  • the filter device can be blown free as far as possible with a short blast of air.
  • an advantageous compression device and an advantageous method for compressing bulk goods in open containers are made available, with a larger one Cleanliness of the facility is achieved. At the same time, faster filling and compacting can also take place, with the energy consumption also being able to be reduced.
