DRK-666 Blocking Test Sample Processor

The blockage test sample processor is used for the EN149 standard respiratory protection device-filter type anti-particulate half mask. European standard mask dolomite dust clogging test machine dolomite test, the English name is Optional Dolomite Clogging Test, which is one of the test masks in the European CE standard, for three filtering levels, FFP1 (minimum filtering effect ≥80%), FFP2( The lowest filtering effect≥94%), FFP3 (the lowest filtering effect≥99%).

Applications:
Used for EN149 standard respiratory protection device-filter type anti-particulate half mask
The blocking test sample processor complies with the standard:
BS EN149-2001 Respiratory protection device-filtered anti-particulate half-mask requirements, testing, marking 8.10 obstruction test and other standards.
