The Filter Media Test Rig is designed for characterization of filter media and small-scale filter elements according to various standards. It measures key parameters such as differential pressure, gravimetric separation efficiency, fractional efficiency, and dust loading capacity. Reliable and repeatable testing is critical for development, optimization, and quality assurance of filter media.
The system is applicable for:
(1) Cleanable Filter Media: Testing in accordance with VDI 3926-2.
(2) Air Filter Testing:
- General air filters (ISO 16890, EN 779, ASHRAE 52.2)
- High-efficiency filters (EPA, HEPA, ULPA, ISO 29463)
- Cabin air filters (DIN 71460-1 / ISO/TS 11155-1)
- Engine intake filters (ISO 5011)
(3) Filter Media Development and Optimization: Laboratory and R&D testing.
(4) Quality Assurance: In-line production monitoring and final inspection.
(5) Flat Media Quality Control: Pre-processing or post-production inspection of planar media.
The system can execute and complies with:
(1) ISO 16890 – Air filter classification standard.
(2) ISO 29463 – High-efficiency filter performance standard (EPA/HEPA/ULPA).
(3) ISO 5011 – Engine and industrial machinery air filter testing.
(4) ISO/TS 11155-1 – Automotive air filter performance testing.
(5) ISO 11057 – Clean air filter media performance testing.
(6) VDI 3926-2 – Characterization of cleanable filter media.
(7) EN 779 – High-efficiency air filter testing.
(8) ASHRAE 52.2 – Air filter performance standard.
(9) DIN 71460-1 – Automotive intake filter performance testing.

Differential Pressure Testing: Filter media is securely mounted in a test fixture. Differential pressure across the filter is measured to determine filtration efficiency and dust loading.
Fractional Efficiency Measurement: Optical particle counters measure filtration efficiency from 0.2 to 10 µm. Sample switching units ensure single-device measurement.
Dust Loading & Capacity: Measures pressure increase under varying dust loads; filter weight is recorded electronically to ensure accuracy.
System Startup:
- Verify all connections (air, power, aerosol generator) and calibrate equipment.
- Configure test parameters (aerosol type, flow range) and start the system.
Safety:
- Avoid direct contact with aerosols; wear gloves and safety glasses.
- Monitor differential pressure, flow rate, and system status.
Filter Replacement:
- Use the fixture to remove or replace filter media safely and efficiently.
Experimental Procedure
Preparation:
- Set test conditions according to selected standards (ISO 16890, EN 779, etc.).
- Install and secure filter media in the test fixture.
Testing:
- Start the system; automated measurement of differential pressure, fractional efficiency, and dust loading.
- System adjusts flow and aerosol concentration as needed.
Data Recording & Reporting:
- After completion, generate test reports including differential pressure curves, fractional efficiency, and dust loading.
- Export data for analysis and documentation.
Regularly clean and calibrate aerosol generators and particle counters.
Check airflow and differential pressure sensors periodically.
Keep system components free of dust and contamination.
