sf 6 Oil-Free Compressors - Sauer Compressors USA, Inc.

Sulfr hexafluoride Oil-Free Compressors. Sulfr hexafluoride gas is a halogen compound which has a very negative impact on the environment. The greenhouse effect for gaz sf6 is 23,900 times as large as for the same quantity of CO2. Sulfr hexafluoride gas is one of the six greenhouse gases which are prohibited from freely escaping into the atmosphere. The harmful effect on the environment makes the safe and gas-tight use of sf 6 an important issue for society as a whole.Get price
