Mask bacterial filtration efficiency (BFE) detector

Mask bacterial filtration efficiency (BFE) detector

The mask bacterial filtration efficiency (BFE) tester is mainly suitable for testing the performance of mask bacterial filtration efficiency in metrological verification departments, research institutes, medical mask production units, and related testing departments. Mainly in accordance with Appendix B of YY0469-2011 Technical Requirements for Medical Surgical Masks - Test Method for Bacterial Filtration Efficiency (BFE) - Test Instrument Requirements B.1.1.1. It also meets the requirements of ASTM F2100, ASTM F2101, and EN 14683 standards.

Product Introduction:

The mask bacterial filtration efficiency (BFE) detector adopts a dual gas path simultaneous comparison sampling method, which improves the accuracy of sampling. It is suitable for performance testing of mask bacterial filtration efficiency by metrological verification departments, research institutes, mask production enterprises, and other relevant departments.

Compliant with standards:

Appendix B of YY0469-2011 Technical Requirements for Medical Surgical Masks - Bacterial Filtration Efficiency (BFE) Test Method Section B.1.1.1

Q/0212ZRB003-2011 Medical Surgical Mask Bacterial Filtration Efficiency (BFE) Tester

ASTMF2100, ASTMF2101, European EN14683

Product principle:

Consisting of an aerosol generation system, an aerosol chamber and aerosol transport device, a negative pressure cabinet, a 28.3L/min sampler, etc., the entire detector is uniformly controlled by a control console. The control console adopts 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.

Technical features:

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

2. The negative pressure cabinet is equipped with a peristaltic pump, with six stage Andersen for both A and B circuits;

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

4. The flow rate of the special microbial aerosol generator at night can be set, and the atomization effect is good;

5. Embedded high-speed industrial microcomputer control;

6.10.4 inch industrial grade high brightness color touch screen;

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

8. The cabinet is equipped with high brightness lighting;

9. The inner layer of the cabinet is made of stainless steel and processed as a whole. The outer layer is sprayed with cold rolled sheet, and the insulation and flame retardant properties between the inner and outer layers are maintained;

10. Detachable bracket, adjustable in height, supports and moves dual-purpose casters.
