HEPA & ULPA Filtration Validation for Cleanroom Environments
Automated HEPA and ULPA filter leak detection and efficiency testing systems compliant with EN 1822 and ISO 29463, designed for semiconductor, pharmaceutical, and clean manufacturing environments.
HEPA / ULPA Filtration Efficiency and Leak Integrity Testing
Cleanroom operators and filter manufacturers face dual challenges: verifying ISO Class 1–5 cleanliness performance and ensuring leak-free integrity for every filter unit. Achieving this requires rigorous scanning procedures in full compliance with EN 1822 and ISO 29463 standards.
SCPUR bridges the gap between laboratory standards and industrial production scale. We deliver comprehensive solutions, from high-speed automated scanning for standard panels to customized engineering solutions for complex filter geometries, ensuring operational stability and reliable GMP compliance.
Industry Challenges and SCPUR Solutions
Addressing manual inspection bottlenecks with automated filtration testing solutions.
Manual scanning is slow, labor-intensive, and prone to operator fatigue. It often struggles to keep pace with the high throughput of modern 24/7 production lines.
High-Speed Automated Filter Scanning:
Our robotic XYZ-axis scanning system operates at speeds up to 40 mm/s, enabling fully automated inspection and consistent quality verification for high-throughput production.
Standard probes struggle to maintain consistent sampling on non-standard geometries (e.g., V-Bank, cylindrical), resulting in detection blind spots and incomplete validation.
Flexible Engineering Adaptation: Customized fixtures and multi-axis path planning ensure full coverage for special shapes, eliminating dead zones in compliance with ISO 29463.
Traditional visual inspection relies on manual paper records, creating disconnected data silos that lack digital integration and fail to meet strict GMP traceability audits.
Digital Compliance & Visualization: Our software automatically generates 2D/3D leak distribution maps and traceable reports, fully compliant with GMP Annex 1 requirements.

From oil-thread inspection to automated scan testing
A manufacturer of H13/H14 HEPA filters supplying pharmaceutical and semiconductor cleanroom markets faced increasing quality control bottlenecks. By introducing automated scanning equipment, the inspection process moved from manual leak checking to standardized quantitative testing, improving consistency and production efficiency.
The Challenge
Limitations of Traditional Leak Testing
Traditional oil-thread or DOP leak tests are primarily designed to detect filter integrity defects.
However, these methods focus only on leak detection and do not provide broader performance evaluation such as filtration efficiency characterization or pressure drop monitoring.
As a result, manufacturers often require multiple separate test systems to fully verify filter performance.
Limited Diagnostic Information:
Traditional DOP inspection often focuses on pass/fail judgement and provides limited structured defect data, making systematic repair management and quality traceability difficult.
Our Solution
Automated Quantitative Scanning:Robotic XYZ-axis scanning performs consistent downstream particle sampling, enabling quantitative leak detection with high repeatability.
Defect Mapping and Repair Verification:Precise leak location mapping supports a structured Detect–Repair–Verify workflow, improving repair efficiency and quality consistency.
Integrated Performance Verification
Modern automated testing systems combine leak detection with airflow control, pressure drop monitoring, and particle counting, enabling a more complete and traceable evaluation of filter performance.
“Reliable quality control requires more than leak detection. Quantitative scanning enables defects to be located, repaired, and verified through a consistent and traceable testing process.”
