At what pressure are low pressure oxygen systems usually pressurized?

Low pressure oxygen systems are typically designed to operate within a pressure range of 400 to 450 psi. This level of pressure is sufficient to ensure that the oxygen can be easily delivered to the users without the danger of excessive pressure that could lead to leaks or system failures.

The chosen pressure range is important for the safe use and functionality of the oxygen systems in aviation, where consistent and reliable oxygen supply is critical for pilot and crew safety, especially in altitude-related scenarios. By maintaining a pressure within this range, systems can effectively manage the oxygen required for physiological needs while staying within safe operating limits.

More extreme pressure ranges, such as those exceeding 600 psi or falling well below 200 psi, may not provide the same safety and efficiency in oxygen distribution. Systems that are designed to operate at significantly higher pressures (like 1800-2000 psi) would be categorized as high-pressure systems and would require different handling and design considerations compared to low-pressure systems.
