weigh sf6 Evacuation Decomposition

Exposure to an arc chemically breaks down SF 6 though most of the decomposition products tend to quickly re-form SF 6, a process termed "self-healing," Hexa - REVAC Series is simplest solutions when only SF 6 gas filling air evacuation from switchgear is required.
