bfe test equipment

Mask Bacterial Filtration Efficiency Tester is composed of aerosol generating system, aerosol chamber and aerosol transmission device, negative pressure cabinet, 28.3L / min C sampler, etc. The entire detector is controlled by the console. The console uses a microcomputer control system to coordinate and control the work of the aerosol generation system, transmission system, negative pressure cabinet, and sampling system, and displays the working status in real time. The entire measurement work is automatically completed.

* Professional negative pressure bio-safety cabinet technology to ensure the safety of operators and the surroundings;
* High negative pressure working chamber, two-stage high efficiency filter, 100% safe discharge;
* Two - way, six-stageAnderson accurate sampling is adapted.
* Built-in peristaltic pump and the volume is adjustable.
* Special microorganism aerosol generatorwith adjustable bacteria flow and good performance of atomization.
* Separated and color touch screen control, easier to operate.
* USB interface, can reserve your test data in different forms.
* RS232/Modbus standard interface (or customized protocol)
* Built-in LED lighting for better observation during test.
* Built-in UV disinfection lamp to enhance the protection effect.

ASTM F2100 standard specification for performance of materials used in medical face masks
EN 14683 standard that medical face masks in Europe are required to comply with
ASTM F2101 standard test method for evaluating bacterial filtration efficiency (BFE) of medical mask materials using Staphylococcus aureus biological aerosol
YY0469-2011 Technical requirements for surgical mask

Portable Mask Tester is designed to test the filtration efficiency, protective effect, leakage rate, inhalation resistance, edge resistance and pm2.5 filtration efficiency of masks. This instrument is a non-standard tester. Use air particles as the test medium to show the test results at a flow rate of 85 L/min. It is especially suitable for the horizontal contrast of different masks and do an advantage to the mask design, mask sales display, mask material selection and etc.
