Instruction
Filter material test bench is designed by the process of exploration and experiment, and it’s in line with YY0469-2004 and GB2626-2006. At the same time also refer to the advanced design concepts of international similar equipment, (such as the United States TSI company), and it is based on the "European standard EN1822-3: 1998, but appropriate for domestic related industry test status.
Use DEHS aerosol generator or NaCl aerosol generator or the atmosphere to determine the resistance, flow, efficiency and other performances for a variety of filters, medical masks and anti-labor supplies. It’s the user-friendly design with a simple operation and a wide range of features. It samples the sample instantly to provide complete data parameters.
