BFE detector intelligent mask detector

Description :

　　The main configuration of the bacterial filtration efficiency detector is:

　　1. One negative pressure test chamber;

　　2. One set of test stand;

　　3. A set of peristaltic pumps;

　　4. Two sets of flow sensors;

　　5. One set of vortex mixer;

　　6. One set of aerosol generator;

　　7. Two sets of gas collection sensors;

　　8. A set of measurement and control computers;

　　9. One set of experimental software;

　　10. A set of HP color inkjet printers.

　　Several technical features of the mask bacterial filtration efficiency detector:

　　1. Key counting module control: digital display counter, can preset 1-99999s time for testing, automatically stops after testing is completed;

　　2. Anti genuine head mold: The mask fixture is a metal human head mold that can fully simulate the actual usage state of the mask;

　　3. High degree of equipment automation: The instrument automatically records the combustion time and flame retardant time, with digital display, equipped with flame temperature measurement probes and flame temperature displays, automatic ignition, and adjustable flame height;

　　4. Negative pressure experimental system to ensure the safety of operators;

　　5. The negative pressure cabinet is equipped with a peristaltic pump, A and B channels of six stages Anderson;

　　6. The flow rate of the peristaltic pump can be set;

　　7. The flow rate of bacteria spray at night of microbial aerosol generator can be set,

　　8. Good atomization effect;

　　9. Embedded high-speed industrial microcomputer control;

　　10. 10.4-inch industrial grade high brightness color touch display screen;

　　11. USB interface, supporting USB data transfer and storage;

　　12. The cabinet is equipped with high brightness lighting fixtures;

　　13. Built in leakage protection switch to protect the safety of operators;

　　14. The inner layer of the cabinet is made of stainless steel and processed as a whole, while the outer layer is made of spray coated cold-rolled plate,

　　15. Insulation and flame retardancy between the inner and outer layers;

　　16. Front switch glass door, convenient for experimental personnel to observe and operate;

　　17. Detachable bracket with adjustable height;

　　18. Dual purpose casters for support and mobility.

　　The testing principle of the bacterial filtration efficiency tester is to simulate the actual use state of the mask sample and install it on the head mold rack. The mask passes over the igniter with a constant flame height at a certain linear velocity along with the head mold, observes the combustion of the mask, records the duration of continuous combustion and smoldering, and evaluates whether the mask is qualified.

　　Instructions for Bacterial Filtration Efficiency Tester: The main performance indicators not only comply with the requirements of Appendix B Bacterial Filtration Efficiency (BFE) Test Method B.1.1.1 of the "Technical Requirements for Medical Surgical Meltblown Filter Media" YY0469-2011, but also meet the requirements of the American Society for Testing and Materials ASTMF2100, ASTMF201, and European EN14683 standards. Based on this, innovative improvements have been made, using a dual gas path simultaneous comparative sampling method to improve the accuracy of sampling. It is suitable for performance testing of bacterial filtration efficiency of meltblown filter media by metrological inspection departments, research institutes, meltblown filter media production enterprises, and other relevant departments.
