ABSTRACT:
For the removal of dust, various types of jets are used, mostly as attachments to household and industrial suction tools.
In order to achieve a contactless and, therefore, protective cleaning, the attachable blow and suction jet according to this invention is configurated in such a way that a turbine wheel (7) positioned in a suction pipe (1) is driven by means of a suction tool and then moves a second turbine wheel (8) in a pressure pipe (5) via a shaft (9) thus generating compressed air. The compressed air is conducted to a blow pipe (31) via connecting pipes (24). With the use of an additional cap (26) the exhaust air can whirl with the intake air in some distance from the mouth of blow pipe (31) and be carried off between the connecting pipes (24) via the suction pipe (1) into the suction tool.
