Features : Anti-Foaming, Anti-Dust

Product Details

Specifications of KN95 FFP2 (GB2626 2006):

Filter performance – (must be ≥ X% efficient) = ≥ 95%
Test agent = NaCl
Flow rate = 85 L/min
Total inward leakage (TIL)* – tested on human subjects each performing exercises = ≤ 8% leakage (arithmetic mean)
Inhalation resistance – max pressure drop = ≤ 350 Pa
Flow rate = 85 L/min
Exhalation resistance - max pressure drop = ≤ 250 Pa
Flow rate = 85 L/min
Exhalation valve leakage requirement = Depressurizatio n to 0 Pa ≥ 20 sec
Force applied = -1180 Pa
CO2 clearance requirement = ≤ 1%

Definitions - 
Filter performance – the filter is evaluated to measure the reduction in concentrations of specific aerosols in air that passes through the filter.
Test agent - the aerosol that is generated during the filter performance test.
Total inward leakage (TIL) – the amount of a specific aerosol that enters the tested respirator facepiece via both filter penetration and faceseal leakage, while a wearer performs a series of exercises in a test chamber.
Inward leakage (IL) – the amount of a specific aerosol that enters the tested respirator facepiece, while a wearer performs a normal breathing for 3 minutes in a test chamber. The test aerosol size (count median diameter) is about 0.5 micro meter.
Pressure drop – the resistance air is subjected to as it moves through a medium, such as a respirator filter.

IMPORTANT: Always read and follow respirator user instructions
