SG 940 
Stainless Steel

Pressure Differential Switchover

The SG 940 Series Manifolds are designed and manufactured for high-purity gas delivery applications requiring uninterrupted gas flow and greater cylinder capacities. User friendly and easy to operate, a simple rotation of the control knob resets the unit following the system’s automatic changeover.

Factory-set functional components are protected inside a tamper-resistant case. A self-contained alarm system clearly indicates the system status. A green light shows the service bank is functioning and the reserve bank is ready for service. A red light alerts the user that the unit has changed over and one or both banks are depleted. Dry contacts in the unit’s power supply box allow connection to remote alarm systems.
