The SOG Toilet Ventilation System is an ecological solution for motorhome and caravan toilets. It is 100% chemical free and 100% odorless.  Made with the traditional German engineering, this solution to a smelly problem will be an investment in quality of lifestyle.


  • Additives are no longer necessary and optimal decomposition is guaranteed by the increased flow of oxygen
  • The fast and powerful ventilator immediately removes odours by suction
  • No more smells in the vehicle
  • No further problems with the pressure of gases caused by decomposition
  • The power consumption is very low at 0.43 watts.
  • Warranty period – 2 years

The ventilator is switched on as soon as the blade valve starts to open and is switched off again when the blade valve is closed.  The fact that no smells can leave the waste holding tank is brought about as soon as the ventilator is switched on there is a suction effect in the waste holding tank which draws in fresh air through the blade valve. This down flow acts as a seal and prevents the gases and smells from rising.

The fresh air that is drawn in removes the new odors in the toilet bowl when it is being used.  The decomposition process for sewerage and toilet paper is accelerated by the increased flow of oxygen so that no additional chemicals are required.  No special toilet paper is required, in fact ordinary toilet paper is recommended for use with this system.

    Only 3 star because it is installed but as yet untested. Easy install and very good quality. Based on other reviews will most likely end up 5 star.

    This item was on backorder but didn’t take long to arrive. I’m really happy with the SOG System. The installation instructions were easy to understand and with a bit of thought the System was fitted without a problem. I reckon anyone with basic handyman skills could easily install the system. And the fan operates quietly in the background while the flap on the canister is open. All in all, very happy
