Introduction
Filter material test bench is designed and manufactured based on the exploration and experiments on the technological process with reference of YY0469-2004 and GB2626-2006. At the same time it takes the reference of advanced designing 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 the test status in domestic related industry.
DEHS aerosol generator or NaCl aerosol generator or the atmospheric air to determine the resistance, flow, efficiency and other performances for a variety of filters, medical masks and labor protection products. The user-friendly design features simple operation and a wide range of application. It provides a complete data parameter to the sample instantly.
