Mask Bacterial Filtration Efficiency (BFE) Detector Tester

Face Masks bacterial filtration efficiency BFE tester is to determine the bacterial filtration efficiency (BFE) of medical face mask materials by employing a ratio of the upstream bacterial challenge to downstream residual concentration of the tested medical face mask materials. The method of double air sampling is adopted to improve the accuracy of sampling, which is suitable for the performance test of bacterial filtration efficiency of surgical masks by metrological verification departments, scientific research institutes, medical mask manufacturers and other relevant. This Mask Bacterial Filtration Efficiency Tester is used to test the percentage of respirator material to remove bacteria-containing suspended particles at a specified flow rate. Features: Built - in peristaltic pump in the negative pressure cabinet, A, B, six Andersen; Built-in leakage protection switch to protect the safety of operators; Heat preservation and flame retardant between inner and outer layers; Negative pressure test system to ensure the safety of operators; The peristaltic pump flow can be set; Cabinet built-in high brightness lights; Front opening and closing glass door, convenient for experimenters to observe and operate; Detachable bracket with adjustable height; The flow rate of night spray of special microorganism aerosol generator can be set, and the atomization effect is good; Embedded high-speed industrial microcomputer control; 10.4 inch industrial high brightness color touch screen; USB interface, support U disk data storage; Supporting and moving dual-purpose casters.
