摘要： PROBLEM TO BE SOLVED: To simplify movement, carry-in, and carry-out of an apparatus without enlarging a recovery device by constituting the device by a vacuum recovery pump having discharge pressure capable of evacuation and recovering inside an SF6 gas filling apparatus, and capable of expanding a telescopic recovery container, and an SF6 recovery container having a telescopic function. SOLUTION: An SF6 gas recovery device 13 is composed of a vacuum recovery pump 6, a filter harm eliminating cylinder 2, and an opening/closing valve 1. In the vacuum recovery pump 6, a scroll type and evacuation capacity is 200 little/minute, vacuum achieving degree is 1×103 Torr, and compression discharge capacity is 0.15 MpaAbs, and has a capacity which is suitable for filling to a telescopic container 14. In the telescopic containers 14, two outer layer rubber made 40 little containers for metal coating are used in parallel with each other. By rubber and resin film made telescopic container, an evacuation capacity of the recovery container is reduced to 1/50 to 1/1,000 of a metallic container. It is thus possible to easily handle this device without enlarging the recovery device of SF6.
