SOG + SOG II Type D Thetford C400

SOG Type D door variant filter housing, suitable for all Thetford cassette toilet models with the type designation C400
Swivel toilet bowl and waste tank with or without wheels, 19 L.
No more odours
A small, high-performance fan – developed specifically for and in collaboration with SOG (resistant to the aggressive substances in the air drawn in from the waste tank and watertight) – achieves the following effect.
It switches on automatically when the toilet slide is opened and creates a vacuum in the waste tank
This creates a draught at the slide valve opening, which draws in fresh air and also the odours produced during use, channelling them outside
The intake of air acts as a seal and 100% prevents any unpleasant sewage gases from rising out of the tank (odour-free comfort)
However, after the system switches off automatically, ventilation to the outside continues whilst the system remains sealed to the inside

Advantages
As well as putting an end to odour 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 broken down in no time at all, making the use of special paper unnecessary.

Activated carbon
An important component of the SOG and SOGII is activated carbon.
This consists predominantly of carbon (usually >90%) with a highly porous structure. The pores are interconnected, much like a sponge (open-pored).
Activated carbon is used as an adsorbent in a range of fields, including chemistry, medicine, water and wastewater treatment, and ventilation and air-conditioning technology.
SOG + SOGII filters offer compelling advantages
Long service life (1 year)
Complete neutralisation of odours thanks to seamless construction
No generation of carbon dust
Low weight
Compact dimensions
Please ensure the filter is changed regularly, after one year,
to ensure good air quality in front of the vehicle as well

SOG DOOR VARIANT
The fan is fitted directly to the inside of the exhaust flap. The housing with the activated carbon filter is fitted to the outside. The stylish plastic housing is available in white, light grey, dark grey and black, and can also be painted to match the vehicle’s colour.

Advantage:
The SOG for the service flap is the easiest ventilation variant to fit.

Contents of the SOG door kit:

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

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

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

The high-performance fan is situated directly beneath the roof duct and ensures sufficient negative pressure even with a pipe run of up to three metres. The gas-tight sanitary hose, available from motorhome accessory suppliers, has proven its worth as it is the easiest to install when retrofitting a roof ventilation system. The parts supplied are designed to fit a waste water pipe system available from specialist camping retailers (this also applies to SOG II).

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

Advantages
Elegant solution
Well suited for use as original equipment
No maintenance required
No modifications to the vehicle side panel

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 waste water pipework system available from specialist camping retailers.

SOG II FLOOR-MOUNTED VERSION
The SOG II compact system offers a wide range of options for venting the toilet. The unit consists of a replaceable filter cartridge into which the fan is inserted. As the fan is fitted within the filter’s seal, it is barely audible.

The SOG II offers the advantage that the filter cartridge can be positioned very flexibly in a wide variety of locations within the campervan and vented through the floor at any 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 metres away from the toilet) can be fitted both upstream of the compact unit and to the floor outlet to find a suitable location.

As the filter unit is positioned inside the vehicle, no modifications to the exterior of the vehicle are required – there is no need to match it to the exterior design.

The specific technical design of the filter housing in relation to the flow technology, as well as the resulting vast filter surface area and the composition of the activated carbon, are so efficient that the extracted, odour-laden air is completely neutralised.

Therefore, for caravans where the toilet service flap 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 disconnected and the now-open connector is sealed with the suitable cap supplied.
(Filter: 90 mm H, 110 mm Ø; filter unit with fan: 160 mm H)
