Particulate Respirator (EN149:2001)

PARTICULATE RESPIRATOR (EN149: 2001)

FFP1 particulate respirators- Approved for use against solid and liquid aerosols according to EN149:2001. Suitable for protection againts non-toxic harmful materials in concentrations up to 4 X OEL or 4 X APF.

FFP2 particulate respirators- Approved for use against solid and liquid aerosols according to EN149:2001. Suitable for protection against low to average toxicity harmful material in concentrations up to 12 X OEL or 10 X APF

FFP3 particulate Respirators- Approved for use against solid and liquid aerosols according to EN149:2001. Suitable for protection againts high toxicity harmful materials in concentration up to 50 X OEL or 20 X APF

EN149:2001 +A1:2009
-Dolomite Clogging Test Approval
-Dolomite clogging test is an optional test under morms EN149:2001
-Those respirators which pass the dolomite clogging test are proved a more comfortable breathing while wearing the respirators and will be marked as symbol”D”after the class of respirators such as FFPID
-The Dolomite test is to expose the respirator under a concentration of dolomite dust at 400_+100 mg/m3 with dust size ranging from 0.7~12 m with a simulated breathing at 2 liter/stroke
-Continue the test until measured dust concentration and exposure time 833 mg
-h/m3 or until the peak resistance reaches the specified limit
-Then measure the breathing resistance and the filter penetration

Note:
MAC= Maximum Admissible Concentration
OEL = Occupational Exposure Limit
TLV = Threshold Limit Value
APF = Assigned Protection factor
