WA 220

Pressure Differential Switchover

The WA220 Manifold prevents downtime by automatically switching gas supply from the primary cylinder bank to the reserve cylinder bank.

All components are enclosed and protected inside a tamper-resistant case. A green light indicates the primary cylinder bank is functioning and the reserve cylinder bank is ready for service. A red light alerts the user that the unit has changed over and one or both banks are depleted (except on fuel gas units). The user resets the primary bank by turning the knob.
