Robot HEPA/ULPA Filter Scanning System

The Robot HEPA/ULPA Filter Scanning System is an automated test system designed to measure both integral and local particle filtration efficiency, as well as leak detection, of 2-dimensional and 3-dimensional HEPA and ULPA filter elements. The modular design allows the use of different test aerosols, including DEHS, paraffin oil, and PSL. Optical particle counters (OPC) are used by default, while SMPS measurements or DMA-classified aerosol tests combined with condensation particle counters (CPC) are also supported. The system is suitable for panel filters and cartridges at moderate flow rates and can be scaled for higher flows upon request.
