What is the main cause of contamination in gaseous oxygen systems?

In gaseous oxygen systems, moisture is the primary concern regarding contamination. While heat, pressure changes, and chemical reactions can contribute to various system challenges, moisture specifically poses a significant risk due to its potential to interact with the oxygen and form harmful compounds or even lead to combustion in the presence of certain materials.

Moisture can introduce risks such as corrosion or the formation of ice, which can block valves and filters. This makes controlling humidity levels essential in oxygen supply systems to ensure their safety and functionality. Overall, managing moisture is crucial for maintaining the integrity and performance of gaseous oxygen systems.
