SOG Toilet Ventilation System - Door Vent

The SOG Toilet Ventilation System is an ecological solution for motorhome and caravan toilets. 100% chemical free and 100% odourless. There is no need for the use of chemical additives since the air extraction system naturally breaks down waste in a completely environmentally friendly way through the addition of Charcoal.

This system is available for all popular 12V Thetford and Dometic cassette toilets, as well as for permanent black water tanks. Choose from standard door, roof or floor venting models, all designed to match your existing cassette toilet.

This door vent model has the fan installed directly on the inside of the disposal flap. The housing with the activated charcoal filter is mounted on the outside. The external filter housing cover is available in white, dark grey & black which can also be painted in the same colour as the vehicle.

Features:

• 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
• The door model is the easiest ventilation system to mount

Includes: 

• Fan – the heart of the system
  
• Adapter parts
  
• Cable set with switch to supply
• Power to the fan
• Filter housing
• Activated charcoal filter mat
  
• Complete set of small parts for installation
• Installation instructions

1. The ventilator is activated automatically when the toilet valve is opened, creating pressure in the water-tank stopping any odors from being released. 
2. This creates “suction” at the valve opening, drawing in fresh air through the valve. Odours arising during use are therefore drawn in with the air and directed outside. 
   This downflow acts as a seal and prevents the gases and smells from rising .This means more air (oxygen) is sucked into the cassette with each use. The flushing process also adds water each time.
3. The ventilation system will then turn off with the closing of the toilet valve but continues to provide permanent aeration – as the oxygen supply – through a pipe or hose connection that is always open to the outside, decomposition process
4. The decomposition process for waste and toilet paper is accelerated by the increased flow of oxygen so that no additional chemicals are required.

Use & Care:

• The waste tank should be thoroughly rinsed with clear water and shaken after emptying to avoid deposits. The cassette should then be filled with half a litre of water.
• Always use normal toilet paper, NOT recycled paper, because special paper does no decompose as well as ordinary, lower-priced toilet paper when oxygen is used.

Door/Side Wall Vent SOG models have a minimum mounting depth of 30mm (pack is required if your service door is thinner - recommend 70mm diameter ply with 38mm hole within it)

• For the SOG Type 320S (floor variant):

  • Filter (activated carbon) dimensions: 90 mm high × Ø 110 mm

  • Filter unit with fan: 160 mm high

  • Supplied hose length: 65 cm, but SOG allows extension up to 3 m (with gas-tight/exhaust hose) 

• For the SOG “Ecological System” for Dometic CT3000 / CT4000:

  • Product dimensions: ~8.9 cm × 22.5 cm × 18.6 cm (L × W × H)

  • Weight: ~520 g 

• For the SOG Type F (Thetford C250 / C260):

  • Dimensions: 22.8 × 22.2 × 8.4 cm (L × W × H) per the user manual.

  • Another spec sheet lists 22.5 × 8 × 19 cm for a similar model. 

• For SOG Type H (Thetford C223 / C224):

  • Shipping / packing dimensions: 19 cm × 23 cm × 9 cm 

  • Operating voltage: 12 V, power draw ~0.43 W.

• For door-vent / wall models:

  • The wall vent (door) has a minimum mounting depth of 30 mm. If your service door is thinner, you'll need a “packer” to build it up.
