Sulfur hexafluoride - Wikipedia

Like xenon, sulfur hexafluoride is a nontoxic gas, but by displacing oxygen in the lungs, it also carries the risk of asphyxia if too much is inhaled. Since it is more dense than air, a substantial quantity of gas, when released, will settle in low-lying areas and present a significant risk of asphyxiation if the area is entered.Get price

O2 - oxygen compressor: HAUG Sauer Kompressoren AG

Oxygen is generated using a PSA-, VPSA- or membrane system. Depending on the process, the pressure from the generation plant is either at atmospheric pressure (VPSA) or at around 4 bar (PSA). Depending on the application for which the oxygen is being used, the pressure may then need to be increased. This is achieved using a booster.Get price
