ISO 29463-1 requires for all HEPA /ULPA filters with an efficiency of 99.95% or higher (ISO 35H/H13) the following test to ensure filter quality:
- local efficiency according to ISO 29463-4
- overall efficiency according to ISO 29463-5
The LFT 2000 combines the requirements of ISO 29463-4 Annex F for Class 35 H filters with a simple manual test procedure.
The system manually detects possible leakage points easily and quickly with the appropriate software.
The output of the test report is for local filter efficiency as well as for leak detection.
