Porta Potti & Dometic Toilet Ventilation SOG Type C

No More Odors
A small, high-performance fan—developed specifically for and in collaboration with SOG (resistant to the aggressive components in the intake air from the waste tank | waterproof)—achieves the following effect

• It turns on automatically when the toilet flap is opened and creates negative pressure in the waste tank
• This creates a “SOG” effect at the valve opening, which draws in fresh air as well as the odors produced during use and directs them outside
• The intake of air acts as a seal and 100% prevents all unpleasant sewage gases from rising out of the tank (comfort without odor)
• However, after automatic shutdown, ventilation to the outside continues, while the system remains sealed inward

Advantages
In addition to eliminating odor nuisance, active toilet ventilation has the major advantage of requiring no chemicals whatsoever.
When the valve is closed, the SOG system’s hose connection to the outside ensures that the decomposition process is accelerated by the deliberate introduction of oxygen into the waste tank. Even standard toilet paper is decomposed in no time, eliminating the need for special paper.

Activated Carbon
An important component of the SOG and SOGII is activated carbon. It consists primarily of carbon (usually >90%) with a highly porous structure. The pores are interconnected, much like those in a sponge (open-pored). Activated carbon is used as an adsorbent in fields such as chemistry, medicine, water and wastewater treatment, as well as ventilation and air conditioning.

SOG and SOG II filters offer compelling advantages

• long service life (1 year)
• Complete neutralization of odors thanks to seamless construction
• no carbon dust generation
• low weight
• Compact dimensions
• Be sure to change the filter regularly, after one year,
• to ensure good air quality in front of the vehicle as well

Door variant

The fan is mounted directly inside the service hatch. The housing with the activated carbon filter is attached to the outside. The elegantly designed plastic housing is available in white, light gray, dark gray, and black, and can also be painted to match the vehicle’s color. SOG for the service flap is the easiest ventilation option to install.

Contents of the Complete Kit

• Fan motor integrated into the housing
• Exhaust hose with connector
• Adapter parts for connecting to the cassette
• Plug (for use when emptying the cassette)
• Wiring harness with switch for powering the fan (during use)
• Complete set of small parts for assembly
• Assembly instructions (very detailed)
• Filter housing in the appropriate color with activated carbon filter

Floor-mounted version

The SOG II Compact System offers a variety of options for ventilating the toilet. The unit consists of a replaceable filter cartridge into which the fan is inserted. This can be positioned flexibly—up to three meters from the toilet—and vented at any location above the floor (e.g., in the garage, under the bench, in the false floor, or in a storage compartment). For further routing, the gas-tight sanitary hose available in RV accessory stores has proven effective and is the easiest to install. The supplied parts are designed to work with a wastewater pipe system available at camping supply stores. For caravans where the toilet’s service hatch opens directly into the awning, we recommend installing the SOG II floor-mounted version. The specially developed filter unit is so efficient that the odorous air being extracted is completely neutralized. SOG II thus offers a ventilation solution that is not only easy to retrofit but also allows for a variety of installation locations. (Filter: 90 mm H, 110 mm Ø | Filter unit with fan: 160 mm H)
