Did you buy the right Mask BFE Tester?

Mask BFE Tester adopts dual gas path simultaneous comparison sampling method, which improves the accuracy of sampling, and is used to test the bacterial filtration efficiency of disposable medical masks, medical surgical masks, civilian masks and other daily protective masks and meltblown cloth for production masks. It is suitable for performance testing of the bacterial filtration efficiency of masks by metrology and verification departments, scientific research institutes, mask manufacturers and other related departments.

Features of Mask BFE Tester:

1. Negative pressure experiment system ensures the safety of operators.

2. The negative pressure cabinet has a built-in peristaltic pump, A and B two-way six-stage Andersen.

3. The flow rate of the peristaltic pump can be set.

4. The spray flow rate of the microbial aerosol generator can be set.

5. Embedded high-speed industrial microcomputer control.

6. 10.4-inch industrial-grade high-brightness color touch screen.

Filtration efficiency is generally divided into three types, for example:

(1) BFE refers to bacterial filtration efficiency (Bacterial Filtration Efficiency), which targets particles with a size of 3 microns, which can block pollen and droplets;

(2) PFE stands for Particle Filtration Efficiency (Particle Filtration Efficiency), which targets particles with a size of 0.1 microns, which can block viruses such as influenza and SARS;

(3) FE stands for Virus Filtration Efficiency, for particle size of 0.1 to 5 microns.
