Gas manifolds

Gas manifolds are designed to supply the pipeline system with sufficient quantity of gas by cylinders and/or tanks. The typical manifold for medical gases (oxygen, nitrogen, CO2 or medical air) according to EN ISO 7396-1 or HTM 02-01 usually consists of a two-sided cylinder supply with automatic changeover between the empty and full side, and an additional third source for emergency supply. For oxygen, the liquid source is usually used as the primary supply, while the two-side cylinder supply is used for reserve.
