The MM90 HP unit medical manifold is intended for use in hospital pipeline system as medical gas source. Together with MM90, always use an alarm providing all alarms according to standard (like gas alarm C44). As 2nd stage is recommended to use a stabilizer. The manifold will deliver gas from the operating bank to the manifold pressure regulator until the cylinders are exhausted. At that point the supply will switch to the reserve bank and the exhausted bank can be replenished. The object gives uninterrupted gas supply.
