 Aura

 Particulate Respirators 9300+Gen3 

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:

EN 149:2001+A1:2009

*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:
