- Working Stress: 11 inches WC
- Lockup Stress: 14 inches WC
The primary-stage system regulator reduces the container stress to roughly 10 kilos per sq. inch (PSI). The second stage system regulator additional reduces the stress from 10 PSI to 11 inches WC, which is roughly equal to six.3 ounces per sq. inch or ½ PSI.
