The air entering the tunnel is filtered by the air
conditioning system and the button mushroom compost is protected from external
influences. The system has a sports filter (sensitivity 99.9%) and a blanket
filter.
There is a specially designed centrifugal type fan.
With the exhaust outlet system, the steam and
ammonia-condensed air that emerges during the filling is thrown out. Thus, a
healthy and uninterrupted filling is possible.
