SOG + SOG II Type D Thetford C400

SOG Type D Door Variant Filter Housing, compatible with all Thetford cassette toilet models with the model designation C400
Swivel toilet bowl and waste tank with or without wheels, 19 L.
No More Odors
A small, high-performance fan—developed specifically for and in collaboration with SOG (resistant to the aggressive components in the air drawn from the waste tank and waterproof)—achieves the following effect.
It turns on automatically when the toilet slide is opened and creates negative pressure in the waste tank
This creates a suction effect at the slide opening, drawing in fresh air as well as the odors generated during use and directing 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 operating entirely without the use of chemicals.
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 broken down in no time, eliminating the need for special toilet 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, and ventilation and air conditioning technology.
SOG + SOGII filters offer compelling advantages
Long service life (1 year)
Complete neutralization of odors through seamless processing
No carbon dust generation
Lightweight
Compact dimensions
Be sure to change the filter regularly—after one year—
to ensure good air quality in front of the vehicle as well

SOG DOOR VARIANT
The fan is mounted directly on the inside of the exhaust flap. 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.

Advantage:
The SOG for the service flap is the easiest ventilation option to install.

Type D
For all models in the Thetford C400 series
Filter housing available in white, light gray, dark gray, and black

Toilet odors are filtered out to the outside via a carbon filter mat, which is attached to the outside of the service flap using a filter housing.

SOG ROOF VERSION
With a special roof vent, we offer the option of venting SOG systems through the roof. The waste tank is connected to the roof vent via a hose.

The high-performance fan is located directly beneath the roof vent and ensures sufficient negative pressure even with a pipe run of up to three meters. The gas-tight sanitary hose, available from RV accessory retailers, has proven to be the easiest to install when retrofitting a roof vent. The supplied parts are designed to fit a wastewater pipe system available at specialty camping stores (also applies to SOG II).

The roof vent is maintenance-free, as no filter is required.
Retrofitting can be quite labor-intensive in some cases, which is why it is primarily used by manufacturers as original equipment.

Advantages
Elegant solution
Well-suited for original equipment
No maintenance required
No modifications to the vehicle wall

Type D
For all models in the Thetford C400 series

The SOG system is vented through the roof using a special roof vent. The parts we supply are designed to fit the wastewater pipe system available at camping supply stores.

SOG II FLOOR 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. Because the fan is mounted inside the filter’s seal, it is barely audible.

The SOG II offers the advantage that the filter cartridge can be flexibly installed in a wide variety of locations within the recreational vehicle and vented through the floor at any desired point (e.g., in the garage, under the bench seat, in the false floor, or in a storage compartment).A hose or pipe extension (up to three meters away from the toilet) can be attached both upstream of the compact unit and to the floor outlet to find a suitable location.

Since the filter unit is placed inside the vehicle, no modifications to the exterior of the vehicle are necessary—there is no need to coordinate with the exterior design.

The specific technical design of the filter housing in relation to the flow dynamics, as well as the resulting vast filter surface area and the composition of the activated carbon, work so efficiently that the extracted odor-laden air is completely neutralized.

Therefore, for caravans where the toilet’s service hatch opens directly into the awning, we recommend installing the SOGII floor-mounted version without hesitation. Emptying the cassette is just as easy as before: The exhaust hose is removed, and the now-open connector is sealed with the appropriate cap provided.
(Filter: 90 mm H, 110 mm Ø; filter unit with fan: 160 mm H)

Advantages at a Glance

Type D
For all models in the Thetford C400 series

Toilet odors are filtered out to the outside via a filter cartridge that can be installed in a wide variety of locations within the recreational vehicle—up to three meters away from the cassette (e.g., in the garage, under the bench seat, in the false floor, or in a storage compartment). Ventilation takes place through the floor.
