The SEA prefilter (221) may be used with any SEA filter. Use prefilter holder PFH-T with
threaded filtration media, and prefilter holder 20062 with clip-in filtration media.
Approval of filtration media
Use only filtration media approved for use with the respirator. (USA) Consult the NIOSH
approval label supplied with the respirator and filtration media. (Europe and Australasia)
Consult the user instructions provided with the filtration media.
Note
(USA): SE400 respirators with half facepieces do not provide CN/CS protection.
Warning
Only original SEA filtration media, approved for use with the SE400, may be used.
Chemical cartridges (gas filters) must never be used without HE filters (particle filters)
fitted.
Follow established canister change-out schedules to ensure canisters are replaced
before breakthrough occurs.
Incorrect fitment of filtration media may result in lost or reduced protection of the
SE400
The SE400 should be fitted only with matching filtration media
– each filter should have the
same part number and age.
To fit threaded filtration media:
Note
: Method for SE400AT-2 is shown. For SE46 use the same method but with three
filtration media.
1.
Check that the filtration media are of the correct type and class (if unsure, check with
supervisor)
2.
Check that the model number on the filtration media is correct and that the use-by
date has not expired
3.
When using new filtration media, check that the sealed packaging is intact and
airtight
4.
Remove the filtration media from the packaging
5.
Check the filtration media for damage. Filtration media with visible physical damage
should be discarded immediately
6.
Check that the threads on the filtration media and fan unit are clean and the gaskets in
the fan unit are clean, undamaged and properly seated
7.
Screw each of the filtration media (1) into the fan unit and tighten firmly. Spin the
filter until it begins to tighten, then turn another 120º or so (slightly more than a
quarter turn). Take care not to overtighten. Note that the fan unit gasket has a self-
locking design, so the turning resistance will increase steadily as it is tightened
8.
Fit prefilters (2) into prefilter holders (3) and snap them on to inlet of filtration media.
