SOG + SOG II Type 3000A Dometic CT3000 / CT4000

12 V venting - the clean, odorless solution!

A specially developed small high-performance fan, which switches on automatically when the toilet slide is opened, creates a negative pressure in the waste-holding tank:

This creates a "suction" at the slider opening that draws in fresh air, as well as odors created during use, and directs it outside. The drawing in of air acts as a seal and 100% prevents all unpleasant foul gases from rising from the tank. Thus, each time the cassette is used, more air (oxygen) is drawn into the cassette. Water is also supplied each time through the flushing process. However, after the slider is automatically switched off and closed, there is permanent aeration - i.e. oxygen supply - through a pipe or hose connection that is always open to the outside, which thus promotes the further decomposition process.

SOG DOOR VARIANT
The fan is mounted directly inside on the disposal flap. The housing with activated carbon filter is mounted on the outside. The attractive plastic housing is available in white, light gray, dark gray and black and can also be painted in the color of the car.

Advantage:
SOG for the service door is the easiest to install venting option.

Filter housing available in white, light grey, dark grey and black

The filtering of the WC odors to the outside is done by a carbon filter mat, which is attached to the outside of the service flap with a filter housing.

SOG ROOF VARIANT
With a special roof duct we offer the possibility to ventilate the SOG systems via the roof. The holding tank is connected to the roof grommet via a pipe.

The high-performance fan is located directly under the roof duct and ensures sufficient negative pressure even with a line length of up to three meters. The gas-tight sanitary hose available in motorhome accessories has proven to be the easiest to install when retrofitting a roof vent. The parts supplied are matched to a waste water pipe system that is available from camping dealers (also applies to SOGII)

The roof vent is maintenance-free, as no filter is required
Retrofitting is sometimes quite complex, which is why it is mainly used by manufacturers as original equipment.

Advantages
elegant solution
well applicable in original equipment
no maintenance necessary
no modification to the vehicle wall

SOGII FLOOR VARIANT
The SOGII compact unit offers a variety of options for venting the toilet. The unit consists of a replaceable filter cartridge into which the fan is inserted. The fan is barely audible due to its placement in the seal of the filter.

The SOGII offers the advantage that the filter cartridge can be placed very variably at the most different places in the camping vehicle and is vented at any place over the ground (e.g. in the garage, under the seat bench, in the double bottom or in the storage compartment).Both before the compact unit, and to the ground outlet a hose, or pipe extension (up to three meters from the toilet) can be attached around a suitable place to find.

Since the filter unit is placed inside the vehicle, there is no longer any need to modify the exterior of the vehicle - there is no need to match the exterior design.

The specific technical design of the filter housing in relation to the flow technology, as well as the resulting huge filter surface and the composition of the activated carbon, work so efficiently that the extracted odorous air is completely neutralized.

Therefore, it is recommended to install the SOGII floor variant without hesitation in caravans where the service flap of the toilet opens directly into the awning. The cassette emptying is just as simple as before: The exhaust hose is pulled off and the now open connecting piece is closed with the suitable, provided catch.

The filtering of the toilet odors to the outside happens via a filter cartridge which can be placed very variably, up to three meters away from the cassette, in the most different places in the camping vehicle (e.g. in the garage, under the seat, in the double floor or in the storage compartment). Ventilation is via the floor.
