Medical Gas Supply System
4109992485.00
Modular manifold headers for gas cylinders can be
connected to the Manifold Changeover System to
congureitsgassupplycapacity.
The Manifold Changeover System is connected to the
pipelinedistributionsystemupstreamoftheemergency
supply, or downstream of the primary supply system
when used as backup. It can be isolated from the
pipeline distribution system by the lockable isolation
valvesupplied.Whenusedasabackupsupplythisvalve
should be left open during normal operation, so the
unit will automatically supply the pipeline distribution
system with medical gas in the event of the primary
systemfailingtosupply.
When used as a backup manifold system the line
