Abstract

An in-line vacuum filter comprises a manifold having an inlet, an outlet, a collecting container, and an actuatable filter paddle. A flow of air generated by a source of negative pressure travels from the inlet to the outlet. The actuatable filter paddle is positioned within the manifold such that it can be actuated between a first position and a second position. In the first position, the actuatable filter paddle is placed within the flow of air and in the second position, the actuatable filter paddle is removed from the flow of air. The filter paddle is preferably arcuate concave and comprises a plurality of apertures. In the first position, the filter paddle gradually diverts objects larger than a width of the apertures away from the flow of air. Diverted objects may travel to a removable collection container.
