Disk Filter Replacement (Annual)
The Fresh Gas/Emergency Air Intake Disk Filter is located behind the Removable Foam Filter. This filter provides a
second level of filtration to the ambient air that is delivered to the patient. This filter must be checked periodically
and replaced when necessary. The device triggers an alarm when the combination of Removable Foam Filter and
Fresh Gas/Emergency Air Intake Disk Filter become dirty. This alarm signifies that the device is still able to deliver
the correct tidal volume but one or more of its filters need replacement. The Fresh Gas/Emergency Air Intake Disk
Filter can be visually inspected after the Fresh Gas Intake assembly is removed. If the filter appears discolored it
must be replaced.
