assists in evaporation of liquids, reducing the
amount of effluent from the unit. The fan also removes any fresh odors
from the unit, ensuring odor-free operation.
All Centrex 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 is for use with a Sealand low flush toilet, purchased
For Sun-Mar installations, we recommend the 510 Plus as the unit of
choice as it has the size and appearance of a "regular" toilet.
They come complete except for the required 3" four (4) bolt floor
Sun-Mar offers a selection of 1 pint flush toilets for use with regular
Centrex 1000, 2000, and 3000 series central composting toilet systems.
More than one "1 pint flush" toilet can be installed with these units
if necessary. The constraint is the number of people using the system
rather than the number of toilets.
Using about one pint per flush, these ultra low flush toilets provide
all the advantages of a flush toilet while minimizing water usage. They
are ideal for use with Sun-Mar Central Composting Systems, but can also
be used with holding tanks, overloaded septic systems, and in RV's.
A simple foot pedal flush opens the water valve and gate when pushed
down, and fills the bowl with water when lifted. After flushing, a
small amount of water is held in the toilet bowl which is sealed by a
self-cleaning ball valve and teflon seal. Even gravity-fed water from a
roof tank is sufficient to flush a Sealand toilet. In winter they can
be flushed manually using a container if necessary.
The Sealand 510 Plus has a regular sized toilet seat. In some instances
extra height is needed to allow the toilet to gravity feed to the
composting unit. Where this is the case, the Sealand 511 Plus, a low
profile model with a 10" seat height, can be mounted on a platform.
Sealand toilets are available in either White or Bone.
