Controls the gas delivered to the breathing system.
The main functions are:

pressure for the fresh gas supply.
• Inspiratory fresh gas channel that measures and
regulates the fresh gas to the breathing system.
Gas modules
There are two different versions of the gas module:
• Type I recognized by the metal nozzle unit.
• Type II recognized by the plastic nozzle unit.
As from S/N 01501, Type I was replaced by Type II in
the production of KION workstation. For information
regarding compatibility between Type I and Type II,
refer to SpeedInfo 008/02 EM LSS.
If not stated otherwise, this functional description is
valid for both versions.

The G

marked BP are modified to handle

the backpressure created when supplying fresh gas
to vaporizers. Max. flow from the gas modules
modified for backpressure is reduced to 2 l/s.
The modification concerns PC boards inside the gas
module and the nozzle unit. Without these modifica-
tions, the backpressure would disable the
diaphragms closing function.

The filter housing and the filter cover is provided with
matching guide pins. These guide pins prevents

A non-return valve for the gas inlet is located in the
inlet filter cover. This valve will suppress short
pressure drops in the gas supply. The non-return
