WARNING
● Always read cartridge labels prior
to use to be certain that you have
cartridges and/or filters that will
provide the required protection. Fil-
ters labeled for protection against
particulates only shall not be used
for gases/vapors, and cartridges la-
beled for protection against gases
and vapors only shall not be used
for particulates.
● Only use three (3) cartridges or filters
of the same type.
● Never use the PAPR without all four

ure 19). Use of the PAPR without the
blower inlet gasket could allow con-
taminants to leak into the facepiece.

WARNING MAY LEAD TO PERSON-
AL INJURY, ILLNESS, OR DEATH.
1. Verify that the rubber gaskets are in place
at the bottom of the threaded blower inlets
