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.
