The Vacuum Attachment is part of an integrated system designed to collect Lithium (Li) Power for storage in mineral oil or to passivate it in Vinegar or Chilled Water. Major components are: Mister, Li Trap, Oil Trap or Combustion Chamber and Ash rated Shop Vacuum. The Mister provides a fine coating of mineral oil, vinegar or water to the lithium powder reducing the possibility of non passivated particles causing an exothermic reaction before entering the Li Trap. The Li Trap has a vacuum port located above the oil, vinegar or ice water level while the inlet extends down below the liquid's surface. The Oil Trap collects oil and or Li powder before reaching the Ash Vacuum. The Combustion Chamber has a continuous ignition source such as a spark plug or hot wire to burn off any volatile passivation byproducts before reaching the Ash Vacuum.
