SOG makes it possible to use the toilet without having to worry about bad odours – even without sanitary additives.
How does it work?
A specially developed high-performance fan switches on automatically when the slider is opened, creating negative pressure inside the waste tank. This generates suction (German: "Sog") at the slider opening, drawing in fresh air and any odours produced during use and expelling them outside. The inward airflow acts as an air barrier, preventing unpleasant gases from rising out of the tank. Each time the toilet is used, oxygen enters the cassette, along with water from flushing. Even after the fan switches off automatically when the slider is closed, a permanently open pipe or hose connection ensures continuous ventilation. This supply of oxygen promotes the decomposition process.
Important: replacement and activated carbon filters should be changed annually.
The electric toilet ventilation system is optimised for the camping toilet C400. With three different versions – floor, roof and door – there is a suitable solution for every installation situation.
Floor version: The SOG II floor version is characterised by its versatility. The unit consists of a replaceable filter cartridge into which the fan is inserted. This can be placed up to three metres away from the toilet and vented anywhere on the floor, e.g. in the garage, under the bench seat, in the false floor or in the storage compartment. This variant is particularly recommended for caravans in which the toilet service door opens into the awning. The specially developed filter unit effectively neutralises the extracted, odorous air and ensures fresh air in the living area.
Roof version: The roof version of the SOG II enables efficient ventilation through a roof duct. A high-performance fan, which is placed directly under the roof duct, ensures sufficient negative pressure and optimum air circulation in the duct section, which can be up to three metres long. The parts supplied are matched to a standardised waste water pipe system, which is available from specialist camping retailers. This version is also maintenance-free, as no filter is required.
Door version: With the door version, the fan is mounted directly on the inside of the disposal door, while the housing with activated charcoal filter is mounted on the outside. The plastic housing, available in white, light grey, dark grey and black, can also be painted in the colour of the vehicle. This version is the easiest to install and still offers efficient odour neutralisation.
With the SOG II versions for floor, roof and door ventilation, there is an ideal solution for every installation situation, ensuring fresh air and maximum comfort when camping.
