4.3 Nylon Mesh Inlet
Filter
A dirty nylon mesh inlet filter can cause high operating temperatures and
affect ventilator performance. A damaged mesh filter can allow lint and dust
from a damaged or missing air inlet filter element into the ventilator, which
can contaminate the internal air pathways. Examine the filter for cleanliness
and damage before each use and as required during operation. Replace the
nylon mesh inlet filter (Figure 4-2) as required.
The nylon mesh inlet filter can be cleaned and reused or replaced, depending
on its condition. See Chapter 5 for component removal/installation instructions.
•
inspect the filter housing nylon mesh filter for lint, dust, or damage.
Use a vacuum (
not
a compressed air source) to remove lint or dust.
•
If cleaning the filter
: use a solution of mild soap and water to clean,
then rinse thoroughly. Ensure that the filter is completely dry before
reinstalling.
•
If replacing the filter:
remove the paper backing from the new nylon
mesh inlet filter. Align the new, clean filter with its filter enclosure,
then press the edges firmly in place to ensure adhesive bond.
•
When cleaning the nylon mesh inlet filter, use care not to damage the
adhesive on the edges of the filter. If the adhesive is damaged, the
filter may not seal correctly when reinstalled.
•
Use only Respironics-approved parts.
