To reliably determine the quality and efficiency of filter elements, it is crucial to test energy consumption (pressure drop), loading, particle separation efficiency, and total penetration.
Accurate measurement requires adaptation of the test channel with regard to flow guidance and aerosol distribution to the size of the filter elements.
Palas has over 40 years of experience in filter testing and continuously develops test rigs of the highest quality to meet various requirements.
The FET 300 enables defined testing of filter elements up to 305 • 305 mm, such as ventilation filters, HEPA/ULPA filters, vacuum cleaner filters, and car cabin filters.
Designed for optimum flow guidance, the channel can also use adapters for smaller filter elements.
Coarse filters up to ULPA filters are tested for separation via particle size and differential pressure. The FET 300 measures better than the standards require:
- ISO 29463-5 HEPA/ULPA filter elements
- ISO 16890 room air filters
- ISO 11155-1/3 Automotive cabin air filters
- DIN 71460 Automotive cabin air filters
Thanks to individual adapters and customer-specific adaptations in the air duct, the FET system can be used for a wide variety of filter elements.
