Nanofiber V-BankHEPA Filter Test in MAU + FFU System
Energy Saving Case Study – Top 3 Photovoltaic Manufacturer
To further evaluate nanofiber filtration performance in high-cleanliness production environments, NanoFiltech conducted an 88-day on-site test at a Top 3 photovoltaic manufacturer in China.
Test Overview
Ø Application: MAU + FFU cleanroom system
Ø Air volume: 80,000 m³/h
Air change rate: 15 times/hour
Filter type: V-bank air filter
Installation quantity: 24 units
Measuring instruments: Anemometer, energy meter, efficiency tester
Both nanofiber and traditional fiberglass V-bank filters (592×592×292, 4V) were tested under identical operating conditions.
Key Performance Comparison
MAU Brand X
Parameter | Nanofiber | Fiberglass |
Initial efficiency | 99.90% | 93.80% |
Pressure drop | 120 Pa | 200 Pa |
Energy consumption | 30 kWh @ 30Hz | 32.96 kWh @ 30Hz |
MAU Brand Y
Parameter | Nanofiber | Fiberglass |
Initial efficiency | 99% | 95% |
Pressure drop | 100 Pa | 160 Pa |
Energy consumption | 27 kWh @ 30Hz | 27.84 kWh @ 31Hz |
Energy Saving Result
Based on 88 days of operational data:
- 4.18 kWh saved per hour
- 3,661 kWh saved per year (per 80,000 m³/h MAU unit, theoretical)
Technical Insight
The test demonstrates that nanofiber surface filtration provides:
- Higher initial efficiency
- Significantly lower pressure drop
- Reduced fan frequency requirements
- Lower long-term system energy consumption
In photovoltaic cleanroom environments where MAU + FFU systems operate continuously, even small reductions in pressure drop translate into measurable lifecycle cost savings.
NanoFiltechfocuses not only on filtration efficiency, but on system-level energy optimization and lifecycle stability.
