摘要

The piece (2) has a tubular passage channel provided with a medium to be cleaned, an inlet opening for sucking ambient air and a plasma producing device (8) for producing plasma. A gas-permeable connection is formed between the plasma producing device and the tubular passage channel to mix the medium to be cleaned with the ambient air.
