I. Particulate matter filtration efficiency test Meltblown cloth PFE filtration efficiency tester Meltblown cloth detector Introduction

The BM-1000 filter material comprehensive performance tester is designed and manufactured according to the standards of YY0469-2004 "Technical Requirements for Medical Surgical Masks" and GB2626-2006 "Respiratory Protection Products Self-Suction Filtering Anti-Particle Respirator" through the exploration and experiment of the process flow . At the same time, it also refers to the advanced design concepts of similar international equipment (such as American TSI), based on the principle of "European standard EN1822-3: 1998 single-sheet filter material test", but it is also suitable for the test status of related domestic industries.

The performance of ventilation resistance, airflow resistance, particulate filter efficiency (PFE) and other performance measurements of various filter materials, melt-blown cloths, medical masks and various labor protection products can be performed with DEHS aerosol generator or NaCl aerosol generator or atmosphere, respectively . It has a humanized design, has the characteristics of simple operation, convenient use and wide application range. It can provide complete data parameters for sample sealing immediately.
