3M™ Aura™ Particulate Respirators
9300+ Series
Technical Data Sheet
Description
The 3M™ Aura™ Particulate Respirators 9300+ Series
meet the requirements of European Standard EN 149:2001
+ A1:2009, filtering facepiece respirators for use against
particles. They provide effective respiratory protection for
use in industries where workers will be exposed to solid (dust)
particles and/or non-volatile liquid particles.
Applications
These respirators are suitable for use in concentrations of
solid (dust) particles and/or non-volatile liquid particles up to
the following limits:

*Many countries apply Assigned Protection Factors (APFs) which reduce the
maximum concentrations of particles in which these products can be used. See
national regulations and EN 529:2005.
Respiratory protection is only effective if it is correctly
selected, fitted and worn throughout the time when the
wearer is exposed to hazards.
Standards
Products are classified by filtering efficiency and maximum
total inward leakage performance (FFP1, FFP2 and FFP3),
also by usability and clogging resistance.
Performance tests in this standard include filter penetration;
extended exposure (loading) test; flammability; breathing
resistance and total inward leakage. Reusable products are
also subjected to cleaning, storage and mandatory clogging
resistance tests (clogging is optional for non reusable
products). A full copy of EN 149:2001+A1:2009 can be
purchased from your national standards body.
Filter penetration
The filter penetration, initial and after 120mg of loading with
both 120mg of NaCl* and Paraffin Oil, shall not exceed the
following limits:

*Loading of NaCl may be stopped if filter penetration during loading is
observed to decrease.
Total Inward Leakage
Ten subjects perform five test exercises whilst wearing the
respirator. The total inward leakage inside of the respirator
due to face seal leakage, filter penetration and valve leakage
is measured for each subject exercise. The subject mean total
inward leakage for 8 out of 10 subjects shall not exceed the
following limits:
