Test Principle

Sample Installation: The filter is mounted in the filter holder, ensuring a secure fit.

Aerosol Generation & Flow: Aerosol (DEHS or PSL) is introduced at a controlled volume through the filter.

Leakage and Efficiency Measurement: Downstream particle concentration is measured via particle counters to calculate overall filtration efficiency and identify potential leaks.

Automated Data Collection: PC-controlled software records upstream and downstream particle counts and calculates efficiency and leakage locations.

Operation Instructions

System Startup:

- Configure and start all devices, including aerosol generator, particle counters, and airflow system.

- Install filter adapter according to sample dimensions.

Testing Process:

- Launch test; the system scans the filter using multiple probes, measuring leakage and overall efficiency automatically.

Data Recording & Reporting:

- Software generates a standard-compliant report, including efficiency and leak position.

Experimental Procedure

Preparation Stage:

- Verify all devices are operational.

- Install filter in the appropriate adapter.

Testing Stage:

- System conducts automated scanning and efficiency/leakage measurement.

Result Analysis & Report Generation:

- Test results are automatically compiled and saved in the software, including filter efficiency, potential leaks, and compliance with standards.
