Vacuum cleaner for removing toxic dust

摘要

A vacuum cleaner has a disposal unit for toxic or cancer-generating dusts which are trapped in a dustbag(5). The bag is airtight and dust- impermeable. One side has an inlet(12) which can be closed off and the other side is joined in airtight fashion with a category K1 filter element(8). Downstream of the first filter element is a second one which is directly attached at the flange to the container. The first filter element has a sealing flange (13) on its upper side, pressing tightly against the foil edge (14) of the dustbag. The element has a perforated lamination (11) on its inside. The inlet tightly seals against a fitting. Both elements are cup-shaped.
