초록

A device is described for separating airborne particles into classes depending on grain size. The principle characteristic of the present invention lies in the fact that it comprises: a hollow base body, in which, in use, a depression is created; an upper body in which is formed a channel to which there is conveyed, in use, the particle-bearing air and which has a lower extremity with a circular outline; a mesh positioned between the said base body and the said upper body and on which is positioned a filter defining, with the lower face of the said upper...
