MM90 Standby Gas Manifold

Manifolds and stabilizers

The GCE MM90 Standby gas manifold is designed to be used as a third source of supply in medical central gas systems.

MM90 Standby Gas ManifoldIntroduction

The GCE MM90 Standby manifold delivers gas when the nominal supply system pressure drops below 7 bar, serving as a backup source. The MM90 Standby should always be paired with the MM90 HP Unit and an alarm system to comply with standard requirements. It is recommended to use a stabilizer as the second stage.

The GCE Gas Alarm offers both visual and audible alerts, monitoring and signaling when the outlet pressure is too high, too low, or when a cylinder is empty, ensuring continuous safety and operation.

MM90 Standby Gas ManifoldFeatures

MM90 Standby includes the following components:

MM90 Standby backup gas manifold with pressure switches, purge valves, and HP filters
