Profile
The filtration efficiency testing equipment is mainly used for the filtration efficiency testing and air flow resistance testing of masks and melt blown cloth,equipment reference standard YY0469-2011 GB2626-2019 EN1822-3:2012 GB19083-2003,GB2626-2019 (reference KN95), GB / T32610, EAST-RP-CC021.1 and other standards.
The device is composed of NaCl cargo oil medium generator, air flow meter, humidifier, seal box and corresponding pipeline.
Mask filter efficiency tester Parameter
| Air source system: Exhaust volume: 10 ± 1.00 L /m Particle size of solid aerosol: 0.075 ± 0.02um Concentration: ≤ 200mg/m3 Test flow range: 15-100L/min | |
| Test sample specification: 100 cm2 /12cm2 (PTFE / fiberglass strip), equipped with multi specification clamps (plane mask, 3D mask) Resistance test: measuring range 0-1000pa, accuracy up to 0.01pa, automatic return to "0" function Efficiency test: efficiency range 40% - 99.999%; Fog dust source: NaCl, PSL, dehs, DOP | |
| Basic principle: the aerosol generator is used to generate a certain concentration of gas, and then a photometer is used to measure the gas concentration for particle size detection before and after breathing NaCl concentration: 200mg / m3 Flow accuracy: 10-100 L/min, accuracy 2% Test medium: NaCl Pressure: 500Pa Structural composition:Particle generator, flow detection device, concentration detection device | |
PFE TEST
While BFE and VFE tests are designed to find out how well a mask filters biological aerosols, the PFE test measures how well it filters airborne particles such as pollen or dust. This is done by filtering particles about 0.1 micron in size.
The higher the PFE of a mask, the more particles it filters. If it can filter particles about 0.1 micron wide, it is likely to be able to filter droplets that are typically much larger, and which might contain SARS-CoV-2.
For example, a mask with a PFE of 95 per cent – meeting the requirements for medical and surgical masks (ASTM F2100-19 Level 1 barrier protection) – blocks 95 per cent of particles it is exposed to.
