Filter Tester HFP 2000
The Filter Media Test System is designed to evaluate the filtration performance of flat filter media and small filter elements. It measures particle separation efficiency, pressure drop, and filter performance during aerosol loading. The system uses aerosol generation, controlled airflow, differential pressure measurement, and aerosol concentration analysis to assess filtration performance under defined test conditions.
Automated test sequencing and programmable control help improve measurement repeatability and reduce testing time. The system supports analysis of initial filter performance, pressure loss curves, and changes in fractional separation efficiency during loading, making it suitable for filter media development, product evaluation, and quality control.
