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