Nanofiber HEPA Filter Test in FFU Cleanroom System
To evaluate the real operating performance of nanofiber HEPA filters in cleanroom environments, NanoFiltech conducted an on-site FFU filtration test using H14 grade filters.
Test Overview
The test was carried out by replacing the original fiberglass HEPA filter with a NanoFiltech nanofiber filter in a Fan Filter Unit (FFU) system. Both filters had the same specification of 1170 × 1170 × 90 mm and were tested under identical operating conditions.
Key parameters recorded during the test included pressure drop, outlet air velocity, and energy consumption. Measurements were taken after 45 days of operation to ensure stable performance data.
Performance Comparison
The results showed that the nanofiber HEPA filter delivered clear advantages:
- l Lower pressure drop: 202 Pa vs 231 Pa for fiberglass filters
- Higher airflow performance: 0.55 m/s vs 0.43 m/s outlet velocity
- Lower energy consumption: 95 W at 800 rpm vs 297 W at 1100 rpm
Despite maintaining 100% initial filtration efficiency, the nanofiber filter significantly reduced system resistance and fan load.
Energy Saving Impact
Based on the average data collected during the 88-day test period, one NanoFiltech filter can achieve:
- 5.56 kWh energy saving per day
- Approximately 2,029 kWh energy saving per year (theoretical)
Pressure Drop Stability
Additional testing comparing NanoFiltechNAFILH14 filters with several fiberglass filter brands also showed consistently lower pressure drop across different airflow conditions, indicating improved lifecycle stability.
Conclusion
The FFU test demonstrates that nanofiber filtration technology not only maintains high-efficiency cleanroom filtration, but also reduces pressure drop and system energy consumption. For semiconductor, photovoltaic, and other high-cleanliness manufacturing environments, this translates into measurable long-term operational savings.
