What is the PSI of the High Pressure Cylinders used to deploy an Airbag?

• A. 4000+ psi
• B. 2000 psi
• C. 800 psi
• D. 6000 psi

Answer: (B)

Airbag deployment relies on stored compressed gas in high‑pressure cylinders to provide a rapid, controlled inflation. The standard cylinder pressure is about two thousand pounds per square inch. This level supplies enough gas quickly to fill the airbag in milliseconds, creating the protective cushion without requiring equipment capable of handling much higher pressures. Pressures around four thousand or six thousand psi would necessitate heavier, more robust hardware and aren’t typical for airbag inflators, while a much lower pressure (like eight hundred psi) wouldn’t deliver sufficient gas for fast inflation. So, the usual value is around 2,000 psi.
