A unique vacuum loader and process is provided to efficiently remove, effectively collect, and safely dispose asbestos, hazardous material, and other particulate matter under continuous negative pressure during all phases of operation while preventing emissions of asbestos and other particulates to the atmosphere. In the preferred embodiment, the vacuum loader comprises a four stage, dual unit, machine with a trailerable separation and filtration unit to centrifugal separate, dedust, and filter dust laden fluid and a portable bagger unit to safely discharge the removed asbestos or other material into bags or other containers.

A vacuum loader for removing asbestos hazardous material, and other particulate matter, comprising: first separator means for partially dedusting and separating a substantial amount of particulates from a dusty fluid; second separator means positioned downstream of and communicating with said first separator means for further dedusting and substantially removing the remaining particulates from said partially dedusted fluid; first conduit means connected to and communicating with said first and second separator means for passing said partially dedusted fluid from said fluid separator means to said second separator means; reinjection means located between and communicating with said first and second separator means, said reinjection means comprising a collection chamber positioned downstream of said second separator means for collecting particulates removed by said second separator means; inlet conduit means comprising an influent vacuuming hose connected directly to and communicating with said collection chamber for vacuuming a dusty fluid containing particulates of asbestos or other material under a substantially continuous negative pressure and for passing said dusty fluid containing said particulates to said collection chamber; and second conduit means positioned downstream of said second separator means and connected to and communicating with said first separator means and said collection chamber for feeding and recycling said collected particulates and said dusty fluid from said collection chamber to said first separator means; and said reinjection means comprising substantially continuous air lock means for regulating ingress of said particulates into said collection chamber and for regulating egress of said dusty fluid and said particulates into said recycle hose.
