1.3.4.8 Vaporizer Manifold
The vaporizer manifold (installation type: Selectatec) is used to bear the vaporizers and provide an
airtight chamber. In the chamber, the gas mixture and anesthetic gas converge into the fresh gas and
output to the downstream ACGO assembly. Each column on the manifold is a two-position three-
way valve. When no vaporizer is installed, the columns are at the original positions and the gas
mixture is delivered to the downstream through the bypass inside the manifold. When vaporizers are
installed, the columns are bended and the gas mixture is delivered to the manifold and output to the
downstream. The following figure shows the position of the vaporizer manifold in the system.
