KINGFA FFP2 NR D particle filter half mask, dolomite dust tested according to EN 149:2001 + A1:2009
Kingfa FFP2 NR D masks have a very good fit and can be worn comfortably for a long time. The nose section is padded with a foam and thus has a very comfortable fit. The masks are individually packaged and available in navy blue, white and green.
Dolomite dust tested
The EN 149 test (dolomite dust test) is a voluntary test and subjects the mask to an absolute endurance test.
In occupational safety, this test is even a basic requirement and the mask is given the D mark after passing it.
For use in the medical field for infection protection, this test means increased safety, since the KINGFA FFP2 masks have an increased filtering capacity and a very high absorption capacity.
Technical details:
Particle filtration efficiency (PFE) ≥ 94%.
Breathing resistance (inhalation, 30 L/min): ≤ 0.7mbar
Breathing resistance (inhalation, 95 L/min) : ≤ 2.4mbar
Breathing resistance (exhalation, 1600 L/min): ≤ 3.0mbar
Total Inward Leakage (TIL) : For particle filtering half masks as specified by the manufacturer, at least 46 of the 50 individual exercise results for total inward leakage shall not be greater than 11% for FFP2, and in addition, at least 8 of the 10 individual wearer arithmetic averages for total inward leakage shall not be greater than 8% for FFP2.
Flammability: ≤ 5S
Dead space: ≤ 1.0%
