Detailed Product Description
Pressuring Of Cabinet: (-50 ~ -200) Pa Power Consumption: < 1500 W
Working Power: AC 220 V ± 10%, 50 Hz Host Size: 1180 * 650 * 1300 Mm (L X W X H)
Bracket Size: 1180 * 650 * 600 Mm (L X W X H), Height Adjustable Within 100 Mm


Masks Bacterial Filtration Efficiency Tester is used to determine the bacterial filtration efficiency (BFE) of medical face masks, surgical face masks, to identify the protective performance from being exposed to bacterial airborne environments, tester can conduct the tests defined in EN14683, ASTM F2100, ASTM F2101, GB 19083, YY 0469.


The bacterial suspension is pumped to the nebulizer, the aerosol will be pushed into the aerosol chamber then delivered into two sets of (Anderson) sieve samplers, one with testing specimen, another without specimen in order to compare the different results.


Designed with two sets of Anderson sieve samplers it is possible to get the results with and without testing specimen at the same time, reduce the bias to the minimum, and the machine has a embed clear 3-level (disinfection liquid, purified water, airflow) cleaning system to ensure the safety after the tests.
