Mask melt blown cloth virus filtration efficiency tester

Mask melt blown cloth virus filtration efficiency tester

The main performance indicators of the mask virus filtration efficiency (VFE) detector comply with the Phi-x174 phage testing method for evaluating the virus filtration efficiency of medical protective mask materials in YY/T1497-2016. The dual gas path simultaneous comparison sampling method is adopted to improve the accuracy of sampling. It is suitable for performance testing of mask virus filtration efficiency by metrological inspection departments, research institutes, mask production enterprises, and other relevant departments. The VFE tester for mask virus filtration efficiency adopts technology and industrial computer control, with a user-friendly interface and operation mode designed to simplify user testing and facilitate direct display of test results, making it convenient and intuitive.
​​​​​​​

The mask virus filtration efficiency tester consists of a biological aerosol generation system, an aerosol chamber, an aerosol conveying device, a negative pressure cabinet, and a high-speed liquid impact sampler. The entire detector is uniformly controlled by a control system. The console adopts PLC+Labview 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.
