Standards:

ISO 11155-1 (cabin air filters), ISO 5011 (engine pre-air filters), EN779/ASHRAE 52.2 (room air filters), EN 1822-3 (HEPA filters), CEN EN 143

Applications:

1. Testing of filter media and small mini-filters in product development and during production monitoring.
2. Testing option based on ISO 11155-1 (cabin air filters), ISO 5011 (engine pre-air filters), EN779/ASHRAE 52.2 (room air filters), EN 1822-3 (HEPA filters), CEN EN 143 and other standards in various versions.
 

Product Information:

filter test rig is a modular filter testing system for flat filter media and small mini-filters.
The G20 can be used to determine:
pressure loss curve on the medium without a dust coating,
fraction separation efficiency, or
burden and fraction separation efficiency during application of the burden
within shortest times – reliably and therefore cost-effectively.
The aerosol generators are easy to interchange and coordinated with the overall system. As a result, filter tests can be performed quickly and easily with the different test aerosols.
With the aid of the light scattering spectrometer Promo® 2000, clear and reliable determination of the aerosol concentration and the particle size and therefore an accurate determination of the fraction separation efficiency can be ensured.
The largely automated setup of the test sequence together with the clearly defined individual components and the individually adjustable sequence programs of the filter test software FTControl combine to deliver the high reliability of our measurement results.
Our quality in detail
 
Structure: 
1. Variable aerosol generation Thanks to the use of different dispersers for dusts, KCl/NaCl, DEHS etc.; shortened measurement times are possible e.g. through increased dust concentration
2. Corona discharge (optional): Adjustable ion stream for different mass flows. Mixed air, adjustable for inflow speeds from 0.05 to 1 m/s. Optional: Transient inflow.
3. Mobile pneumatic filter holder for fast removal and loading of the test rig.
4. Light scattering spectrometer Promo® system for clear particle measurements in high concentrations of up to 1000 mg/m3 (SAE Fine) with integrated Windows test rig software.
5. Easy to operate even for untrained personnel thanks to the automated sequence programs for performance of the filter testing. The test rig can be controlled fully automatically.
