摘要

Before induction, spray electrode (2) technique is applied which in front of the opening (1) accelerates away outwards all toxic material (4) from air. Thus air which goes into channel is made available as absolutely clean and healthy in the breathing range of the human being by this spray electrode effect beforehand. The current supply of the spray electrode technique is, or can be, switched off and on according to air dampness or air quality or rain.
