The Masks Bacterial Filtration Efficiency (BFE) Tester is mainly suitable for testing the bacterial filtration efficiency of masks in measurement and certification departments, research institutes, medical mask production units and related testing departments. It consists of an aerosol generation system, an aerosol chamber and aerosol transfer device, a negative pressure cabinet, a 28.3L/min sampler, etc. The whole tester is controlled by a console. The console uses a microcomputer control system to coordinate the work of the aerosol generation system, transmission system, negative pressure cabinet and sampling system, and to display the working status in real time, the whole measurement work is completed automatically.
