Abstract (en)
The bag has an admission opening surrounded by a retaining plate, which is fixed on an air permeable non-woven fabric (4). The fabric filters air stream and is multi-layered. An airtight foil (5) is tightly fused with the fabric, is transparent and enables a fill level control. The foil is provided in the inner side of the filter bag with an antibacterial coating. A ring made up of non-woven material forms a sealing for a nozzle that is inserted into the opening.
