摘要

The device has a primary conduit (3), in which a flow of air (4) is created, this flow of air created by a fan (5). There is a secondary conduit (15) by the intermediary of which the dust (19) is evacuated. It has an dust ejection member (12,13) disposed in the secondary circuit, and a drive member (10,11) for the ejection member which is driven by the flow of air of the primary circuit. The dust ejection member has a secondary fan (12) disposed in the body (13) having aeraulic characteristics created by the flow of air.
