Robot HEPA/ULPA Filter Scanning System，robotic filter leak and efficiency test system
The Robot HEPA/ULPA Filter Scanning Detection System is designed to evaluate both overall and local particle filtration efficiency of 2D and 3D filter elements, including leakage detection. You can perform efficiency testing using multiple aerosol types, including DEHS, paraffin oil, and PSL. The system integrates optical particle counters (OPC) by default and can optionally use condensation particle counters (CPC) or scanning mobility particle sizers (SMPS) for size-classified aerosol measurements. Initially designed for moderate-flow panel filters and cartridges, the system can be expanded for higher-flow applications.
Application
You can apply this system for:
Product Development & Quality Control: Evaluate and ensure HEPA/ULPA filters meet high-efficiency particle removal requirements.
Filter Scanning: Scan both panel filters and cartridges for comprehensive inspection.
3D Scanning: Support V-shaped or other 3D filters for detailed local efficiency mapping.
High-Flow Filter Testing: Expand the system to test higher-flow filters as needed.
Innovative Testing: Automated 3D scanning increases flexibility and precision compared to conventional methods.
Standards
The system is compliant with, but not limited to:
(1) GB 4706.1 – Safety of household and similar electrical appliances, Part 1: General requirements.
(2) EN 1822 – High-efficiency air filters (HEPA and ULPA) – Design and test methods.
(3) JIS B 9900 – Japanese industrial standard for air filtration devices.
(4) IEST-RP-CC001 – Performance and testing of cleanroom air filters for HEPA/ULPA.
(5) ASTM F1471 – Standard test for particle contamination in air and HEPA filter evaluation.
(6) ISO 29463-5 – HEPA/ULPA filter performance evaluation, Part 5: Filter efficiency and leakage detection.
(7) ISO 29463-4 – HEPA/ULPA filter performance evaluation, Part 4: Aerosol testing requirements.

Test Procedures
Preparation:
Select the filter type and ensure it fits within the system’s sample range.
Set up the aerosol generator, select the appropriate aerosol type, and preheat the system.
Testing:
Install the filter securely on the robot work platform.
Start the scanning system; the robot will automatically perform the scanning operation according to set parameters.
Data Analysis:
Collect efficiency and leakage data via OPC, CPC, or SMPS.
Generate detailed filter performance reports, including overall efficiency, local leakage points, and MPPS curves.
Maintenance Information
Wear appropriate PPE, including gloves and protective eyewear.
Ensure proper ventilation when handling aerosols.
Regularly inspect aerosol generators, particle counters, and robot components.
Keep the system clean and calibrated to maintain accurate performance.
