<p>A dust collector includes two tubes (6, 7) which communicate through an interconnecting conduit (11). A first tube (6) operates as a cyclone which separate a great fraction of dust or solid components from the incoming air and collects the same in a bag (19) at the bottom of the tube. The second tube (7) includes a filter unit (24) composed of a coarser filter as well as a surrounding fine filter, said filter unit receiving the pre-purified air from the cyclone tube through the interconnecting conduit and separating the remaining dust particles therefrom. </p> |
