  • Patent number: 7323022
    Abstract: The subject invention pertains to a vacuuming machine with a primary chamber in which vacuum pressure within allows the ingress of debris through a hose. Air and debris entering the primary chamber decelerate upon entry into the chamber which allows debris to settle out of the air column within the primary chamber. Air within the primary chamber is evacuated through an enlarged filter and duct system that carries the air through a filter hopper and fan plate to a rotating fan. The blades of the fan move air and particulate matter through a second duct into a secondary chamber in which another deceleration of air and debris allows additional debris to settle to the bottom of the secondary chamber before air is finally evacuated from the vacuum machine.
