Abstract (en)
[origin: EP0667311A1] The device has a connection (23) for coupling to a pneumatic delivery conduit together with at least one filter component on its upper side. The filter component is a one-part filter bag (3) upwardly inflatable balloon fashion, the lower inflow aperture of which, when viewed in a horizontal plane, corresponds to the free cross-section of the basic body. Between the inflow aperture of the filter bag and the opening of the storage funnel (2) a grid (5) is arranged. The storage funnel has a paddle-type filled position indicator (11), which is arranged pref. on one wall of the funnel. The filter bag in its horizontal opening cross-section corresponds to that of the free opening of the basic body.
