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