The Sun-Mar Mobile was the first composting toilet designed specifically for use on boats and in RVs as a chemical toilet alternative requiring fewer pump-outs and providing odor-free operation.
This mobile composting toilet uses Sun-Mar's tried and true three-chamber system, but with some necessary adaptations for use at sea, on bumpy unpaved roads, or under other conditions prone to excessive motion. The finishing drawer is gasketed so no liquid can escape from the evaporating chamber. The air intakes are located higher up, with air directed down to the evaporating chamber. And a special drum locker ensures that the composting drum is held upright under all sea or road conditions.
The fold-away foot rest has spring-loaded legs and can be tucked away when space is at a premium.
An included 4-Watt, 12-volt fan is installed in the included 3" vent stack. This fan, (which is on its own circuit) is designed to operate continuously while the unit is in use. Activated carbon and zeolite filter materials in the fan box "scrub" the air of fresh ammonia odors.
Evaporation is aided by a 120W, 110-volt heater located in the sealed base compartment. The heater was designed to run off 110V power because a 12V supply (for the fan) is often available while the unit is in motion, while the 110V heater can be used while the vehicle is in an RV park or marina. There should be enough 12V battery power on the RV/boat to keep the modest 4-Watt fan running continuously, and it hooks up on a separate circuit to facilitate this.
Evaporation capacity is limited by the size of the heater, the surface area of the evaporation chamber, and the volume of air movement. Arrangements should be made to connect the Sun-Mar Mobile drains to an overflow container for proper disposal.
Customers need to supply their own deck vents, which should be constructed to allow adequate air movement while preventing seawater from entering the unit. While venting above deck level is recommended, some installations will require that the deck vent is flush with the deck.
Sun-Mar Composting Toilets save more than 10,000 gallons of water per year, keep water clean for drinking and swimming by not polluting groundwater, and recycle human waste into safe, usable soil. And because their aerobic decomposition produces no sewer gases, they are odor-free! Installation directly into the bathroom is a snap because no water connection is required. Everything for installation and start up, including the vent stack, is included. Great for use in homes, cottages, weekend cabins, pool houses, barns, stables, workshops, or off-grid applications - anywhere you want to minimize your ecological footprint.
