【Scope of application】
The instrument uses multi-dispersion experimental aerosols (DEHS or NaCl) for quantitative dust generation, and under the action of clean airflow (negative pressure type), conventional performance tests are carried out through aerosol particle sampling and differential pressure measurement points in the upstream and downstream of the filter media under the action of clean airflow (negative pressure type).
