ABSTRACT:
A special bagger unit is provided to remove and contain asbestos, hazardous material, and other particulate matter in an efficient, effective and safe manner. The special bagger unit operates under continuous negative pressure for all phases of operation while preventing emissions of asbestos and other particulates to the atmosphere. Desirably, the special bagger unit has a vacuum operated assembly with a filling member which communicates with an inlet port and a separate fluid outlet port. In the preferred embodiment, the filling member comprises a tubular vacuum cylinder which discharges asbestos and other particulate matter downwardly into a container, such as one or more sealed bags which can be placed in a drum or other vessel. The container is preferably supported and partially sealed by a support platform, such as a moveable platen, supported on a base. The vacuum operated assembly can have a bulk separation chamber with a cyclone and a deflector, such as a conical baffle or other baffles, to minimize backflow of the removed asbestos and particulate material.
