The manifold MM90 STANDBY is designed to be used as a third source of supply in medical central gas systems. The manifold will deliver gas when the nominal supply system pressure falls below a set level (7 bar). This is a back up source. Together with MM90 STANDBY always use the MM90 HP unit and alarm providing all alarms according to standard (like Gas alarm). As 2nd stage it is recommended to use a stabilizer. Gas Alarm is a standard accessory.
The Gas alarm gives visual and audible indication. It surveils and the alarm sounds when the following happens:
1. Too high outlet pressure
2. Too low outlet pressure
3. Empty cylinder
MM90 STANDBY INCLUDES THE FOLLOWING COMPONENTS: MM90 STANDBY Manifold with pressure switches, Purge valves, HP filters
FOR A COMPLETE MM90 STANDBY MANIFOLD ADD:
Gas alarm
Collecting pipe set (high pressure valves, and non-return valves / high pressure components)
Cylinder retaining brackets (included in gas cylinder collecting pipe set)
High pressure hoses with safety wire
Plug for close collecting pipeline
Gas name sign
Stabilizer
