Vacuum Toilet: The VacuFlush toilet operates differently as compared to other toilets. VacuFlush systems use a small amount of water (from as little as 400 ml) per flush in addition to a powerful vacuum. The toilet is connected to a pressurized fresh- water system. Because a vacuum generator is located between the vacuum toilet and the waste holding tank, the result is an odor-free bathroom compartment. VacuFlush toilets are equipped with an integral anti-siphon vacuum breaker which prevents the possible contamination of the fresh water supply.

Vacuum Generator: The vacuum generator creates the vacuum required to move waste from the toilet to the waste holding tank. It combines a vacuum tank and a vacuum pump in one unit. System vacuum level is monitored by a vacuum switch located on the vacuum tank. When this switch senses a drop in vacuum in the system, it automatically signals the pump to energize and bring the vacuum to oper- ating level. This process is normally completed in less than one minute. The vacuum pump design is both an efficient air and liquid pump that handles solids without a problem. It has two duckbill valves on each side of the pump chamber to maintain vacuum and prevent backflow of waste. It is manufactured of long-lasting polypropy- lene and draws only 4 to 6 amps of current at 12 volts DC.

VacuStat® Status Panel: The status panel is mounted in the bathroom. A green light indicates that sufficient vacuum is available for the next flush. The red light indicates that the vacuum is building and the pump is running. The red light also indicates that the holding tank is full and the pump has been deactivated until the tank is emptied.

TankWatch® Level Monitor: Includes four tank level indicator lights – Empty, Low, Mid and Full, and international symbology of four tank levels. One light is always on to indicate that system is operating. Panel is connected to three (Empty, Mid, Full) probes in holding tank. No electrical components come in contact with waste or water. Operates on 12 or 24-volt DC. Uses only .017 amps at 12 volts.

VacuFlush Shutdown Relay: To prevent overfilling of a holding tank, a shutdown relay is supplied as standard with the TankWatch panel. The relay shuts off power to the vacuum generator when the holding tank reaches the "Full" level, preventing overfilling of the holding tank.
