Face Mask Particulate Filtration Efficiency Tester
Application
It is used to test the filtration efficiency of daily protective masks and medical masks on particulate matter, and to determine the obstructive performance of ordinary fabrics and medical protective masks against the constant flow of airflow.
Applicable to medical device inspection centers, safety protection inspection centers, labor protection inspection centers, drug inspection centers, disease prevention and control centers, textile inspection centers, hospitals, mask manufacturers, etc.
Applicable (1) Glass fiber filter material (2) PP filter material (3) Covered film
Principle
It is designed and manufactured in accordance with the standards of YY0469-2011 <Technical Requirements for Medical Surgical Masks> and GB2626-2006 <Respiratory Protective Equipment Self-priming Filtered Particle Respirators>. At the same time, it also refers to the advanced design concept of similar international equipment (such as the United States TSI company), based on the principle of <European Standard EN1822-3:1998 Single Filter Material Test>, but it is suitable for the current testing status of domestic related industries.
