OverviewDual-circuit secondary pressure-reducing box for oxygen distribution. When one circuit is unavailable, the system switches to the standby circuit to maintain continuous gas supply without pressure interruption, complying with the 'continuous gas supply under a single fault' requirement of GB 50751-2013. Testing report available per GB 50751-2012.
