1.
Air inlet (the air has the same
temperature as the room
where it is installed).
2.
Air is preheated by a heater
(when installed and ON) when
transported between the
cylinder and hood if the
temperature is below 10-16ºC.
3.
Air inlet into the cylinder.
4.
Fan extracts the hot moist air
from the cylinder.
5.
Air outlet from the cylinder
6.
Ventilation filter.
If the airflow is too strong the compost material will dry out, if it is too
low the compost material will be too wet and/or bad odour may leak
out from the composter. The setting of the fan is dependent on the
ventilation of the installation area. The fan speed changes immediately
when the value is changed. In some installations the fan should be still
during the wait time, however this is very rare.
There is more information about ventilation and airflow in the
installation manual.
The oxygen supply to the material is regulated by the fan but more
importantly by the number of rotations and wait time functions see
below.
Note! Without the fan functioning properly and ventilation being kept clean the biological process
will not work!
