Air Head Environmental toilet works simply. By
separating liquids from solids the volume of solid human matter is
significantly reduced. Air Head's approximate five-gallon capacity
means that up to a seasons worth of weekend use, may be held. (Based on
solid matter volume for two persons' use twice every weekend for five
months: 80 uses). A liveaboard couple can expect 60 uses (one month).
Much like a household toilet the Air Head Environmental
Toilet has a bowl and an actuator which provides a "flush". The main
difference is the Air Head Toilet's waterless operation. A paper bowl liner acts as a carrier for solid matter on its way to the solids tank.
With a combination of agitation and desiccation and
decomposition, solid matter is rendered non-offensive inside the large
tank. Additionally, the unit has an integral 12 volt fan that provides
a constant negative pressure to pull moisture out of the living space.
In many cases a noticeable improvement in air quality will be perceived upon opening the companionway hatch after lay-ups.
Liquids are collected in the smaller forward tank. Our
unit's liquid tank makes an otherwise unpleasant chore very easy thanks
to a convenient carrying grip. You don't have to become intimate with
the contents, and its wide mouthed aperture will keep the contents emptying smoothly into any standard commode.
The liquid tank will hold approximately four days use per person if used exclusively.
Additionally, the Air Head Environmental Toilet may be
integrated with an existing holding tank system creating holding
capacity for both solids and liquids far beyond what many medium and
small boat owners are used to. This is because the tanks take on no
flushing water and are free to hold just what they need to.
