Introduction
· The filter material comprehensive performance test bench is designed and manufacturing from experience the process of exploration and experiment, and with reference to YY0469-2004 "Technical requirements for surgical mask" and GB2626-2006 "Respiratory protective equipment - Non-powered air-purifying particle respirator" standard. At the same time, it also refer to advanced design concepts of the international similar equipment, (such as the United States TSI company), which based on the "European standard EN1822-3: 1998 Testing flat sheet filter media" principle, but suitable for domestic related industry test status.
· It can be used with DEHS aerosol generator or NaCl aerosol generator or the atmosphere of a variety of filter, medical masks and a variety of protective equipment resistance, flow, efficiency and other performance determination. User-friendly design, with a simple operation, easy to use, for a wide range of features. It can instantly to provide complete data parameters to the sample.
