SF Maintenance Equipment Fundamentals

The main component in any gas recovery system is the compressor. It is used to transfer SF 6 from the GIE to the storage tank. Depending on design, it may also be used to transfer gas from the storage tank back to the GIE. There are several compressor designs that are currently used: oil-based, oil-free, and oil-less.Get price

C3F8 Superior to sf6 gas and Air in Treatment of Vitreomacular

“You can use Sf6, which lasts about 2 weeks and expands twice, or you can use C3F8, which expands about 3 or 4 times, but only lasts about 2 to 2.5 months in the eye, so there are certainly different choices.” In the clinical trial,C3F8 had superior release rates versus Sulfr hexafluoride or air (p<0.05).Get price
