Abstract: An improved industrial vacuum loader is equipped with a special filter door system to permit insertion, removal, inspection, and maintenance of filters during maintenance and to safely close and lock the filters during operation of the industrial vacuum loader. The industrial vacuum loader can have a solids-gas separation compartment with a tangential cyclone separator which is preferably positioned generally alongside and laterally offset from one or more filtering compartments to minimize turbulence and re-entrainment of the collected particulate material.

Abstract: A specially arranged vacuum loader and industrial dust collector with a perforated plate tangential cyclone separator is provided to efficiently remove, readily collect, effectively separate and safely dispose of wet, dry and fibrous materials, including liquids and slurries. The special vacuum loader and industrial dust collector has a solids-gas separation compartment comprising a tangential cyclone separator, preferably a perforated plate tangential separator, which is positioned generally alongside and laterally offset from one or more filtering compartments to minimize turbulence and re-entrainment of the collected particulate material.
