Warning
Regularly check the cleanliness of the air inlet filter located on the rear of the ventilator. If
necessary, replace the filter before the recommended replacement period is over (see chapter
8,
“Routine Maintenance” ). This is particularly important when the ventilator is installed on a
wheelchair, because environmental conditions may cause the filter to become dirty more
rapidly.
The ventilator features two filter types:
•
air inlet filter
•
bacteria filter
Air Inlet Filter
Consisting of foam and fine particle filter media and located at the rear of the ventilator, this filters the air as it
enters the ventilator.
Figure 4-11. Air Inlet Filter
Warning
The air inlet filter is not reusable; do not attempt to wash, clean, or reuse it.
Failing to replace a dirty air inlet filter, or operating the ventilator without a filter, may cause
serious damage to the ventilator.
Bacteria Filter
It is highly recommended that you install a bacteria filter (see Figure 4-12 ) on both single and double limb cir-
cuits. In a double limb configuration, two bacteria filters are used: one at the
TO PATIENT port, and the other at the FROM PATIENT port.
•
Connected to the TO PATIENT port:
This filter protects the ventilator from contamination by the patient (primarily, rebreathed gas).
