Test system for large filter elements
Category：Filter Cartridge Filtration Tester
Introduction
Applications
The Test System for Large Filter Elements is designed for performance evaluation of high-capacity filters. Ideal applications include:
Development and R&D – Optimize filter designs and verify separation efficiency
Quality Control – Monitor production consistency for cabin, engine, and clean room filters
Filter Performance Testing – Evaluate HEPA/ULPA filters, cabin air filters, engine air filters, and compressor supply air filters
Specialized Measurements – Determine MPPS (Most Penetrating Particle Size) and fractional separation efficiency
Standards Compliance
The system supports internationally recognized standards to ensure accurate and comparable results:
ISO 29463-5 – High-efficiency filter testing (HEPA/ULPA)
ISO 16890 – Fractional separation efficiency for air filters (ISO ePM1, ISO ePM2.5)
