The auto change-over medical gas manifold is a compact supply system for installations requiring uninterrupted low to medium flow capacities, typically 1 – 4 theatres with simultaneous flow.

The manifold consists of two banks of cylinders, one on each side of the pressure control assembly. The position of the lever determines which bank of cylinders is “in use” and which is “in reserve”. The manifold draws gas from the “in use” cylinder bank until it is emptied.

The manifold then automatically starts drawing gas from the “in reserve” cylinder bank. When the emptied cylinder bank has been replaced the level should be moved to the other side to reset the manifold.
