Test Principle
Overall Efficiency Testing:
DEHS aerosol is generated upstream; particle concentrations are measured upstream and downstream.
Upstream concentration is measured with an optical particle counter and adjusted via the dilution system.
Downstream concentration is measured similarly; overall efficiency is calculated and compared to nominal target.
Efficiency Comparison:
Overall measured efficiency is compared with target efficiency to quickly classify “pass” or “fail.”
Differential Pressure Measurement:
Measures pressure drop across the filter element, generating pressure curves and dust loading capacity data to ensure stable performance at different flow rates.
