Toilet-Vacuum Flush
A vacuum flush style toilet is available on select models. The
Vacufl ush® toilet operates in a different way from other marine toilets.
The system uses around 16 ounces per fl ush plus a simple vacuum to
complete each fl ush which is a substantial water savings over other
systems. The toilet is connected to a pressurized fresh water supply.
Fresh water is the key to an odor-free bathroom compartment. Selected
other systems use intake water from wherever the vessel is sitting which
may carry an odor. The Vacufl ush® units are equipped with a special
vacuum breaker which prevents the possible contamination of the
potable water system.
Vacuum Tank- This tank stores the vacuum energy used in the system.
When a switch senses a drop in the vacuum it automatically energizes
the pump to upgrade the vacuum. This process in on-going between
fl ushes.
Vacuum Pump- This unique bellows style pump is designed to handle
solids without a problem. It uses two duckbill valves on each side of
the pump chamber to prevent back fl ow of waste and vacuum.
Vacuum Generator- This unit houses the vacuum pump and tank in
one unit.
Holding Tank- Unit features polyethylene composition 50% thicker
than other holding tanks. A deodorant additive is required to keep the
holding tank odor-free.
In-Line Vent Filter- Available on select models the fi lter uses special a
charged fi lter media to remove odors and sanitize the vent system.
Fresh Water and Waste Monitor- Select vessels offer a monitor panel
to display the waste level.
Overboard Discharge Pump- An optional overboard discharge pump
vacates waste through the deck waste fi tting or a seacock (only used
beyond the 3 mile limit in the USA).
