system. As the filter becomes dirty, it can reduce the volume of air drawn
into the ventilator.
Check the inlet filter weekly. Replace it with a new filter when the majority of
the filter surface area has changed from a clean white to dirty brown color.
Inlet filters are not reusable.
After replacing the filter, make sure that the three hold down
screws on the Filter Cover are secure. If the screws are not
tight, ambient air may enter the FLIGHT 50 Ventilator from
around the inlet cover.
HOME CAREGIVERS: When the FLIGHT 50 Ventilator is used in
a homecare environment, the filter may become dirty more
frequently and therefore must be inspected and/or changed
more often.

Proximal Inline Filter
Figure 56 – Proximal Inline Filter
Always use a Proximal Inline Filter at the Airway Pressure
Connector to protect the internal pressure transducers
from moisture or other contaminants.
Never reverse the Proximal Inline Filter.
The Proximal Inline Filter has a very important function in the FLIGHT 50
Ventilator. Located at the Airway Pressure Connector, it protects the internal
pressure transducers from moisture or other contaminants that may be
present in the proximal airway tubing. Since there is no purge flow coming
from the FLIGHT 50 Ventilator, it is important to always use a Proximal Inline
Filter.
Check the Prox Inline Filter weekly. Discard it and replace with a new filter if
it appears to have gotten wet or come in contact with a contaminant. Inline
filters are not reusable.
