Mask EN149:2019 N95 Respirator And Filter Clogging Testing Machine
Scope of application:
The filter and mask obstruction tester is used to test the amount of dust collected on the filter when the airflow passes through the filter under a certain dust environment and the airflow passes through the filter to reach a certain breathing resistance. Breathing resistance and filter penetration.
