  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non- flammable, and non-toxic.

    units. Oil-based compressors rely heavily on oil traps, scrubbers and filters to remove compressor oil from the SF 6. Arguably, some oil will remain in the gas and transfer to the GIE. Oil-free compressors contain oil in the crankcase, but provisions are made to keep the oil from seeping into the compression chamber.
