A modern well-functioning dry toilet is odourless and pleasant to use. A well-functioning dry toilet requires that certain basic rules have been observed when building, installing and selecting appliances.
According to the basic principle of air exchange in the dry toilet, a large amount of air flows from the room space through the toilet seat and ventilation pipe to the roof. It pays to lead the replacement air to the lower part of the toilet room, for example, by leaving a narrow chink under the door.
A straight ventilation pipe is conducted from the toilet tank to the roof. Seal the pipe using a suitable lead-through sealing on the ceiling. Avoid making curves in the ventilation pipes, as any curves will hamper the free flow of air. If you must make curves in the ventilation pipe, we recommend not making more than 2 of them and with a gradient of less than 45 degrees.
If you have had to make some curves in the ventilation pipe, you can boost the circulation of air using a ventilator, as necessary.
If you install the toilet indoors, it is well worth improving the ventilation using a separate ventilator. Otherwise, fireplaces and stove extract fans can divert airflow from the toilet in the wrong direction towards the living space. In apartments with mechanical ventilation, it pays to combine ventilation of the toilet with the mechanical ventilation.
You can install a ventilator with electric drive to assist ventilation in the dry toilet. The ventilator is installed in the ventilation pipe inside the toilet.
Biolan Exhaust Ventilator is suitable for toilets:
Optionally, the ventilation of the toilet can be improved by installing a Wind Ventilator in the end of the air pipe on the roof. The Wind Ventilator fits directly onto a 75 mm or 110 mm pipe.
