Chapter 7. Air Supply
There are two sources of air supply to the Companion 2 Driver: external air and
internal compressors.
The primary source of air supply to the Companion 2 Driver is external air.
Whenever available, the Driver must be connected to external air
( Figure 7-1 ).
In times of patient transport, the compressors may be used, but the Driver should
be reconnected to external air when available.
It is recommended that the external air pressure for the Companion 2 Driver be
between 50 to 80 PSI (3.5 to 5.5 Bar). If the external air pressure is below this
range, it will not impact the Driver functionality; however, it may result in a
System Malfunction Alarm. If a System Malfunction Alarm is displayed while on
external air, remove the external air connection from the Driver and verify that the
alarm clears. If the external air pressure is above the specified range it will not
impact the Driver functionality, however, the internal compressor may activate
intermittently. When the compressor activates, the external air icon on the display
will not be illuminated.
