What is a SOG Ventilation System

  “When nature calls….”

Opening of the toilet valve activates a low powered extraction fan, 0.43 watts.  This creates a mild vacuum or negative pressure within the cassette which draws oxygen into the cassette from the bathroom area.  This action seals off odours contained in the cassette and draws into the cassette personnel odours during use.

The fan only operates when the toilet is in use.

Driving smell no longer exists.  All toilet cassettes are placed in “release mode” when the cassette is in position.  This results in ammonia and methane odours/pressure circulating in the interior of the vehicle if sealing of the toilet chamber is not 100%, which is close to impossible.

SOG systems provide a sealed pipe path, for odour/pressure to passively release, via a charcoal filter, to the outside of the motorhome.

The underlying principle of  SOG ventilation systems is the passing of oxygen over the surface of the waste, whether this is accelerated when the fan is in use or passively as pressure escapes from the cassette via the SOG piping system to the outside of your vehicle.  This is the natural curing “oxidisation” process used by all District Councils to treat waste discharge.

Naturally treated waste has far less smell when emptying the cassette and you can use normal toilet paper.
