What type of gas is typically used to service emergency pneumatic system gas-storage bottles?

The typical gas used to service emergency pneumatic system gas-storage bottles is nitrogen. This choice is based on several important factors. Nitrogen is an inert gas, which means that it does not support combustion or react with other substances, making it a safe choice for use in emergency systems. Its inert properties also help prevent corrosion within the gas-storage bottles, ensuring longevity and reliability of the pneumatic system.

Additionally, nitrogen is readily available and cost-effective, making it a practical option for maintenance and servicing. The gas can be easily compressed and stored at high pressure, suitable for the requirements of pneumatic systems, which often operate under significant pressure conditions. Its properties align with the operational needs of emergency systems, which must be reliable and functional when needed most.

Using nitrogen for pneumatic systems also helps maintain consistent performance in varying temperatures and conditions, which is crucial for emergency operations.
