2015 -- This new air filter test system is designed to meet requirements of EN1822-4 Appendix E “efficiency leakage test for particle sizes from 0.3 µm to 0.5 µm”. This part of the standard is related to filter elements which cannot be scanned due to its geometrical design. In this case determination of integral filtration efficiency is sufficient for quality control.
- Efficiency testing of small HEPA filter elements
- Confirmation of nominal HEPA filter class
- Suitable for integrated filter production control
- Very fast detection of defective filter elements
