Bacterial Filtration Efficiency Tester
Surgical Mask Tester Bacterial Filtration Efficiency (BFE) Detector is mainly applicable to the measurement and verification departments, scientific research institutes, medical mask manufacturers and relevant testing departments for the performance of mask bacterial filtration efficiency.
Bacterial Filtration Efficiency Tester is applied to test the filtration efficiency of mask, can be used in metering calibration department, scientific research institution, mask manufacturer and other related departments.
BFE Tester Standards:
YY 0469-2004 Technical requirements for surgical mask
BS EN 14683-2014 Medical face masks - Requirements and test methods
ASTM F2100-2019 Standard Specification for Performance of Materials Used in Medical Face Masks
ASTM F2101 Standard Test Method for Evaluating the Bacterial Filtration Efficiency (BFE) of Medical Face Mask Materials, Using a Biological Aerosol of Staphylococcus aureus
Mask Bacterial Filtration Efficiency Tester Feature:
1.Switching type glass door in front of the machine, easy to observe by the operator.
2.Peristaltic pump was built in the negative pressure cabinet, A & B two routes 6 level Andersen sampling head.
3.The flow speed of peristaltic pump can be set.BFE tester good atomization effect.
4.Bacterial Filtration Efficiency Tester Of Mask: Negative pressure testing system, which can protect operator’s safety.
5.The spray flow of bacterial liquid inside the special microbial aerosol generator can be set.
6.10.4 "industrial high brightness color touch screen display.Embedded high speed industrial microcomputer control.
