To provide information on how SF6 gas filtration works and what are the processes required to ensure safety, quality, and consistency when filtering SF6 gas of contaminants. The major contaminants are, moisture, decomposition products, other vapors, and oil. These major contaminants must be removed from SF6 gas exposed to those contaminants to ensure its condition meets the specifications for re-use in SF6 Gas Insulated Equipment (GIE). This paper provides further guidance on the resources required to perform proper SF6 gas filtration for reuse, including a recommendation of tools needed, how these tools must be maintained to ensure the objective of the scope is met. Further the paper provides guidance on the proper use of the tools and the training any maintenance team must have to guarantee the health and safety of the team, the tools and equipment and just as important the environment.
