The test bench uses polydisperse experimental aerosols (DEHSorNaCl2) Quantitative dust generation, and under the action of clean air flow (negative pressure type), the regular performance test shall be carried out through aerosol particle sampling and pressure difference measuring points upstream and downstream of the tested filter material.The test bench refers to the advanced design concept of similar international equipment (such as the United States.TSI company 8130 models), but also suitable for the domestic related industry testing status quo. Independent research and development of the program software is stable and reliable, easy to operate. Simple running interface, running parameters at a glance. Different dust sources (DEHSandNaCl）Switch freely, suitable for a variety of air filter materials (melt blown, glass fiber,PP, film and other filter materials), medical masks and some labor supplies testing.
